Abstract: PROBLEM TO BE SOLVED: To provide the electronic mail system used efficiently for a recipient relieved from a load of an access operation by receiving and storing automatically electronic mail information. SOLUTION: Computer terminals 2A-2C are respectively provided with reception boxes 5a-5c that receive and store electronic mail information automatically, allow personal computers 2a-2c to operate to confirm reception of an electronic mail by the connection to a provider 3. It is not required to receive electronic mail information by the access processing. The reception of the electronic mail and whether or not it is from a designated sender are discriminated based on a time zone of lighting of incoming call display lamps of the reception boxes 5a-5c, number of items of electronic mail information not read yet is detected by display of an item number display device, and the electronic mail information is read corresponding to the frequency of use of the user efficiently without a load of operation. The electronic mail information is read in a confidential state at all times by the password operation of the recipient of the destination name.

Abstract: PURPOSE:To measure the dispersibility of toner mixed into an ink electrically with high accuracy. CONSTITUTION:The dispersibility measuring apparatus comprises a LED 1 disposed in an ink mixed with toner, a photosensor 2 disposed in the ink and receiving the light L emitted from the LED 1, a stirring means for fluidizing the ink, a detection circuit 12 for taking out an optical detection signal (s) from the photosensor 2, and a control circuit 13 for feedback controlling the optical output from the LED 1 based on an amplified signal S of an optical detection signal (s) from the photosensor 2. The detection circuit 12 comprises an RMS converter delivering the effective value of the optical detection signal (s) from the photosensor 2. The control circuit 13 comprises a low-pass filter 14 for the amplified signal S, and an operational amplifier 15 for taking out the difference between the level of an output signal SL and a reference level Sb.

Abstract: PURPOSE:To prevent an abnormal operation of a circuit and to reduce noise. CONSTITUTION:This device is provided with an airtight case 1 which houses a printed circuit board 5 in it and a cooling fan 8 which blows the outside air against the airtight case 1. The fan 8 is located outside the airtight case 1, therefore the outside air and dust are prevented from entering the airtight case 1 and no dust is collected on the printed circuit board 5 in the airtight case 1. Dust cannot enter the airtight case 1, and also the resonance of the case due to the sound of wind is prevented.

Abstract: PURPOSE:To improve freedom of wiring pattern design by forming a cutout in a mounting side end edge of a contact maker. CONSTITUTION:A wiring pattern constituting a printed circuit is formed on both sides of a board 11. A plurality of through-holes 12, 13 for connecting a wiring pattern, and a land extending to an opening periphery of the through- holes 12, 13 are provided to the board 11. A terminal 14 for probe connection is mounted on a terminal mounting surface 11a of the board 11. The terminal 14 is formed of a contact maker which consists of an approximately reverse T-shaped terminal main body 15 having a stopping hole 15a opened in both edge faces, and connectors 16, 17 which are projectingly provided to a terminal mounting side end edge of the terminal main body 15 and can be inserted to the through-holes 12, 13. A cutout 18 opened downward is formed in a mounting side end edge of the terminal main body 15, and two contact parts 20, 21 are provided which are connected to the land by the cutout 18 and cross a pattern wiring 19 on the terminal mounting surface 11a. Thereby, freedom of wiring pattern design can be improved.

Abstract: PURPOSE:To achieve the miniaturization of a device and the reduction in maintenance costs, to shorten the time required for printing in the case of a consecutive printing, and to increase the latitude of design. CONSTITUTION:A mobile body 21 applied with photosensitive body is electrified and irradiated with light, an electrostatic latent image is formed on the mobile body 21 by means of electric discharge to be developed and then transfers the image to printing paper 39 by means of heat and pressure. The mobile body 21 of the printer is set in the form of a sheet. Thus, since the external size of the mobile body 21 can be miniaturized, it can be operated so as to move independently of each processing device.

Abstract: PURPOSE:To satisfactorily detect liquid concentration with a simple structure by intermittently disposing light transmission members between light emitting means and photoreceiving means disposed in liquid. CONSTITUTION:One loop is formed of a photodiode 4 (photoreceiving means), an amplifier 5, a low-pass filter 6, an operational amplifier 8, a pulse width modulator 1 and an LED 2 (light emitting means). When a transparent rotary plate 3 (light transmission member) is rotated, a width of liquid to be measured is increased or decreased to vary a transmission amount of an optical path, and hence an output of the amplifier 5 is varied. This output is compared with a reference level by the amplifier 8, pulse width modulation-controlled by its difference to drive the LED 2, and hence so fed back that an input of the diode 4 becomes constant. That is, a low level sampled by a MIN value sample and hold circuit 11 is fed back to the modulator 1 to make the low level constant. Thus, a high level output sampled by a MAX value sample and hold circuit 9 becomes a stable concentration output.
