PURPOSE:To improve the verticality, wear resistance, rigidity, and thermal conductivity of a tape guide part and to obtain a magnetic tape cassette of superior sound quality by forming the tape guide block of the composite material of a ceramic material and synthetic resin. CONSTITUTION:The tape guide block of the magnetic tape cassette is molded by injecting the composite material of powder or fiber of fine ceramics (SiC, Si3N4, etc.) and polyamide, polybutylene terephthalate, or other resin. Consequently, the wear resistance, thermal conductivity, and rigidity of the tape guide block 24 are superior to those of a plastic block and the magnetic tape cassette of superior sound quality is obtained.

Abstract:
PURPOSE:To continuously give suitable moisture and to obtain stable wipe effect and further, to prevent static electricity, by providing a transparent tank storing the cleaning liquid in the cleaner main body and making wet through the supply of this liquid to the main body from the tank. CONSTITUTION:The holder 2 is made of wooden material of rectangular parallelopiped, the side surfaces 2a and 2b are mutually formed parallel and flat, the concave 6 of approximately rectangular parallelopiped is formed on the upper part of the holder, and the cylindrical projection 7 is formed at the left side wall. The open end of the transparent cylindrical glass tank 3 is inserted to the projection 7 and it is mounted in the concave 6 with the condition that it is held horizontally with the support stand 11. Cleaning liquid is stored in the tank 3, the cleaning liquid path 8 is provided in the left side of the holder 2, the thread 9 is inserted in the path, and one end is immersed to the liquid and another end is in contact with the moisture absorption material 5. Thus, wiping and destaticized effect can stably be obtained.

PURPOSE:To provide a construction of turntable sheet, in which hard base plate is interposed and bonded between one resilient sheet having viscous material enclosed therein and another resilient sheet incorporating no viscous material, whereby troubles due to deflection of record plate or vibration of turntable can be prevented.
Abstract:
PROBLEM TO BE SOLVED: To provide a network system that can sufficiently effectively utilize frequency bands and to provide a communication method, an optical communication apparatus and method. SOLUTION: In the network system and the communication method of this invention, a control and management means for controlling and managing each information device connected by a communication channel transmits a prescribed control signal to a corresponding information device or all information devices on request of transmission of a data signal from the information devices, and the corresponding information device or all the information devices filter the data signal as required so as to route only required paths among communication channels on the basis of the control signal received from the control management means. Further, in the optical communication apparatus and method, a corresponding light emission means among a plurality of the light emission means is subjected to blink drive according to a type of supplied information, lights emitted from the light emission means are multiplexed, and the multiplexed light is outputted to a prescribed connected optical communication line.

Abstract:
PROBLEM TO BE SOLVED: To select and display a Web page at the destination of transition based on each operation of plural cursors by plural users. SOLUTION: Plural cursors Cur1, Cur2,..., CurN operated by plural remote controllers (remote commanders) are respectively stored in position expression layers Pos1, Pos2,..., PosN (a figure 7 (A)), and the cursor Curn stored in each position expression layer Posn is projected to an all position expression layer all (figure 7 (B)). Moreover, the cursors Cur1, Cur2,..., CurN stored in the all position expression layer all are displayed so as to be overlapped in a Web page (figure 7 (C)). Then, any of the other Web pages to which the Web page is linked is selected based on the position indicated by each cursor Cur1, Cur2,..., CunN, and the selected Web page is displayed.
Abstract:
PROBLEM TO BE SOLVED: To identify whether a signal recorded in a signal recording medium is an original signal or a copied one, by recording in a medium a video signal and/or an acoustic signal into which an identification signal is inserted. SOLUTION: A video signal inputted to a terminal 1 is inputted to an addition circuit 3 via an A/D converter 2, and an identification signal is added to the least significant bit of the luminance signal of the digital video signal inputted from the terminal 28. The signal is provided with compression encoding in a compression encoding circuit 4 according to MPEG 2 Standard and is sectored in a sector circuit 5, which adds an error detection sign to the signal. After a header is added to the signal in an addition circuit 6, a parity bit is added to the signal in a encoding circuit 7, and the signal is then converted into modulated data of 16-channel bit in a modulation circuit 8, and a synchronizing signal of an out-of-rule pattern is added in an addition circuit 9 and the signal is recorded in an optical disk 12 with a recording/reproducing head 14.
