Title: Tape recorder
Inventor: UMEZAKI KIYOSHI
IPC: G11B15/675
Filed: 1988-02-29
Abstract: PURPOSE:To reduce the pushing amt. and load of an ejecting button by moving a head board and ejecting arm by the elasticity of a spring and providing the ejecting control member releasing the holding of the ejecting arm by the force that the head board returns to its storage position. CONSTITUTION:A head board 33 is moved by the spring energizing force in the opposite direction to an arrow mark D due to an ejecting operation being detected with an ejecting switch 60 being changed from a close to an open when an ejecting rod 57 is pushed in the arrow mark M direction. When an ejecting control lever 58 is turned in a clockwise direction centering around 57a by the spring force of the head board 33, an ejecting locking plate 9 is turned in a counterclockwise direction by the engagement of an inclined part. The holding of an ejecting arm 1 is released by the turning of the ejecting locking plate 9 and it is turned in a clockwise direction by an ejecting spring 8 to perform the ejecting operation of a tape cassette. When the ejecting opera tion is executed by this method, the operation force can drastically be reduced compared to the method of ejecting by pushing the tape directly due to the load of only the load of the ejecting rod spring 61 which becomes the returning power of the ejecting rod 57.

Abstract: PURPOSE:To inform a fault to a sender without useless data retransmission by allowing a data transmitter to detect and store the signal interruption from a data processing unit and to respond to a fault informing frame when a station receives the data. CONSTITUTION:Data processing units 31-34 are connected to a common transmission line 10 via data transmitters 21-24 respectively.

The circuit 107 generates a control signal (b) and stores the reception frame to a buffer 105. When a signal interruption detecting circuit 109 detects the interruption of a packet data from the unit 33, an FF 101 is set. When the circuit 107 receives a storage end signal C of the buffer 105, the FF110 is checked, and when the FF 110 is set, a fault informing frame is generated in a transmission register 108 and it is transmitted to the sender via a transmission circuit 102.

Abstract: PURPOSE:To prevent display characteristics from variation due to the change of a tilt angle by moving polarizing plates in accordance with the change of the tilt angle of ferroelectric liquid crystal which is generated due to temperature change and keeping the positional relation between the tilt angle and a polarizing axis at a fixed value. CONSTITUTION:The titled device is provided with a liquid crystal element 1 obtained by sealing ferroelectric liquid crystal 5 between a pair of bases, the polarizing plates 8, 10 arranged on the outsides of the bases of the element 1 and a polarizing plate control means for displacing the polarizing plates 9, 10 so that the angles of the polarizing axes of the polarizing plates 9, 10 from the liquid crystal element 1 are changed. The polarizing plates 9, 10 are rotationally displaced so that their polarizing axes A, B are set up on the positions corresponding to the tilt angle theta of the ferroelectric liquid crystal 5. Thus, the polarizing axes A, B of the polarizing plates 9, 10 can be always set up on the positions corresponding to the tilt angle theta of the liquid crystal 5 by displacing the polarizing plates 9, 10 in accordance with the change of the tilt angle theta due to the temperature change of the liquid crystal 5 in the element 1 and controlling the positions. Consequently, the contrast of 'bright' display and 'dark' display can be held at a constant value.

IPC: G06F15/16
Filed: 1989-03-01
Abstract: PURPOSE:To accurately read histories of program execution of plural processors dependent upon trace information at the time of debugging and to perform sure debugging by simultaneously storing a synchronizing signal mark in trace memories of respective processors as trace information. CONSTITUTION:At the time of storing the trace information, for example, a processor 1-0 outputs an interrupt signal to an interrupt signal line 3 and periodically sends it to the other processors 1-1 to 1-4. Consequently, the other processors 1-1 to 1-4 periodically and simultaneously this interrupt signal and simultaneously store the synchronizing signal mark in their own trace memories 2-1 to 2-4 as trace information. Then, synchronizing signal marks which are not deviated from one another with respect to time are stored and held in trace memories 2-0 to 2-4 of processors 1-0 to 1-4. Thus, the time lag among histories of the execution program of processors 1-0 to 1-4 is eliminated, and they are synchronized with one another to execute sure debugging.

Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To further improve the quality of the treated water discharged in a waterway by subjecting the residue to oxygen oxidation, oxygen-assisted anodization and then ozone oxidation. SOLUTION: In the aeration stations 5 and 6, a spent developer (residue A) and a residue B obtained by diluting a spent and desivered fixing bath, a bleaching and fixing bath and a bleaching bath with water are treated with oxygen in the air to oxidize a relatively oxidizable harmful matter, especially a sulfite.
