Title: Vertical magnetic recording/reproducing device
Inventor: NISHIDA YASUTAKA
IPC: G11B5/09
Filed: 1994-06-28
Abstract: PURPOSE:To prevent reduction of the outward magnetic flux leakage to be used for reproduction by inversing the recording current in a specified section of a recording pattern at a time interval shorten than a bit length and thereby forming reversed polarity magnetization. CONSTITUTION:The recording current control device 34 determines the recording current flowing from the recording pattern 1 to the recording head 38 and controls the recording amplifier 36 to make the recording current 21 flow to the recording head 38, which vertically magnetizes the mono-layer vertical magnetizing body 39 for recording the recording current 21. At the time of reproduction, the MR head 40 reproduces the recording pattern, which is amplified using the reproducing amplifier 41 to obtain a reproduced waveform 24. In the recording pattern 1, pulsive current inversion is applied in the region where no inversion of the recording pattern occurs over two-bit lengths. Hence, pulsive reversed polarity magnetization is formed by inversing the recording current of the region where the same recording current continues over two-bit lengths at a time interval shorter than one-bit length.

As a result, a wrapped button 1 with the light reflective surface 2a on top is formed. The button 1 so formed is then attached to each type of wear as a functional button or an accessory button. Thus, the button 1 can be concurrently used for the security of safety.

Title: On vehicle television device
Inventor: TOJO SEIICHI
IPC: H04N5/445
Filed: 1987-06-12
Abstract: PURPOSE:To give no uneasy sense to a crewman even if a TV image is turned off suddenly, by informing to the crewman the information by which a fact that its picture is not outputted due to running is known, at the time of turning off an image of a TV broadcast by following up the running of a vehicle. CONSTITUTION:In case a running detecting means 503 does not detect running of a vehicle but a running signal is not outputted, a switching means 504 sends a sound signal and an image signal which have been received and demodulated, to a TV receiver 501. Therefore, the TV receiver 501 functions normally. When the vehicle runs and the running signal is outputted from the running detecting means 503, the switching means 504 cuts off at least the demodulated image signal, and sends a voice or image information for showing a fact that the TV cannot be used in the course of running, from an output means 502 connected to a VTR, etc. As a result, for instance, a voice or an image of 'a television is not reflected in the course of running' is outputted from the TV receiver 501.

Title: Manufacture of mos transistor
Inventor: MIYAZAKI YOSHIHISA
IPC: H01L29/78
Filed: 1993-06-17
Abstract: PURPOSE:To reduce thermal stress occurring at high temperature thermal treatment and to suppress the occurrence of crystal defect by adjusting impurity concentration added to a silicate glass so that the difference in thermal expansion coefficients between the silicate glass and substrate is less than a specified value. CONSTITUTION:After a gate electrode is formed as before, a PSG film 8, containing P concentration 2weight%, is formed by thermal CVD for better coverage, and a side wall 9 is formed by anisotropic etching. Then, with the same processes as before, LDD structure will be formed. Although P is employed as impurity for a silicate glass used for the side wall, the impurity concentration to be added to must be adjusted so that the difference in thermal expansion coefficients between the silicate glass and substrate is 0.5X10<-6>/ deg.C or less. With this, since thermal stress occurring at high temperature thermal treatment is reduced and occurrence of crystal defect is suppressed, junction leak current is hard to occur, so that a MOS transistor of high reliability is formed.

Title: Encoding and decoding device for sequential reproduction of picture signal
Inventor: MURAKAMI ATSUMICHI
IPC: H04N7/26
Filed: 1987-06-12
Abstract: PURPOSE:To adaptively control the generation quantity of encoded information and the quality of reproduced picture in frame unit in a wide range by adaptively selecting and switching turning-on/off operations of plural encoder and decoders in accordance with the number of times of encoding of each frame. CONSTITUTION:In the first stage of encoding, an input signal vector 1 passes a subtractor 2 as it is and is outputted as a residual signal vector 3. A switch 4 turns on only an average value encoder and decoder 6 by a control signal 22 from an encoding control part 21. In the second stage of encoding, a decoded vector in the preceding stage is subtracted from the vector 1 to obtain the vector 3 by the subtractor 2, and the switch 4 turns on the encoder and decoder 6 and a normalized vector quantization encoder and decoder 7 by the signal 22. In the third stage of encoding, the vector 3 is obtained from the subtracter 2 similarly to the second stage, and the switch 4 turns on only a sample value encoder and decoder 5 by the signal 22. Even a rough picture is reproduced in the first stage, and a picture whose quality is higher than that of the preceding stage is reproduced in the second stage, and a picture whose quality is higher than that of the preceding stage is reproduced in the third stage.

Title: Monostable multivibrator
Inventor: HARASAWA AKIO
IPC: H03K3/02
Filed: 1989-06-09
Abstract: PURPOSE:To obtain a highly stable monostable multivibrator suitable for circuit integration by inverting an output bit sequentially with a clock signal to constitute the monostable multivibrator in a digital way. CONSTITUTION:With a trigger pulse TP supplied to a terminal 2, a front ridge detection circuit 3 detects its trailing edge and outputs a front ridge detection pulse FDP in a pulse width corresponding to one period of a clock signal CK. Since the pulse FDP resets a shift register 4, the level of all output terminals 5 of the register 4 descends to '0' level. Since a data 1 is inputted to the register 4 according to a signal CLK, each output bit of the register 4 inverts the output to a level 1 sequentially from the 1st stage to the final stage. Thus, a monostable multivibrator output having an optional quasi-stable period is obtained depending on what stage of output bit of the terminals 5 is to be used.

Title: Floppy disc driving device
Inventor: SAITO SHUNJI

Abstract: PURPOSE:To set the time keeping the drive of a motor sufficiently longer even when the input of a motor-on signal is stopped by providing a detector detecting the index hole of a floppy disc and a counter which is reset by the motor-on signal and outputs a motor drive signal. CONSTITUTION:At every time a detector 16 detects the index hole 15 of a floppy disc 13, the flip-flops 12... of a counter 11 are set sequentially. That is, since an index pulse INX is counted by the counter 11 to form a drive keeping time of a motor 14 after the stop of the motor-on signal MON, in case, for example, the floppy disc 13 is driven at 360 RPM, the index pulse INX is generated in a rate of once per 200ms and the 10 sets of the flip-flops 12 are used, the time becomes 2sec and when 100 sets of the flip-flops 12 are as long as 20sec. Since flip-flops and a conventional index hole detector 16 as well may be used, the constitution is simple.
