Title: Data separator for floppy disk
Inventor: KAWASAKI TAKESHI
IPC: G11B20/10
Filed: 1983-07-12
Abstract: PURPOSE:To lock precisely in phase and to increase the peak shift margin by switching filters after detecting that the phase shift amount is reduced less than a certain set level in a phase synchronizing process. CONSTITUTION:A CLP is equal to a signal corresponding to a clock pulse of an input data pulse with its width equal to the difference of phase between the input data pulse and a window pulse and can be easily produced from a phase comparison signal and the window pulse through a VFO circuit. A gate 10 transmits the CLP signal only when a high-speed filter is selected. A pulse width inspecting circuit 12 checks the pulse width of the CLP signal. The pulse width of the CLP signal is gradually reduced as the phase synchronizing process advances. When this width becomes less than a set level of the circuit 12, the output of the circuit 12 is kept at a low level. When this low level lasts longer than the time corresponding to M bytes, an M-byte detecting circuit 13 inverts its output to a high level and switches an LPF.

Title: Ventilating device for automobile
Inventor: SEKI HIDEYUKI
IPC: B60H1/26
Filed: 1986-05-30
Abstract: PURPOSE:To prevent dust and noise from entering an automobile room by opening and closing a valve body provided on a vehicle body being interlocked with a door, in a device in which a valve body provided on a ventilation port is opened to facilitate the closing action of said door when the inside pressure of an automobile room becomes high. CONSTITUTION:When a door 2 is opened centering around a rotatable supporting shaft 22, a valve body 3 is swung centering around a rotatable supporting shaft 17 via the engagement of the projection 23 of a supporting arm 21 which the second arm 31b of a supporting arm 31 provided on the valve body 3, to open the opening part 15a of a pillar 1. At this time, a spring 19 rides over a dead point and positioned on an upper part to keep the valve body 3 in an opened position. After that, when the door 2 is closed, the projection 23 is engaged with the first arm 31a of the supporting arm 31 to close the valve body 3. At this time, however, the opened condition of the valve body 3 is maintained until the spring 19 rides over the dead point and positioned on a lower part, thereby, allowing the pressure inside the automobile room to escape outside a body facilitating the closure of the door 2.

Abstract: PROBLEM TO BE SOLVED: To eliminate the need of a hole for putting a terminal through a power supply substrate circuit by providing a connecting member or the like between a housing member and the power supply substrate circuit regarding the power supply substrate circuit connected to a plurality of terminals and the connecting member or the like. SOLUTION: The length of a terminal 14a provided to penetrate a substrate 4 is formed longer than that of a terminal 14b and a high frequency superposing circuit 50 connected to the end part of the terminal 14a is arranged on a plane farther than a flexible printed circuit board(FPC) 51 from the substrate 4. Thus, the large extension of the power supply circuit board or the FPC in the height direction H of an optical pickup is eliminated and the length in the height direction H of the optical pickup is shortened. Further, compared with the disposition of the FPC 51 farther than the high frequency superposing circuit board 50, since it is not necessary to provide a hole for passing the terminal 14b through the high frequency superposing circuit board 50, the use efficiency of the high frequency superposing circuit board 50 is improved and the device is miniaturized.

Title: Semiconductor printing aligner
Inventor: TSURUOKA YUJI
IPC: H01L21/30
Filed: 1989-05-22
Abstract: PURPOSE:To correct the variation with time of optical axis position of exposure light by receiving the exposure light, detecting the optical axis position of the exposure light, and correcting the optical axis position of the exposure light based on the detection results. CONSTITUTION:At the initial adjustment, the optical axis of laser is set so as to pass the center axis of a beam expander 2, and an excimer laser 1 is so fixed to an aligner main body that the optical axis of laser coincides with the optical axis of an optical system in the aligner main body. The position of the optical axis on an image sensor 4 is previously stored; the deviation amount of the optical axis from the above position is obtained with an image processor, based on the image information outputted by an image sensor 4 which always monitors the intensity distribution of laser beam, according to the deviation amount, the beam expander 2 is adequately moved in the X or Y direction; thus the laser light flux is subjected to parallel movement, thereby correcting the optical axis position. Hence the optical axis position of the incident laser beam with respect to the optical system in a printer main body can be stably kept at a specified position.

Title: Gate noise preventing circuit for thyristor
Inventor: ISHIDOU MICHIHARU
IPC: H02M1/08
Filed: 1977-10-21
Abstract: PURPOSE: To prevent the gate noise of SCR for the gate trigger pulse circuit in which the control circuit is insulated from the main circuit via the pulse transformer, by attenuating the normal trigger pulse regardless of the noise voltage.  
     CONSTITUTION: When transistor Q 1  is turned on, the gate tirgger current flows through element D 1  and by the secondary voltage of pulse transformer PT to turn on SCR 2 . After supply of sufficient amount of the gate current, Q 1  is turned off by signal sorece SG, and thus photo coupler PC is turned on with by-phass secured by Q 2  between the gate and the cathode of SCR 2 . In this way, the noise is all by-passed to Q 2  in the state under which no normal gate trigger exists, that is, when Q 1  is off even though the charge/discharge current may flow to inter-winding floating capacity C of PT by the fluctuation of the cathode potential of SCR 2 . As a result, the gate noise of SCR 2  can be prevented, thus avoiding the malfunction

Title: Prom protecting circuit for misinsertion of prom writer
Inventor: MIZUNO SAKUYUKI
IPC: G11C17/18
Filed: 1980-09-12
Abstract: PURPOSE:To facilitate an easy write-in/readout action to PROM and at the same time to prevent the breakdown due to a misinsertion of the PROM, by controlling the voltage to be supplied to the PROM and detecting the normal or abnormal insertion of the PROM into a socket through a comparator. CONSTITUTION:Transistors (TR) 3 and 2 are turned off since a voltage application signal 32 is set at OV excepting the write-in/readout mode. Then the voltage divided by a high resistance 1 and an internal resistance 7 of a PROM6 connected forward to a socket 4 is supplied to the PROM6. While the voltage passing through the resistance 1 is higher than the reference voltage, and the output of a comparator 5 is set at a low level. If the PROM6 is inserted backward into the socket 4, the resistance 7 is reduced. As a result, the output of the comparator 5 is inverted to a high level to produce an alarm through a buzzer 10, etc. In this case, both the voltage and current to be supplied to the PROM6 are controlled by the resistance 1 to prevent the destruction of the PROM6. Thus the write-in/readout to a PROM can be done in an easy and accurate way witout paying any excessive attention to the insertion of the PROM into a socket. At the same time, the breakdown of the PROM due to a misinsertion can be previously prevented.
