Title: Peak detecting circuit for magnetic storage device
Inventor: YAMASHITA MITSUNORI
IPC: G11B5/09
Filed: 1990-06-19
Abstract: PURPOSE:To prevent the reduction of the degree of margin of read operation by changing the delay time of an output signal at the time of the occurrence of timing deviation of the output signal of a comparator which detects the zero-crossing point of a differential signal. CONSTITUTION:If waveform distortion 1a occurs in the reproduced signal by some cause, waveform distortion occurs in output signals 11 and 12 also, and positions of their zero-crossing points are shifted. Consequently, a peak pulse 3 is made asymmetrical only in the time difference between the high level part and the low level part of a pulse signal 41, and simultaneously, a control signal 61 outputted from a phase comparator 60 goes to a positive potential to extend the delay time of a variable delay element 30. Thus, the generated peak pulse is restored to a symmetrical waveform, and the reduction of the degree of margin of read operation due to deviation of the recording timing of a write current, distortion of the waveform caused by an influence of an external magnetic field, magnetization of a recording and reproducing head, or the like is prevented.

Title: Reader for boarding pass
Inventor: ONO YOSHIAKI
IPC: G06K13/06
Filed: 1989-06-22
Abstract: PURPOSE:To read a boarding pass by automatically correcting to normal posture even when it is inserted at any posture by separating the boarding pass from a travel route when it is set at prescribed detecting posture, and recovering it to the travel route by changing its direction. CONSTITUTION:When the boarding pass is inserted, the posture of it is detected with a posture detecting means 30. When it is judged that the boarding pass is inserted at the prescribed posture, the pass is separated from the travel route 21 in the half way of the travel route 21 with a separating means 40. Furthermore, the direction of the boarding pass is changed with a direction changing means 50, and after that, it is recovered to the travel route 21 with a recovery means 70. Thereby, it is possible to read the boarding pass by automatically correcting to the normal posture even when it is inserted at any posture.

Title: Flow rate control apparatus
Inventor: KOJIMA TADASHI
IPC: F16K31/06
Filed: 1980-11-14
Abstract: PURPOSE: To make it possible to control the flow rate of a fluid accurately through an electrical signal by a method wherein the operations of an ON-OFF controller and a proportional controller are controlled by a fluid pressure in a pressure chamber due to the action of an electromagnetic pressure supply apparatus.  
     CONSTITUTION: When the pressure in a second chamber 8 rises up to a first set value due to the action of an electromagnetic pump 2, a responsive member 13 is displaced to a predetermined position to move a first valve 24 away from a second valve 25 so that a gas within a communication passage 20 flows through a gap between the two valves into an outlet passage 28 at a limited flow rate. Further, when the pressure in the second chamber 8 increases higher than the first set value, the responsive member 13 and a rod 23 lowers further and the second valve 25 is lowered to move away from a valve sheet 29 by the engagement of the responsive member 13 with an engaging section 23a so that the gas flows into the outlet passage 28 at a rate proportional to the degree of opening between the valve 25 and the valve sheet 29.

Title: Switched capacitor filter
Inventor: KATOU SEIJI
IPC: H03H19/00
Filed: 1980-11-14
Abstract: PURPOSE:To obtain an output signal in phase with an input with a simple constitution, by inputting the input signal to a negative input terminal of an integrator via a switched capacitor. CONSTITUTION:The relation between a switched capacitor and a resistor is expressed as K4CB=T/R4 and K2CB=T/R2 (where T is the sampling period). That is, the resistor R4 correspons to the K4CB and the resistor R2 corresponds to the K2CB. An input signal is divided by resistors Ra, Rb and inputted to a positive input terminal of an operational amplifier 5. Further, a part of the same input signal is inputted to a inverting input terminal of the operational amplifier 5. Equation 5 (where S=jomega) is obtained by obtaining an output voltage V2. The principle of this invention is that the 6th term (integration) is cancelled by the 4th term to obtain the 5th term of inphase output which is a multiple of input voltage inputted from a noninverting input terminal of the operational amplifier. The integration or a multiple of the inputted voltage from the inverting input terminal of the operational amplifier 5 is the same as conventional value.

Title: Solar battery
Inventor: SUGANO MASAHIDE
IPC: H01L31/04
Filed: 1981-10-07
Abstract: PURPOSE:To eliminate current leakage resulting from P-N junction and to obtain a large photo response characteristic by providing an oxide film between the semiconductor thin film and semiconductor substrate at the light sensible surface. CONSTITUTION:An oxide film 32 is formed on the P type single crystal Si substrate 1. The N type polycrystal Si film 42 is then formed over the layer 32. Thereafter the electrodes 3, 4 are formed on both front and rear sides. When the electron and hole pair excited and generated by the light beam within the substrate 1 moves in the direction to the film 32 by the diffusion, the hole receives a force in the direction as becoming far from the film 32 due to a bending of energy band in the vicinity of film 32, while electron receives a force in the direction as becoming near to the film 32. Therefore, the electron and hole are isolated and the hole remains in the substrate 1 while the electron moves to the film 32. The film 32 is very thin and the electron having reached the vicinity of film 32 passes easily through the film 32 and reaches the film 42. The electron and hole pair generated in the substrate 1 in the above process is converged as the carrier. The electron and hole pair generated in the film 42 is also converged as the carrier by the similar process.

Filed: 1989-06-24
Abstract: PURPOSE:To duty-drive loads independent of the distortion of a power waveform by means of simple constitution by permitting a duty setting means to previously decide the conduction or interruption period of switching means. CONSTITUTION:The switching means 15r-15t are connected in series to the loads 13r-13t and a driving source 14. A switching control signal switching the conduction or interruption state of the switching means 15r-15t is given from a switching control signal generation means 16 and accordingly the switching means 15r-15t drive the loads. The duty setting means 17 is provided in the seitching control signal generation means 16, and the period of the conduction or interruption of the switching means 15r-15t is previously set. Consequently, the loads 13r-13t are duty-driven by switching the state of the conduction or interruption of the switching means 15r-15t in accordance with a duty rate which the duty setting means 17 sets. Thus, the loads 13r-13t can be driven at the previously decided duty rate with simple constitution.
