Title: Recording and reproducing device of optical information
Inventor: SATOU ISAO
IPC: G11B7/004
Filed: 1982-08-18
Abstract: PURPOSE:To perform reading of only a sector where the information is written correctly, by discriminating assuredly a sector where the recording is incomplete which is generated with a track jump under recording and a sector where the double writing is carried out for replacement from a normal data where the data is already written. CONSTITUTION:A preamplifier is equal to an AC amplifier is an envelope detecting circuit, and therefore the low frequency component is assuredly suppressed by an HPF20 for a signal 100 which lost its DC component. An envelope curve wave detecting circuit 22 detects the envelope signal 103 after a clamping circuit 21 had a DC reproduction in order to increase the signal level of envelope detection. A comparator output 104 is applied to a counter 25, and clocks 106 of a clock generating circuit 26 are counted. The output 107 of the counter 25 is set at one with a prescribed count number of clocks. Then a latch 27 is set at one. The envelope detecting signal 105 is not delivered at a sector where the double writing is carried out. Therefore it is possible to discriminate a normal recorded sector where the signal 105 is delivered.

Abstract: PURPOSE: To prevent derailment and the like by continuously arranging a transmitting lever transmitting displacement of a detecting body in the detecting body arranged in the front part beyond a wheel of a car washing machine, bringing the transmitting lever into contact with an obstruction on a traveling rail so as to detect displacement of the detecting body by means of a switch, and stopping a car washing machine from traveling. CONSTITUTION: A car washing machine 8 travels on a traveling rail 7 via traveling wheel 17, and a rotary encoder 15 detecting a traveling position is connected to an output shaft in a traveling motor 16 so as to output a pulse signal while detecting its rotational direction, so that the traveling position of the car washing machine 8 is detected. A transmitting lever 1 is arranged in the lower part of the car washing machine 8, while a switch operation unit 4 made of a magnetic body is arranged in the upper end part, and a switch 5 transmitting/stopping electric current to the traveling motor 16 is arranged in front of the switch operation unit 4. The switch 5 is arranged at a ground height of 60 cm or more so as to prevent taking fire and the like.  When an angle member 6 in the lower part of the transmitting lever 1 is brought into contact with an obstruction on the traveling rail 7, the transmitting lever 1 is inclined against energization of a spring 3 so as to carry out opening/closing control of the switch 5 for the traveling motor 16.

Title: Optical character reader
Inventor: WATANABE HIDEO
IPC: G06K9/20
Filed: 1985-07-02
Abstract: PURPOSE:To increase the form reading speed by dividing a form feed mechanism into three blocks to which independent drive sources are provided and controlling the feed speed of each block based on the information obtained by a sensor which detects the presence or absence of a form. CONSTITUTION:A form 1-1 is carried by the 1st feed part 2 and the characters written on the form 1-1 are read. When the tip of the form 1-1 is detected by a sensor 9, the 1st and 2nd feed parts 2 and 3 are synchronous with each other to carry the form 1-1. When a sensor 10 detects the tip of the form 1-1, the 1st-3rd feed parts 2, 3 and 4 are synchronous with each other for feed of the form 1-1. When the rear end of the form 1-1 passes through the sensor 9, both parts 3 and 4 are driven at a high speed to eject the read form 1-1 to a stacker 12. Then the speed of the part 3 is set at the speed of the part 2 when the rear end of the form 1-1 which is under ejection passes through the sensor 10.

Title: Disc brake device for vehicle
Inventor: YAMAZAKI GORO
IPC: F16D65/28
Filed: 1986-06-20
Abstract: PURPOSE:To improve the brake effect while simultaneously increase the freedom of space layout and to facilitate the piping work, by arranging primary and secondary calipers onto a brake disc provided at one side of a wheel. CONSTITUTION:When a brake lever 7 is operated to feed a pressure liquid produced in a primary master cylinder 6 to a primary caliper 5, a brake disc 3 is pressure held thus performing the brake function. Here, the primary caliper 5 is rotated by the brake torque so as to push the piston 11 in a secondary master cylinder 10 thus producing a pressure liquid which is fed through a secondary brake hose 15 to a secondary caliper 9, thereby the brake disc 3 is pressure held by the secondary caliper 9 thus performing the brake function. Consequently, the brake effect is improved while simultaneously the freedom of space layout is increased because the brake disc 3 is arranged at one side of a wheel, thereby a secondary brake hose can be shortened and the piping work is facilitated and the loss of pressure liquid being fed to the secondary caliper 9 can be reduced.

IPC: G01N27/42
Filed: 1983-08-09
Abstract: PURPOSE:To enable detection of humidity in gas by utilizing the electrolysis of water with high accuracy over a wide humidity range by setting a humidity sensitive element which is formed by joining directly an electrode catalyst to one or both surfaces of a high polymer solid electrolyte film permitting migration of hydrogen ion into the gas and impressing a set DC voltage to the joint body thereof. CONSTITUTION:A humidity sensitive element 1 is directly united and joined with a high polymer solid electrolyte film 2 and electrode layers 3, 4 as gas-permeable electrode catalysts on both surfaces thereof to form a joint body 5. An anode terminal 6 and a cathode terminal 7 which impress a DC voltage to the body 5 are likewise united and joined to one body thereto. The film 2 may be an H<+> ion conductor; for example, commercially marketed ''Nafion 117'' is used for the film 2 and rhodium as the layers 3, 4 are joined to both surfaces of the film. Such body 5 is cut to form the element 1. Platinum wires are then press-welded as terminals to both surfaces of the element 1. If a response speed is measured by using such element at the humidity varied to 30%, 60% and 90%, 90% change rate is attained within several minutes and the perfect equil. value is attained within 10min. The hysteresis is within several %.

Title: Ab class push-pull driving circuit, its driving method and ab class electronic circuit
Inventor: YAMASHITA KAZUO
IPC: H03F3/30
Filed: 1994-06-27
Abstract: PURPOSE:To attain an AB class push-pull driving circuit capable of increasing output amplitude, improved in symmetric property, hardly generating abnormal oscillation, and stabilized in temperature. CONSTITUTION:The emitters of npn transistors(TRs) Q1, Q2 and pnp TRs Q3, Q4 are connected in common. The inter-base voltages between the TRs Q1, Q3 and between the TRs Q2, Q4 are held at fixed levels respectively by constant voltage circuits 1, 2. Differential input voltage Vi is impressed between the bases of the TRs Q1, Q2. Collector currents I1, I3 and I2, I4 are respectively exponential-functionally and differentially increased/decreased. An AB class driving current is obtained through inverted addition of the currents I1, I3 or I2, I4. Since a route difference relating to signal amplification is not generated, an inter-route phase difference at high frequency is hardly generated. Abnormal oscillation also is hardly generated because there is no feedback or the like for AB class operation. Since the constant voltage circuits 1, 2 are constituted of diodes D1 to D4, the temperature characteristics of the TRs Q1 to Q4 are compensated. In addition, low voltage driving also is made possible. It is also attained by using FETs.
