Title: Measuring circuit for variable delay circuit
Inventor: IKA MASAO
IPC: G01R31/28
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To decrease the number of input circuits to be reduced as compared with the number of variable delay circuits at the time of confirming the operation thereof, which is difficult in prior art. SOLUTION: The measuring circuit for variable delay circuit comprises a variable delay circuit 1 including a lamp waveform generation circuit 5 and a reference voltage generation circuit 6, and a comparison circuit 2 including a comparator 3 with select function and a OR gate 4. A comparator 3 selected by a select signal SEL compares an internal reference voltage TEST0 with an external reference voltage ref and delivers the results to the OR gate 4 where the output from the comparators 3 are ORed and outputted to an external terminal TEST. If the potential is different between the TEST0 and the ref, a low or high level is outputted to the TEST otherwise an intermediate level is outputted. A comparators 3 not selected by the select signal SEL output a low level to the OR gate 4 regardless of the value of TEST0 and ref.

Title: Shelter type wiper
Inventor: MATSUOKA HIROSHI
IPC: B60S1/08
Filed: 1978-05-04
Abstract: PURPOSE: To simplify the wiper motor structure, to minimize it in size, and thereby to facilitate production thereof by arranging conductors and insulators on the surface of a rotary member so as to form a concave-convex surface, and thereby rotating a wiper motor in the reverse direction by bringing a brush into a sliding contact with the conductors.  
     CONSTITUTION: When a switch 3 is switched on, a wiper blade 1 rises from the stop position S up to an upper returning position U on the glass surface and then goes back up to a lower returning position D. This reciprocation of the blade 1 between the positions U and D is repeated hereafter. When the switch 3 is switched off, a wiper motor rotates in one direction and therefore the blade 1 reaches the position D. The power supply to the motor 4 is interruped at this time, but immediately restarted so as to rotate the motor 4 in the reverse direction. Then the blade 1 goes down up to the stop position S. A primary and a secondary brush which constitute a short-circuit switch are supplied with electric current by the convex part of a secondary electrode, and a body 7 is stopped abruptly due to the dynamic braking.

Title: Manufacture of semiconductor light-receiving device
Inventor: YAMAZAKI SUSUMU
IPC: H01L31/107
Filed: 1985-03-18
Abstract: PURPOSE:To utilize the liquid-phase growth deposition for obtaining a burying- type planar avalanche photodiode having InGaAs, InGaAsP and AlGaInAs layers as a light-absorbing layer and an AlInAs layer as a multiplication layer, by providing an InP intermediate layer on the AlInAs multiplication layer. CONSTITUTION:An N-type InP substrate 1 is provided thereon with an N-type InP buffer layer 2, an N-type InGaAs light-absorbing layer 3, an N-type InGaAsP layer 4 and an N-type InP layer 5. An N-type AlInAs multiplication layer 6 and an N-type InP intermediate layer 7 are further provided and selectively etched such that mesa-shaped multiplication and intermediate layers 6 and 7 are left in a light-receiving region. The superficial layers of the InP intermediate layer 7 and the InP layer 5 are melted back. An N-type InP layer 9 is formed by growth so as to bury the layered structure of the multiplication and intermediate layers 6 and 7. A P-type impurity such as Cd is diffused to form a P-type light-receiving section 10. Since the AlInAs multiplication layer 6 which has poor drapability with InP melt is covered with the InP intermediate layer 7, it allows the liquid phase growth of the InP burying layer 9 to be performed thereon. Thus, a planar structure can be obtained easily.

Title: Checkwriter
Inventor: SUGAI KAZUO
IPC: B41K3/62
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To form a character type composed of a varying pattern by digit and contrive the way to miniaturize a device and prevent a character type from being tampered with under a simple structure by indicating an amount in the character type composed of a non-compatible pattern excepting same digit by a printing means for printing paper to be printed such as a check. SOLUTION: If an amount is entered through a keyboard and an operating key for issuance is depressed, a control part selects between type wheels 51, 51... for number of digits and symbols which are entered, and selects a type 51a for a digit and a symbol by rotating the type wheels 51, 51... respectively to obtain the type 51a corresponding to all of the entered digits. In turn, the type wheel 51 is hammered at matter to be printed 10 on a printing block 53 to print a character type. As the character type is indicated in a varying pattern by digit, the angles of a striped pattern do not coincide with each other, if a part of the digit is only tampered with and also the digit is not matched with the pattern, if a part of the character type is only modified.  Consequently, the falsification of the printed paper is not successfully accomplished, unless the total character type is modified. Thus this method for preventing the falsification from being committed in effective.

Title: Horizontal synchronizing circuit
Inventor: SAITO MASAHISA
IPC: H04N5/12
Filed: 1991-02-26
Abstract: PURPOSE:To take stable synchronization by suppressing the fluctuation of a horizontal phase due to a temperature change or the like of the circuit. CONSTITUTION:A triangular wave generating circuit 13 generates a triangular wave (d) with an external horizontal synchronizing signal. A sample-and-hold circuit 24 uses an external horizontal synchronizing signal to sample the triangular wave (d). A sample-and-hold circuit 14 uses the horizontal synchronizing signal generated in the inside to sample the triangular wave (d). A differential amplifier/band limiter 15 generates a control signal by which a voltage controlled oscillator 16 is controlled based on the two sampling voltages. The control signal is not fluctuated due to a temperature change or the like and then the phase of the voltage controlled oscillator 16 is unchanged.

Title: Latent heat type heat accumulator
Inventor: ISHII TAKAHITO
IPC: F28D20/02
Filed: 1983-03-29
Abstract: PURPOSE:To prevent a reduction in the heat exchanging performance of a radiator due to a temperature reduction in the upper part of a heat accumulating material so as to obtain a high and stable heat exchange output as well as an enhanced rate of heat accumulation in a latent heat type heat accumulator which accumulates the thermal energy such as the solar heat and waste heat for use in hot water supply, air conditioning and heating. CONSTITUTION:A container 5 contains in it a latent heat type heat accumulating material 6 such as sodium acetate trihydrate, a heat conductive medium 7 which is almost insoluble to the heat accumulating material 6 and is gasified from liquid by absorbing heat and is liquefied from gas by releasing heat, for instance from gas-113, and an inorganic material 8 such as powdered Al2O2 which is moistened better by the sodium acetate trihydrate 6 than the flon gas-113 (7) with a remaining space D. The heat release is effected when cold water 9 passes through a radiator 10. Then, the vapor 7a of flon gas-113(7) in the space D releases the latent heat of vaporization on the pipe wall of the radiator 10 to become the condensate 7b. The cold water 9 is heated by the aforementioned latent heat of vaporization of flon gas-113(7). The condensate 7b of flon gas-113(7) drops into a space E for crystals 6a and melt 6b of sodium acetate trihydrate 6, and receives there a latent heat of melting of the melt 6b to become the gaseous form which evaporates into the space D.
