Title: Prom processor
Inventor: NAKAMURA SHIGERU
IPC: G06F21/10
Filed: 1991-04-11
Abstract: PURPOSE:To prevent the copy of a PROM for a PROM processor which performs the prescribed processing with use of a PROM where a program or the data are previously written. CONSTITUTION:The same identification code is previously written in a fixed area out of a memory area of a PROM 2 and a prescribed area in the memory area respectively. When the due processing is started, the identification codes are read out of the fixed area and the memory area of the PROM 2. Then the subsequent processing is inhibited if unmatch is secured between both identification codes. In regard of a PROM of the copied side, the identification code written previously in the fixed area out of the memory area is usually unmatched with the identification code copied in the memory area. Therefore the copied PROM is invalid.

Title: Single wire spiral antenna
Inventor: NAKANO HISAMATSU
IPC: H01Q7/00
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To reduce a wind receiving area and to tilt a circularly polarized radiation beam to reduce an installation height by making a spiral antenna arranged above a ground plane by a prescribed interval with a single wire and specifying the circumferential length of the spiral. SOLUTION: The single wire spiral antenna is arranged apart from a ground plane 2 at an interval (h) so that the antenna face is in parallel with the plane 2. The circumferential length C of the spiral of the antenna 1 is selected to be between 2λ and 3λ(λ is a quantity with respect to the operating frequency) and the interval (h) is selected to be nearly 1/4λ. Since a beam is tilted in the elevating angle direction, the elevating angle direction of the beam is set in the direction of communication resulting that the antenna 1 is installed on a horizontal plane. Thus, the installation height of the antenna 1 whose beam is directed in a desired direction is lowered and the wind receiving area is reduced and excess of the transportation limit is prevented even when the antenna is mounted on a mobile body.

Title: Combustion controller
Inventor: SHIBAYAMA MASAHIKO
IPC: F23N3/08
Filed: 1985-04-15
Abstract: PURPOSE:To avoid explosion sound caused by a residual unburned gas and discharge hot water in the early stage by providing a rotational speed detection means for the rotational speed of a fan and a suppression means which suppresses prepurge action when the detected rotational speed is in excess of a special rotational speed which is set lower than a lowest rotational speed in driving. CONSTITUTION:When starting discharge of the hot water,, it is judged by a water flow sensor 1 whether the rotational speed of a fan 7 is over a specified rotational speed. If it is over the specified speed, a gas for combustion is supplied from a combustion circuit 9 without prepurging action and at the same time the combustion gas is fired by an ignitor 15 and the fan 7 is rotated at a specified speed to supply the air for combustion in order to obtain a specified air-fuel ratio. When it is judged that the rotational speed of the fan 7 has not reached a special rotational speed, the prepurge action performed is, and after the prepurge is finished, the rotational speed of the fan 7 is shifted. Accordingly the fan 7 is rotating by its inertia and if its speed is over a special speed which is enough to exhaust the unburned gas, the prepurge is not made and the combustion is started at once to reach early a specified temperature in the hot water.

Abstract: PURPOSE:To simultaneously control the position and the speed of a DC motor only by a signal from an encoder without using a tachometer generator by conducting a logic operation by the detection signal and the position instruction signal from an encoder and a speed instruction signal. CONSTITUTION:The signal from an encoder 3 provided at a DC motor 1 and the position instruction signal from an instruction unit 7 are logically calculated in a logic circuit 8, which thereupon generates a position drive signal to control through  a DA converter 9, an AV converter 10 and a drive circuit 21 transistors Tr1-Tr4. The signal from the encoder 3 and the speed instruction signal from the instruction unit 7 are logically calculated in a logic circuit 12, which thereupon generates a speed drive signal to control through an FV converter 13 the transistors Tr1-Tr4 to thereby drive the motor 1. Since the position and speed of the motor are controlled only by the detection signal of the encoder 3 as described above, it can simplity the configuration without using a tachometer generator.

Title: Oscillator for radio communication equipment
Inventor: MIYAZAKI YOSHITO
IPC: H03B5/12
Filed: 1993-03-16
Abstract: PURPOSE:To obtain an oscillator for radio communication in which the rising time of oscillation is short by serially connecting the direct current corrector bias circuits of each oscillation circuit, buffering circuit, and switching circuit which turns on and off the currents of those circuits. CONSTITUTION:When an H level signal is applied to a switching terminal 64, a switching Tr 61 is turned on, and a power source is applied to an oscillation circuit 1. Then, the capacitors 21, 19, 15, and 17 for tuning, varactor diode 22 for tuning, and oscillator 20 of the circuit 1 are turned into an LS oscillation circuit, and oscillation is operated. Also, the capacity of the diode 22 is changed by a direct current voltage impressed to a frequency control terminal 25, and the oscillation frequency of the circuit 1 is changed. A buffer amplifier circuit 3 amplifies an oscillation signal from the circuit 1, and outputs it from an output terminal 39. On the other hand, when an L level signal is applied to the terminal 64, the oscillation is stopped, and the output from the terminal 39 is absent. A power supply terminal 4 has a direct current power source, so that discharging to each capacitor can be extremely reduced, and even when the H level signal is impressed to the terminal 64 again, charging to the capacitor can be operated in an extremely short time. Therefore, the rising of the oscillation can be attained in the short time.

Filed: 1979-06-26
Abstract: PURPOSE:To prevent a synchronization-disabled state by providing a circuit that inhibits alternate pulses in a string as many as a fixed number when starting an input signal or changing it over to another input signal. CONSTITUTION:This phase synchronizing circuit detects a phase difference between an input signal and an oscillation output fed back from voltage control oscillator VCO14 at phase comparing circuit 11, converts the phase difference into a voltage at phase voltage converting circuit 12, and then controls VCO14 with a signal obtained via filter 13 to obtain an oscillation output. In this phase synchronizing circuit, input signals X and Y are input to input switching circuit 10, which alternate signals X and Y with a switching signal. In this case, the output signal of circuit 10 is input to circuit 11 by way of input pulse inhibiting circuit 21. To synchronize the input signals with each other for the 1st time or to change a synchronizing input signal over to the other input signal simultaneously with synchronization, circuit 21 is controlled to inhibit alternate input pulses as many as a fixed number of them according to the properties of the input signal. Consequently, a synchronization-disabled state can completely be removed.
