Title: Radio transmitter and receiver
Inventor: KANOUDA KEIJI
IPC: H04B1/54
Filed: 1980-11-26
Abstract: PURPOSE:To make a radio transmitter and receiver small-size and reduce the number  of adjusted positions, by generating a transmission frequency signal by a direct oscillating variable frequency divider type synthesizer and by performing the frequency conversion of the transmission frequency signal to use it as a local oscillation frequency  signal at the receiving time. CONSTITUTION:At the transmission time, the oscillation signal from a voltage control  variable frequency oscillator 17 of a direct oscillating variable frequency divider type  synthesizer 16 is modulated by a sound signal which passes through a microphone 3  and a momentary frequency shift control circuit 4, and this modulated signal is amplified by a power amplifier 6 and is transmitted through an antenna 8. At the receiving  time, the output signal of the synthesizer 16 is subjected to frequency conversion by a  frequency converting circuit 23, and the output signal from the circuit 23 is used as a  local oscillation frequency to subject the receiving signal to frequency conversion in a  frequency converting circuit 10, and the sound signal is outputted to a speaker 15  through a demodulating circuit 26. Thus, only a reference quartz oscillator 21 for  transmission and a local oscillator 25 for receiving are used as quartz oscillators independently of the number of channels to reduce the number of adjusted positions, and  therefore, a device suitable for the radio transmitter and receiver for multiple channels  is obtained.

Title: Method and apparatus for detecting greasing condition in lubricant supply device
Inventor: MORI KATSUMI
IPC: F16N7/38
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To effectively detect the greasing condition or the clogging of a greasing valve by counting the number of times of pressure fluctuation in greasing, and comparing the counted number with the number of greasing valves to detect the existence of the clogging of greasing parts. SOLUTION: The lowering internal pressure in a greasing pipe 4 is detected as a first number of pressure fluctuation by a pressure sensor during the lubricant of high viscosity is supplied from a nipple connected to a greasing valve to a greasing part. The data is sent to a control part 6 to be counted. After the greasing of a first greasing valve is completed, the feed is interrupted. On the other hand, a greasing pump 1 is continuously operated, so that the internal pressure in the greasing pipe 4 is gradually recovered, and a second greasing valve is operated to execute the greasing to a second greasing part. The greasing operation is successively executed one by one, and the greasing pump 1 is stopped after the greasing operation of the final greasing valve is completed.  Then whether the counted number is agreed with the number of greasing valves, or not is checked. 'No-clogging' is judged when the numbers are agreed with each other, and 'clogging' in some valves is judged when the numbers are not agreed with each other.

Filed: 1980-11-28
Abstract: PURPOSE:To obtain sharp reproduced images of high light carrier generation efficiency by X-ray exposure by providing a layer of high absorptivity to irradiated X-rays on a conductor layer in combination with a photoconductor layer. CONSTITUTION:A Pbo layer 3 of superior X-ray absorption efficiency is formed on a conductor layer 1, and a photoconductive layer 2 of a Se layer 2 or the like is formed thereon, whereby an X-ray photoreceptor is made.

Filed: 1988-07-04
Abstract: PURPOSE:To prevent the generation of malfunction due to noise by controlling the oscillation frequency of an oscillator by a test mode set signal, detecting the transfer of frequency and sending a test mode switching signal. CONSTITUTION:The oscillation frequency of a pulse oscillator 1 to which a test mode setting signal 6 is inputted is transferred from a 1st oscillation frequency to a 2nd oscillation frequency.

Filed: 1980-11-28
Abstract: PURPOSE: To realize a wide dynamic range and a high efficiency, by supplying a high power source voltage to a power amplifying circuit for a constant time when the output of the power amplifying circuit exceeds a prescribed level.  
     CONSTITUTION: When the output level of a power amplifying circuit 3 exceeds a reference voltage V ref  of a comparator 50, the output of the comparator 50 becomes high-level. This signal is differentiated by a capacitor 54 and a resistance 55 and is inputted to an operational amplifier 60. Consequently, the output of the amplifier 60 becomes high-level, and by this output, a capacitor 73 is charged through resistances 70 and 71 and a diode 72. The amplifier 60 continues outputting the high level for a constant time until the capacitor 67 is charged, and the output is applied to a transistor TR81a to turn on the TR81a, and a TR82a is turned on next, and therefore, a high power source voltage VH is supplied to the power amplifier 3. When the amplifier 60 becomes low-level, a TR75 is turned on for a constant time by the capacitor 73 not to receive the output of the comparator 50.

IPC: G11B7/085
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To enhance the reading/writing rate of signal by inserting a detection resistor in series with a DC motor and feeding the voltage drop across the detection resistor positively to a drive circuit through a feedback amplifier. SOLUTION: A detection resistor Ro is inserted into a BTL system drive circuit in series with a motor 1, and the voltage drop across the detection resistor is partially fed back positively to the antiphase input terminal (-) of an operational amplifier 3, through a feedback amplifier 4. Consequently, the voltage Vout varies by a current Ia flowing through the motor 1, and the r.p.m. of the motor 1 can be controlled by a control voltage being inputted to an input terminal 5. Furthermore, a target r.p.m. can be reached more quickly. Consequently, the signal reading/writing rate of an optical disc medium can be enhanced.
