Abstract: PROBLEM TO BE SOLVED: To provide a density of a specific value or above and to improve durability by overlapping ceramic powder and metal powder having melting points of specific values or above, and connecting, molding and sintering them at a high temperature and a high pressure of specific values or above. SOLUTION: Ceramic powder and metal powder having melting points exceeding 2500 deg.C and 2000 deg.C respectively are molded and sintered at the density of 96% or above of the theoretical density under the same conditions as the sintering conditions of diamond, a high temperature of 2000 deg.C or above and a high pressure of 100 MPa or above. A ceramic having a high melting point, a high electron emission capability and low heat conductivity, e.g. LaB6, HfC or HfN, is used at the tip section of a thermoelectron emitting electrode. The remaining section slightly apart from it is made a heat radiation section constituted of a metal having a low thermoelectron emission capability and high heat conductivity, e.g. Ir, Os, W, Ta, Mo or Re. A molded and sintered body provided with the mixed powder of the ceramic powder and metal powder having different thermal expansion coefficients is preferably used, and the shearing stress generated on the faying boundary face at the time of natural cooling is mitigated.

Title: Pcm signal recording and regenerating apparatus and pcm signal regenerating apparatus
Inventor: OKAMOTO HIROO
IPC: G11B20/10
Filed: 1990-11-22
Abstract: PURPOSE:To make it possible to generate all required reference clocks with the minimum number of oscillation circuits by dividing the frequency of the first clock which is outputted form an oscillation circuit, using the frequency-divided signal as a reference, and generating and outputting the second clock having the frequency that is the integer times as high as the sampling frequency of the PCM signal. CONSTITUTION:An oscillating circuit 5 generates and outputs the first clock having the frequency that is the integer times of a channel frequency. Thus the reference clock is obtained. Frequency dividing circuits 8 and 13 divide the frequency of the first clock and output the frequency divided signals which are proportional to the sampling frequency of a PCM signal. When an analog input 2 is recorded or regenerated, a PLL circuit 26 generates and outputs the second clock having the frequency that is the integer times as high as the sampling frequency of the PCM signal with the divided frequency signal as the reference. When a digital input 1 is recorded, the PLL circuit generates and outputs the second clock with the digital-audio interface signal as the reference. Thus, all the required reference clocks can be generated with one oscillating circuit, the frequency dividing circuits and the PLL circuit.

Title: Vacuum cleaner
Inventor: OMOTO SHUHEI
IPC: A47L9/28
Filed: 1991-11-29
Abstract: PURPOSE:To provide a vacuum cleaner which can prevent overcurrent of a motor while improving operability. CONSTITUTION:When a potential on the non-inversion input terminal side of an operational amplifier OP3 becomes higher than a G point potential on the inversion input side as current flowing through a motor 12 increases, the operational amplifier turns to a non-inversion output. An operational amplifier OP5 and an operational amplifier OP2 are switched over to an inversion output and an OR circuit OR2 performs a pulse outputting based on an output from an output terminal of the operational amplifier OP4. The output of the motor 12 is lowered based on the output of the operational amplifier OP4. When the operational amplifier OP5 turns to a non-inversion output, an inverter circuit inv5 performs an H level outputting to store an electric charge in a capacitor C3 of a timer means 24. As the electric charge of the capacitor C3 rises with the passage of a specified time and an operational amplifier OP6 turns to the non-inversion output, a thyrister Th1 is turned ON and either of an AND circuit AND1 and an AND circuit AND2 moves to an L level output to stop the motor 12.

Abstract: PURPOSE: To establish one identical driving speed by installing input gears, capable of using selectively a first driving speed and a second driving speed different therefrom and generating the same output peripheral surface driving speed from the two and also installing output gears to mesh with the input gears. CONSTITUTION: In order to operate a pump by a gear transmission device 16 at one typical speed when the drive input is 1500 rpm, a gear device needs to be configured with eighty-one input gears 86, sixty-eight transmitting gears 124 and 130, sixty-seven output gears 126 and 128, and one hundred and fifty one output gears 132 and 134. Accordingly, the transmission gear turns at 1,786 rpm, and the peripheral surface speed becomes such as to rotate the output gears 126, 132, 128, 134 at 1,813 rpm and 804 rpm, respectively. When the drive input is at 1,800 rpm, there are sixty seven input gears 140, and the transmission gear rotates at 1,778 rpm, and the peripheral surface speed becomes such as to rotate the output gears 126, 132, 128, 134 at 1,802 rpm and 800 rpm, respectively.  Whichever power source is used, therefore, the peripheral surface speed to the output gears will substantially rotate the output gears at one identical speed.

Title: Multibeam positioning controller
Inventor: MIZUKAMI MAKOTO
IPC: G11B7/085
Filed: 1991-12-02
Abstract: PURPOSE:To evade the mutual interference of respective control operations, to stabilize the respective control operations and to position a multibeam at high speed by starting the control operation of a rotary driving part after starting the control operation of a parallel driving part. CONSTITUTION:A level comparator 21 compares an absolute value level (¦X¦) of a parallel error signal with a reference voltage (X0) and when the absolute value level of the parallel error signal is lower than the reference voltage, a parallel converging signal is outputted. An analog switch 11 is turned on by starting a start control signal imparted from the outside, and an analog switch 12 is turned on after parallel control is converged by interposing an AND gate 22 to validize the start control signal by a parallel control converging signal. Since timing to start the rotary control operation can be optimumly controlled in this case, the positioning control time of the mutibeam can be minimized.
