Title: Distance meter
Inventor: KITAYAMA KENZO
IPC: G01S7/521
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption and size of a distance meter by connecting an ultrasonic vibrator to a piezoelectric element, adding impacts to the piezoelectric element and generating pulsing voltage, and constituting an ultrasonic generator which is not necessary for power source and transmission circuit. SOLUTION: A distance meter 100 is provided with a measuring part 102 having an LED display 21, a high voltage generator part 103 and a rod part 104 fixed by an oscillator part 6 at its tip end. The high voltage generator part 103 consists of a pushbutton 103a, a piezoelectric element and a hammer for hitting the piezoelectric element. When the pushbutton 103a is pushed, the hammer hits the piezoelectric element to add impact and a high voltage is generated between a lead wire and a fixing metal. If the piezoelectric element is hit by the hammer in the state the oscillator part 6 is submerged in sea water, high voltage pulse is generated and ultrasonic wave is emitted from the ultrasonic vibrator in the oscillator part 6 to the sea bottom. The echo from the sea bottom accompanying the wave emission is received with the ultrasonic vibrator.  Using the LED display 21 arranged with LEDs in line, the LED at the location corresponding to the measured depth is turned on.

Title: Combustible chaff changed so as to be combustible by changing characteristic of chaff and its production
Inventor: SUDA TAKEKO
IPC: C10L9/10
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To obtain combustible chaff changed so as to be combustible in order to effectively utilize chaff having water repelling property and being industrial waste-like material of rice bowl because of slow flammability and produce chaff fuel having good combustion efficiency as further rational use. SOLUTION: Melted wax is mixed with chaff to assimilate the wax with cuticular layer covering epidermis of chaff. As a result, solid membrane of wax-like substance of the cuticular layer gradually comes in close to a gas membrane and the surface tension is changed. Continuous film of the wax-like substance of the cuticular layer produces numerous pores by being affected by two-dimensional saturated vapor pressure generated in this time. The pores produced in the film play role of a vent hole. Further, melted wax, etc., are absorbed into chaff and when the chaff is burned, the chaff is burned as combustion medium and combustion efficiency is enhanced by synergistically making the wax act on combustion of chaff. The combustible chaff can be formed into rational chaff fuel. The chaff fuel burns without being inhibited by characteristics which chaff has.

IPC: H02K1/22
Filed: 1981-11-16
Abstract: PURPOSE:To lighten the weight of laminated sections except an end section in the axial direction while reducing mechanical loss, and to start a motor easily by forming notches to the steel plates of the laminated sections. CONSTITUTION:The yoke 1a is formed by laminating the torus-shaped steel plates, outer circumferential sections thereof have pigeon tail-shaped grooves 2 connected to a field pole and central sections thereof have inner holes 3 connected to a main shaft. Here, the notches such as cylindrical holes 7 are formed to the steel plates lc of the laminated sections except the steel plate 1b of the end section in the axial direction. Accordingly, the weight G of the yoke 1a is lightened, and a flywheel effect GD<2> is reduced. Since the notch 7 is not formed to the steel plate 1b of the end section in the axial direction, space penetrating in the axial direction is not shaped, thus reducing windage loss.

Title: Strobe electron beam device
Inventor: OKUBO KAZUO
IPC: H01L21/66
Filed: 1985-08-20
Abstract: PURPOSE:To enable high-speed scanning free from phase shift by dividing the frequency of a high frequency clock by a first and a second frequency-dividing circuit and varying the frequencies of two clock signals supplied to an IC driver and a strobe SEM. CONSTITUTION:A high frequency clock 101 from a high-frequency-basic-clock- generating circuit 1 is supplied to a first frequency-dividing circuit 2 for dividing in M portions and a second frequency-dividing circuit 3 for dividing in (M+L) portions and the outputs of the circuits 2 and 3 are delivered to an IC driver 5 and a strobe-SEM-controlling circuit 11. The phase of the basic clock applied to the strobe-SEM-controlling circuit 11 is adjusted to be slightly ahead of the phase of a clock applied to an IC driver 5 for each period. The phase shift caused during performing frequency scanning is prevented by synchronously producing the clock signal. Due to the above structure, it is possible to measure the waveform of the IC internal signal with high resolution by achieving high speed without using any delay line.

Title: Measurement of thermal resistance of integrated circuit chip
Inventor: FUJIWARA RIYOUZOU
IPC: H01L21/66
Filed: 1980-12-23
Abstract: PURPOSE:To calculate thermal resistance of a chip for integrated circuit from variation of the duty factor of wave form outputted before and after starting of operation  of the circuit by a method wherein the fact that heat generated in the IC chip makes  the threshold value of operation of the circuit to vary is utilized. CONSTITUTION:A triangular wave input signal 5 is applied to an input terminal 2, and an electric power source switch 4 is closed. The period TIN of repetition of pulse of  the triangular wave is constant. Pulses 6 of the period TIN having pulse width TS are outputted from a terminal 3, and the duty factor of the IC chip before generation of  heat is TS/TIN. During the interval in which generated heat at junction comes up to  reach the objective measuring part, heating is continued by input from an electric  power source 4. After heating is finished, pulse width TE is measured to calculate TE/ TIN. After heating is finished, the threshold value of operation of the circuit varies.  When the base line moves to the lower part, pulse width at the upper part of the base  line enlarges, and variation quantity of the duty factor becomes as to TE-TS/TIN, and thermal resistance of the chip can be decided when the relation between variation  quantity and actually generating heat is measured.

Filed: 1989-07-17
Abstract: PURPOSE:To quickly confirm the storage position of a medium by checking whether or not a conflict is recognized between the actual storage position of the medium set after a fault of a storage system is recovered and the storage position control data. CONSTITUTION:An automatic medium storage system monitors the working state of a system and collects the data on the start and end time points when a handling robot 3 carries a requested medium, the identification number of the medium, the positions of the carrying start and end points, etc. Before an automatic operation is started after the recovery of the fault, the robot 3 recognizes the medium kept under a carrying or recording/reproducing process at the occurrence of the fault via a recognizing part 101 for medium operated at the occurrence of fault. Then a medium storage position checking part 103 confirms whether the medium is kept in the robot 3, a recording/reproducing device 5, or a medium storage shelf 2 shown by the storage position data. If the conflict is recognized, the storage position of the medium is corrected by a medium storage position correcting part 104 as instructed by the corresponding data.
