IPC: C10L5/00
Filed: 1980-08-12
Abstract: PURPOSE: To remove ash, etc., from pulverized coal by a method in which a liquid layer is formed on a shelf plate by flowing down an aqueous coal slurry onto the shelf plate, and the aqueous coal slurry is continuously washed by small power by dipping a supersonic vibration unit in the liquid layer part.  
     CONSTITUTION: An aqueous coal slurry is flowed down onto a shelf plate 11 held nearly horizontally to form the liquid layer part of a constant water level, and a supersonic vibration unit 22 is provided above the liquid layer part so that the lower part of the supersonic vibration unit 22 is dipped in the liquid layer part. Thus, when a supersonic vibration is directly applied to the aqueous coal slurry, the pulverized coal can be cleaned with consumption of small amounts of power and inorganic impurity minerals, e.g., ash, sulfur, etc., can be removed.

Abstract: PURPOSE: To reduce cost only with a hole bored in a handle by forming a recessed area or a projected area on the rear side of a ceiling of a machine room and installing an opening area to a cover which covers the machine room so that the recessed area or the projected area may be hooked with a finger. CONSTITUTION: A condenser 8 emits the heat of high temperature refrigerants discharged from a compressor 6 while the heat dissipated from the compressor 6 and the condenser 8 is emitted outside the machine room from an opening area 4. The opening area 4 is formed on a machine room cover 3. During transportation time, a hand is inserted into the opening 4, thereby lifting up a bottom plate and lifting up a refrigerator. At that time, a finger tip is hooked at the position from 20 to 60mm distant from the opening area 4. If the recessed part is installed in size which ranges from 5mm to 15mm high and from 10mm to 30mm deep, it will be convenient to carry since force is easy to be applied to the recessed part.  The upper end face of the opening 4 is substantially flush with the surface where the recessed part 12 of the bottom plate 5 is formed while the opening dimension of the opening area 4 is such that hand may be applied to the recessed part 12 easily.

Abstract: PURPOSE:To reduce power consumption, by connecting a level shifting element between a power source and the source of the P channel MIS transistor (TR) of an input inverter formed by connecting the P channel MIS-TR and an N channel MIS-TR in series. CONSTITUTION:A chip selection signal input part consists of the 1st stage inverter INV1 to which an external control signal -CS is inputted a P channel MISQ7 between it and the power source, the 2nd stage inverter INV2, and a P channel MISQ10 between it and the power source. The 1st stage inverter is constituted by connecting the P channel MISQ5 and N channel MISQ6 in series. The drain voltage of the Q5 drops below Vcc by the threshold voltage of the MISQ7 through the operation of the MISQ7, so the voltage range of the signal -CS is narrowed down. Consequently, the power consumption of the chip signal input part in still operation is reduced.

IPC: G11B9/06
Filed: 1982-06-28
Abstract: PURPOSE:To pick up and reproduce the recorded FM signals with high fidelity for a pickup circuit of electrostatic capacity system, by providing an isolator in a direction where the signal transmitted to an oscillator from a resonance circuit is absorbed. CONSTITUTION:The oscillating signal given from an oscillator 4 is supplied to a resonance circuit 3 by a coupling coil 5 through an isolator 10. The FM signal recorded on a disk is picked up by a pickup coil 6. The change of resonance frequency of the circuit 3 due to a capacity change on a disk is cut off by the isolator 10 to give no effect to the oscillator 4. Therefore the oscillating frequency f0 of the oscillator 4 has no change. Thus the oscillator 4 has an extremely stable operation. This assures reproduction of the FM signals recorded on a disk with high fidelity.

Title: Camera capable of recording information
Inventor: WATABE TAKESHI
IPC: G03B17/24
Filed: 1996-05-07
Abstract: PROBLEM TO BE SOLVED: To prevent a failure that needless information is inadvertently recorded by automatically releasing an information recording mode for recording information other than a subject image on film according to time count output from a clock. SOLUTION: A control circuit 3 is constituted of a microcomputer and its peripheral parts and controls a recording device 4 based on a title set by a title setting device 1 and the time count output from the clock 2. The microcomputer of the control circuit 3 executes interruption processing when a date is changed in the clock 2. Namely, whether a title write-in mode is set by the setting device 1 is confirmed, and the title write-in mode is automatically released when it is set. In the case the title setting mode is not set, the interruption processing is finished. Thus, the set title write-in mode is automatically released when the date is changed.
