Title: Saturable reactor for high voltage pulse generator
Inventor: NAKAJIMA SUSUMU
IPC: H01F29/14
Filed: 1988-04-14
Abstract: PURPOSE:To prevent heat generation during operation, remove deformation of a magnetic core and always maintain a good magnetic characteristic by arranging an insulator band material of a holding material on the inner and outer peripheries of a saturable iron core and causing a cooling medium to flow therebetween. CONSTITUTION:The inner and outer peripheries of a ring-shaped saturable magnetic iron core 7 are held by the band-shaped insulating holding members 9a and 9b for being arranged between an inner tube and an outer tube of a double-wall cylindrical conductor. The double cylindrical conductor 1 has a function of a wiring, while an inner cylinder terminal and an outer cylinder terminal are selectively made an input terminal and an output terminal. The both ends of the double wall conductor are provided with an inflow hole 5 and an outflow hole 6 of a cooling medium in order to cool the saturable magnetic core of the cylinder conductor. The saturable magnetic core is so formed that a magnetic thin band is blanked in a ring for being laminated in a large number through the insulating layers. An amorphous thin band is favorable for improving a magnetic characteristic of the magnetic thin band and when this thin band is given a heat treatment before making the magnetic core, it is hard to heat during operation. When a saturable reactor according to this constitution is used for a high voltage pulse generation device, the device has a high output and change with the passage of time due to the deterioration of the magnetic core is prevented thereby obtaining a long life.

Title: Method of underwater starting pump
Inventor: OKADA MASAYASU
IPC: F04D15/00
Filed: 1978-07-26
Abstract: PURPOSE: To accomplish better underwater starting of pumps preventing the rise in the water temperature about the runner by feeding cooling water while draining hot water about the runner with the release of a guide vane, when the temperature reaches the preset upper limit.  
     CONSTITUTION: Given a underwater starting command, a runner rotates with a main shaft 1 by a motor 2 when a guide vane 7 and an oil feed valve 10 are fully closed. This raises the water temperature about the runner. When the water temperature reaches the upper limit, actuating an upper limit temperature relay in a heat indicator 2 to open an oil feed valve 10. Consequently, driven by a servo motor 9, the guide vane 7 is properly opened through a guide vane control mechanism 8. Thereupon, for example when the rotation speed of the runner 3 is low and the pressure about the runner 3 is low, a moderate amount of cooling water is fed into the area surrounding the runner 3 from a casing via a casing 6, while the hot water discharged into a draft tube 4.

Title: In-chamber temperature control method for cold air circulation type open shoe case
Inventor: AOYAMA YUJI
IPC: F25B1/00
Filed: 1989-04-10
Abstract: PURPOSE:To surely hold temperature in a chamber at a value within a range from a set upper limit to a set lower limit temperature by a method wherein solenoid valves to regulate circulation and the feed of a refrigerant to a cooler by means of a thermostat for detecting temperature in a chamber are provided on the inlet and the outlet side of the cooler to control temperature in the chamber. CONSTITUTION:When it is detected by a thermostat 9 that temperature in a chamber 4 is reduced to a lower limit, solenoid valves 15 and 16 are simultaneously closed, and a refrigerant in a cooler 7 is confined therein as it is. A compressor 11 rapidly reduces a pressure on the suction side, and a low pressure switch is actuated to immediately stop the compressor. Since the pressure of a refrigerant is not reduced, the cooler 7 does not heat-exchange with air in a chamber intended to be washed, and temperature in the chamber 4 is not reduced to a value lower than a lower limit temperature. When temperature in the chamber 4 is increased and it is detected by the thermostat 9 that temperature in the chamber is increased to an upper limit value, the solenoid valves 15 and 16 are simultaneously opened, and through running of the compressor 11, a refrigerant is circulated and fed to the cooler 7 again to cool the interior of the chamber 4.

Title: Extracting system of start point of vertical synchronizing signal
Inventor: FUJIWARA HISAO
IPC: H04N5/10
Filed: 1983-05-24
Abstract: PURPOSE:To extract a vertical synchronizing signal stably with a high precision by setting a time window about one field after the trailing edge of the just preceding vertical synchronizing signal and defining a point of time, when the level exceeds a threshold in this time window, as the start point of a vertical synchronizing signal. CONSTITUTION:A demodulated television signal 12 is divided into two; and when the trailing edge of a vertical synchronizing signal is detected by an extracting circuit 13 of the trailing edge of the vertical synchronizing signal, a one-field delay circuit 15 counts clocks inputted from a terminal 16 and outputs leading edge information 18 to a DC level clamping circuit 19 and a vertical synchronizing signal start point extracting circuit 21 after the elapse of a one-field time. When leading edge information 18 is inputted, the DC level clamping circuit 19 clamps it to 0V and outputs a clamp output 20. The vertical synchronizing signal start point extracting circuit 21 is set to the holding state when receiving leading edge information 18; and since the time window is set, the circuit 21 outputs a vertical synchronizing signal start point pulse 22 corresponding to a certain number of clocks when the clamp output 20 exceeds the threshold.

Abstract: PROBLEM TO BE SOLVED: To provide a noise reducing device in automobile component small in size, simple in structure, reduced in the number of components easy to manufacture, high in versatility and low in cost. SOLUTION: When a floor panel 2 is vibrated, a housing 4 of this noise reducing device 3 is also vibrated almost similarly to the floor panel 2, and an acceleration pickup 7 incorporated in the housing 4 detects vertical acceleration of the enclosure 4 vibrated with the floor panel 2, and outputs an signal to a generated sound control part 9. The generated sound control part 9 calculates a vibration signal (offset signal) to minimize the input signal and outputs it to a driving circuit 8. The driving circuit 8 outputs to a piezoelectric actuator 5 according to the input signal, and the piezoelectric actuator 5 is expanded and contracted based on the input signal and is also acted by a weight of the heavy bob 6 to apply a force on a vibration plane 4a of the housing 4 and generates damping (offset sound) vibrations.  Thus, the device eliminates the need for a loudspeaker and has a configuration comprising each component part collectively in the housing.
