IPC: F16L37/20
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To prevent strong vibration or impact during working from removing a joint part, by attaching a toggle joint fitting to one side of fluid hoses which are interconnected through a rapid joint, and an engaging fitting with which the toggle joint fitting engages to the other side. SOLUTION: Toggle joint fittings 5 are attached to a joint part 4 fixed to a joint side hydraulic hose 2, and an engaging fitting 7 with which the toggle joint fittings 5 is engaged is attached to a jointed part 6 of jointed side hydraulic hose 3.

Title: Instantaneous water boiler
Inventor: SUMI SHIYOUJI
IPC: F23N5/18
Filed: 1983-08-26
Abstract: PURPOSE:To prevent the temperature of hot water lowering when supply of hot water is stopped and thereafter resupply of hot water is started by controlling to hold a blower for supplying combustion air in a burner as it is still in ON operation within a predetermined time after stopping the hot water supply. CONSTITUTION:A controller 18 controls the blower 7 to hold ON peration within a predetermined time after stopping the hot water supply. That is, since scavenging is carried out with a certain period of time even when the hot water supply is stopped as the blower 7 is driven, if a detection signal is emitted from a flow quantity switch 1 at the time of resupplying hot water, the ignition operation can be started regardless of time divisions T1 and T2. Simultaneously with the hot water resupply, the temperature of supply hot water increases at a time constant T3, and hence hot water of a desired temperature can be obtained with only a time delay of T3. Thus, even when the supply of hot water is stopped, the blower for supplying combustion air in the burner is kept being driven within a predetermined time, whereby the degree of lowering of the hot water temperature during the hot water supply can be reduced and hence comfortable use of hot water is made possible.

Title: Electromagnetic flowmeter
Inventor: KAYAMA NAGAOKI
IPC: G01F1/60
Filed: 1979-11-30
Abstract: PURPOSE: To obtain an electromagnetic flowmeter which is hard to be influenced by variation of power supply voltage and frequency, by dividing induced voltage of an electrode, which obtains output in accordance with flow rate of liquid, by a comparative voltage proportional to a current passing an excitation coil.  
     CONSTITUTION: A commercial power source 11 is connected to a full wave rectifying circuit 37 through a current rransformer 34, and it is further connected through a group of switches 45 to an excitation coil 17 which is arranged perpendicularly to electrodes 21 and 22 in a pipe 19. And the output side of the current transformer 34 is full-wave rectified by a rectifying circuit 51, and the output is supplied to a resistor 53 through a group of switches 52. When the group of switches are controlled by a timing circuit 26 synchronized at a frequency lower than the commercial power source 11, the current passing in the resistor 53 becomes proportional to the current passing in the excitation coil, and therefore, when a voltage generated from the electrodes 21 and 22 is amplified 23 and divided 61 by comparison voltage of the resistor 53, it is possible to obtain a signal which is proportional to flow speed signal and not influenced by variation of power source voltage and frequency.

Filed: 1983-08-29
Abstract: PURPOSE:To prevent the shock when an upper rotary body is stopped by reversely controlling a variable pump to stop the upper rotary body when a construction machine turns and descends at a crawling speed and is stopped on a slope.

Abstract: PURPOSE:To obtain a reproduced picture with a less deterioration in pattern even when a video signal with bad S/N is recorded by providing a gate circuit, a timing pulse generator, a high pass filter, a detector and a control signal generator. CONSTITUTION:An input luminance signal 1 is given to a high pass filter 2, a variable gain amplifier 3, and amplitude limiter 4 and the result is added to the signal 1 by an adder 5 at recording. Only a signal during the horizontal synchronizing period is extracted by a gate circuit 10 and a high frequency noise component is extracted by a high pass filter 12. The high frequency noise component is detected by a detector 13, a control signal generator 14 is operated in response to the detection level to limit the gain of the amplifier 3 and the limiter 4. Thus, a minute signal and noise added to the signal 1 are increased/ decreased in response to the noise level. At reproduction, the gain is controlled in response to the detection output level similarly at recording via a timing pulse generator 11 at reproduction. Thus, even when the video signal with bad S/N is recorded, a reproduced picture with less pattern deterioration is obtained.

Title: Optical master disc and production thereof
Inventor: UENO FUMIAKI
IPC: G11B7/26
Filed: 1989-06-19
Abstract: PURPOSE:To prevent the generation of radial unequal coating by providing a region recessed from a region formed with V-grooves in contact with the region formed with the V-grooves so that a photoresist can be uniformly applied over the entire region formed with the V-grooves. CONSTITUTION:The V-grooves are formed by using a V-shaped cutting tool having a sharp pointed end on the master disc 3 consisting of a metal, such as copper. The master disc is subjected to the machining to recess the region in contact with the region 1 formed with the V-grooves and is carved in by about several tens micron after the V-grooves are formed. The depth of the carving-in is not of a particular problem even at about several microns. The uniform accumulation of the photoresist in this region is not possible and the effect of eliminating the unequal coating is not possible at the time of a final coating if the depth of the carving in is as shallow as several microns or below. Since the inner peripheral side of the region formed with the V-grooves is recessed from the region 2 formed with the V-grooves, the photoresist overflowing to the inner peripheral side at the time of the precoating accumulates uniformly at the boundary with the region 1 formed with the V-grooves and, therefore, the generation of the radial unequal coating is obviated.
