Title: Rotary shaft water sealing device for hydraulic machinery
Inventor: FUJIWARA TETSUO
IPC: F16J15/40
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To display sufficient water sealing capacity and prevent abnormal increase of wear quantity of segment type packing and the generation of network cracks or the like to a sliding rotary shaft sleeve without increasing the constitution of a rotary shaft water sealing device having the segment type packing with one or several feed water grooves and with feed water pressure or sealing water pressure of 2.45 MPa or more. SOLUTION: Segment type packing 1b is arranged around a rotary shaft 13, in conformity to ring shape, and pressure water is fed to a feed water groove from the outside. The rotary shaft 13 and the packing 1b are then slided to seal pressure water in hydraulic machinery. In such a rotary shaft water sealing device for hydraulic machinery, the thickness of the packing 1b is so set that the ratio of the value, obtained by multiplying higher water pressure between sealed water pressure in the machinery and feed water pressure by the seal width L of the packing 1b, to the value obtained by subtracting feed water groove width (k) from the thickness T of the packing 1b is 0.612:1 or less.

Title: Method and equipment for measuring distance
Inventor: TORIGOE MASAYUKI
IPC: G01B11/00
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To measure a distance to a measuring object in a short processing time without depending on a state of reflection on the surface of the measuring object. SOLUTION: A pulse light is cast on an object and a reflected pulse light therefrom is received at a prescribed position. At this time, the number of pulses of the reflected pulse light received within a prescribed time does not change according to a state of reflection on the surface of the object, but changes in accordance with a distance between an emitting part of the pulse light and the surface of the object. For instance, the number of pulses of a far measuring point is 1 and that of a near measuring point is 10. Accordingly, a readout strength for one reflected pulse from the object is made fixed by using a space light modulating element and the quantity of light read out from a modulating part of this space light modulating element is stored in an image sensing element.  The information on the distance to the object is obtained on a real time basis from a value of the quantity of the readout light stored in the element.

Title: Controller for three-phase ac power supply apparatus
Inventor: ISHIMOTO YOSHINORI
IPC: H02J9/06
Filed: 1991-05-17
Abstract: PURPOSE:To perform stably a mutual switchover in the three-phase AC power supply apparatus comprising a three-phase AC power supply and an inverter, whereby a three-phase AC output is obtained. CONSTITUTION:One of the line voltages of a three-phase AC power supply 1 is sensed by a single-phase transformer 8. The pulse corresponding to the output voltage of the transformer 8 and the pulse corresponding to the output voltage of an inverter 2, which is opposed to the sensed line voltage, are inputted to a microcomputer 9. The initial value of a down-counter 10, which corresponds to the phase difference and the frequency difference between both inputted pulses, is set by the microcomputer 9, and the down-counter 10 down- counts until the initial value becomes zero. Then, the clock pulse whose period corresponds to the down-counting time of the down-counter 10 is inputted to the microcomputer 9, and it is used as the signal for reading out a reference sine wave which is stored in a ROM 6. Therefore, even though the frequency of the three-phase AC power supply 1 is fluctuated transiently, the output frequency of the inverter 2 is not changed, and thereby, the output voltages of the three-phase AC power supply 1 and the inverter 2 can be switched to each other stably.

Title: Water purifyer
Inventor: ANDO SHIGERU
IPC: B01J20/20
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To increase the thermal efficiency of a water purifyer which uses a heating and regenerating system of an activated carbon by operating a heating means to directly heat the activated carbon during the device is not used. SOLUTION: City water is made to flow through a water passage 110 into a cartridge 101, where the city water flowing in is adsorbed and filtered by an activated carbon 102 and discharged through a porous cylinder 105 and an outlet passage 111. During the device is not used, high frequency electric power is applied from an induction heating and controlling means 150 to an induction heating means 120 to induce, heat and regenerate the activated carbon 102. By this heating method, the period of heating and regenerating the purifying device is reduced to 10 to 30 min. Thereby, problems of a conventional heater- type heating method that the contact rate between the cartridge 101 and the activated carbon 102 is low and that heat is hardly transferred to the activated carbon fiber can be avoided.  Since water is not used as a transfer medium of heat, problems of a conventional technique that water remaining in the cartridge disappears with heating and that thermal conductivity to the activated carbon 102 decreases can be avoided.

IPC: G06F3/14
Filed: 1993-06-15
Abstract: PURPOSE:To prevent a picture from being redisplayed when the hard copy is outputted with an optional output range and an optional enlargement rate, picture by picture.

When a system is generated, source data for picture display are converted into object data for picture display and registered, and the output range and enlargement rate of the hard copy set in the source data for picture display are registered. When a picture is displayed on a display device 35 at an operator's request, the registered object data for picture display and the output range and enlargement rate of the hard copy are stored in the memory 34-1 for picture display and picture display data are converted by using the output range and enlargement rate of the hard copy and outputted from the memory 34-1 for picture display to the memory 22 for hard copy output.

Title: Drum type washing machine
Inventor: NAKAMURA HARUHIKO
IPC: D06F21/04
Filed: 1977-11-28
Abstract: PURPOSE: To improve the efficiency of washing, by mounting an agitating body for forming washing water current into a rotary drum, and by turning the agitating body by using transmitting the revolution of the rotary drum.  
     CONSTITUTION: Wash is charged into a rotary drum 8 with a cleanser, and an opening and closing door 7 is closed. After feeding water, a motor 13 is conducted and the rotary drum 8 is turned. When an agitating blade 19 begins to sink under water in response to the revolution of the rotary drum 8, a driving gear 21 engages with an end surface gear 23 and turns on its axis while revolving, thus turn driving the agitating blade 19. That is, the agitating blade 19 creates eddy water current under water, and stirs wash. When the agitating blade 19 begins to emerge from water, however, the driving gear 21 is disconnected from the end surface gear 23, thus stopping the revolution of the agitating blade 19. Wash is atirred by both the agitation of the dipping-up and letting fall of a baffle 15 and the eddy water current of the agitating blade 19, thus improving the effects of washing.

Title: Writing pressure control pen
Inventor: NISHIDA KAZUO
IPC: G06F3/041
Filed: 1983-08-04
Abstract: PURPOSE:To obtain a pen which can control the writing pressure so as to avoid the injury of a coordinate input device by contriving such a mechanism where a pen point draws back when it receives the writing pressure higher than a prescribed level. CONSTITUTION:In an input period a spherical part 15 at the rear part of a pen point 12 is set at a space A and supported by springs 13 and 14. At the same time, the point 12 is protruded over a housing 11. When the writing pressure is higher than a prescribed level, it is impossible for springs 13 and 14 to hold the point 12. Thus the part 15 is moved up to a space B, and the point 12 is drawn into the housing 11. The minimum force to shift the part 15 to the space B from the space A is decided by the strongth of springs 13 and 14. A writer knows the excessive writing pressure from the shift of the part 15 and controls his/her writing pressure. If a push-out rod 16 is pushed under such conditions, the part 15 moves back to the space A. Then the normal writing is possible.
