Title: Water wheel starting
Inventor: KAWAMOTO KAZUTOSHI
IPC: F03B15/04
Filed: 1978-05-04
Abstract: PURPOSE: To start the water wheel from the phase modifying operation quickly and smoothly by exhausting air from the runner chamber and opening the inlet valve after the pressure in casing is made less than that in the iron pipe on opening the guide vane.  
     CONSTITUTION: The pump water wheel is constructed such that the draft tube 3 is provided to the location just under the runner 2 connected to the main shaft 1, the casing 5 is installed on the side of runner 2 through the guide vane 4 and the iron pipe 7 is connected to the casing 5 through the inlet valve 6. When the pump water wheel is shifted from a phase modifying operation to a water wheel operation, air in the runner chamber is exhausted first, the guide vane is opened to make the pressure in the casing 5 less than that in the iron pipe 7 next, and the inlet valve 6 is opened last. By this, water flows in the casing from the iron pipe smoothly, the starting can be accomplished in a short time.

Abstract: PURPOSE:To prevent waste stencil base paper from being wound around a take-up roller by a method wherein stencil base paper is pressed into a containing part of a rotating part, said rotating part is rotated, and the stencil base paper in the containing part is compressed by a guide plate of a disposal part. CONSTITUTION:When a release claw 3 peels the end of stencil base paper S from the surface of a plate cylinder 1, the stencil base paper S is fed by a take-up roller 4 to be peeled from the plate cylinder 1, thereafter being contained once in a containing part 13 of a rotating part 8 in a compressed state by the take-up roller 4. Next, the rotating part 8 rotates in such a direction as an opening of the containing part 13 follows in the rotating direction. The base paper S is guided by a lower guide plate 20, stored in the containing part 13, and fed toward a waste plate box 17. The base paper S in the containing part 13 is pressed by an upper guide plate 19 with the rotation of the rotating part 8 to be further compressed against the lower guide plate 20. When the rotating part 8 is rotated through 180 deg. from the former position, the compressed base paper S is pressed by the upper guide plate 19 to be discharged from the containing part 13 and thrown into the waste plate box 17 from an outlet 18.

Title: Piezoelectric type water-level sensor
Inventor: USUDA NOBUHIKO
IPC: G01F23/22
Filed: 1988-03-07
Abstract: PURPOSE:To obtain a water-level sensor being small in size and excellent in precision in detection, by constructing a vibrator by sticking a piezoelectric porcelain plate on the upper surface of a metal plate and by sticking the lower surface of the metal plate on the bottom surface of a case made of resin. CONSTITUTION:A piezoelectric type water-level sensor 8 is constructed of a vibrator prepared by sticking a piezoelectric porcelain plate 1 on the upper surface of a metal plate 2 and by sticking the lower surface of the metal plate 2 on the bottom surface of a cylindrical case 3 made of resin and opened on one side. Since the value Q of this vibrator is low, a stable detection characteristic is obtained because of a small change of its impedance even when filth such as beef tallow sticks on the bottom surface part of the case 3, and also the sensor can be made small in size. Moreover, the excellent responsiveness of an impedance characteristic to a liquid 9 enables the quick detection of a change of the liquid in a sharp temperature difference, and thus the sensor can be used effectively for a tableware washer or a washing machine.

Title: Method of driving laminated piezoelectric element
Inventor: KAWANAMI HIROSHI
IPC: H01L41/083
Filed: 1988-03-07
Abstract: PURPOSE:To assure a greater power to generate a displacement of the title piezoelectric element and hence a greater amount of the displacement by utilizing the displacement of the element in a direction of contraction of the element by bipolar-driving the element over a minus potential side less than an anti-electric field and a plus potential side. CONSTITUTION:Piezoelectric material layers and electrode layers are alternately laminated and a voltage is applied across the electrode layers. Hereby, the piezoelectric material layers are contracted. Then, a voltage of positive and negative both polarities is applied across the electrode layers, one polarity voltage being opposite to application voltage upon initial polarization of the piezoelectric material layer and less than an anti-electric field, the other being same as the foregoing application voltage upon the initial polarization. Therefore, the laminated piezoelectric element is bipolar-driven over the minus potential side below the anti-electric field and the plus potential side. Accordingly, if a reference displacement is defined to be a contracted state of the element on the minus potential side, a contraction displacement on the minus potential side is added to an elongation displacement on the plus potential side, thereby assuring a greater displacement compared with monopolar driving where voltage is applied unidirectionally.

Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To avoid the fact that, when a semiconductor circuit is generated with an IC placement wiring system, the interval between gaps is narrowed according to design rule, resulting in increased inter-wiring capacity for larger wiring delay. SOLUTION: After initial wiring (42) is performed, inter-wiring distance of each wiring and parallel distance are calculated (43). By considering a wiring capacity condition description, wiring-impossible region for each wiring is set (44). With the impossible region, such wiring as violating design rule is re-wired (45), and wiring delay is calculated (46). When such limit condition as in wiring delay limit condition description is met, wiring process is complete. When it is not met, the wiring impossible region is expanded, and wiring and calculation of wiring delay are repeated. If the limit condition is not met by a specified frequency of repetition, such placement wiring description as for circuit of least wiring delay among the repetition is generated.

Filed: 1980-04-25
Abstract: PURPOSE: To enable to perform smooth parallel positioning work of the wafer by a method wherein a wafer chuck is elastically supported in a chuck support being enabled inclining motion by a spring member, and a lock mechanism is provided to constitute a wafer supporting part.  
     CONSTITUTION: When the chuck support 33 comes up, the support 33 moves to incline bending a plate spring as to make the surface of a wafer 20 to come in contact with respective leveling pads 30. Accordingly the wafer 20 is so regulated as the surface thereof is made to coincide with the standard face. When a pressure sensing element 36 detects that upward pressing force reached at the prescribed value, a detected signal therefrom is inputted to a control circuit 37, the circuit 37 supplies a current to electromagnets 52, and the electromagnets 52 absorb a lock plate 51.  As a result, the wafer chuck 38 is locked in that condition, and thereafter although  the wafer 20 is removed from the pads 30, the wafer 20 can be held in the condition as it is. After then by making the support 33 with the chuck 38 and the wafer  20 to come down in parallel, the position of the surface of the wafer 20 can be set  up precisely.
