Title: Piezoelectric pump
Inventor: HOSHI TAKAO
IPC: F04B43/04
Filed: 1990-09-11
Abstract: PURPOSE:To allow the smooth force feed without being affected by a solid foreign material contained in a fluid by providing piezoelectric elements on the respective valves provided on two flow ports mutually communicated through a pump chamber and on a diaphragm, respectively, and controlling the electrification of each piezoelectric element in a determined order. CONSTITUTION:At the time of operating a pump, a control circuit 20 first outputs driving voltages V1, V2 and then a driving voltage V3, and this alternate output is repeated. When the driving voltages V1, V2 are outputted, a piezoelectric element 6 is curved and deformed, a diaphragm 5 is swollen on the back surface side of a case 1, and a piezoelectric element 9 is curved and deformed in the direction of the diaphragm 5 to forcedly open an intake valve 8. Thus, a fluid is introduced into a pump chamber P from an intake hole 2 through the intake valve 8. Then, when the driving voltage V3 is outputted, a piezoelectric element 12 is curved and deformed in the outward direction of a discharge hole 3, and a discharge valve 11 is forcedly opened. At this time, the current sending to the piezoelectric elements 6, 9 is interrupted, the diaphragm 5 is displaced on the front surface side of the case 1 as shown in an actual line, and the intake valve 8 is closed. Thus, the fluid in the pump chamber P is discharged out from the discharge hole 3 through the discharge valve 11.

Filed: 1988-09-26
Abstract: PURPOSE:To enable measuring a meandering value accurately and to enable correcting the meandering accurately by opening a side guide during plate rolling and detecting the meandering of the plate at that time. CONSTITUTION:The plate 1 to be rolled on each rolling stand 2 is restricted by the side guide. 3. After starting the rolling, at the starting time for coiling the front end of the plate on a down coiler, the guide 3 is moved from an off state position A shown by a full line to an on state position B shown by a dotted line.

Abstract: PURPOSE:To imprint data without providing a data imprinting device by positioning the potential detection part of a photosensitive drum at an image exposure position, and composing an eraser of a writable light emitting element array. CONSTITUTION:The measurement of the surface potential of a photosensitive drum 1 and the imprinting of data differ in operation timing, so a surface potential measuring device is used even for the data imprinting operation in common. A data imprinting device 17 consists of an interimage eraser unit 200, optical path shutter 210, surface potential sensor 211, eraser 220 for a surface potential detection part, etc. Then, LEDs 200a-200e of the interimage eraser unit 200 are turned off in data imprinting mode and the data imprinted part of the photosensitive drum 1 is not erased. The seven LEDs 220a-220g of said eraser 220 constitute a column of a dot matrix of five rows and seven columns of dots. There is no probelm in terms of space, so data is imprinted at low cost even by a small-sized copying machine.

Title: Antenna
Inventor: KOIZUMI TAKAYUKI
IPC: H01Q15/20
Filed: 1986-10-09
Abstract: PURPOSE:To improve the radio wave characteristic without the generation of a standing wave due to vibration within a face of screen by adopting the shape of outer circumference of the screen face forming a reflector as a shape changed in a way of white noise in response to the location change in the circumferential direction. CONSTITUTION:The outer circumference edge of the thin screen 4 is formed to be subjected to change in white noise in response to the location change in the circumferential direction. Supposing that the frequency of radio wave for communication is nearly 10GHz, the wavelength of the radio wave is nearly 3cm, then the error of the parabolic face due to the mechanical vibration is >=10% with respect to the wavelength of the radio wave and it cannot be ignored. Since no parallel face exists in the screen face 4 on the other hand, no standing wave is generated and no increase in the delivered vibration takes place. Thus, even if the titled antenna is used while being coupled with an artificial satellite in universe space, an excellent radio wave characteristic is obtained.

Title: Preserving cabinet for vegetable
Inventor: MARUO KATSUHIKO
IPC: A01F25/00
Filed: 1988-09-26
Abstract: PURPOSE:To smooth opening and closing of a door in a pullout type preserving cabinet for vegetables having a construction in which an impermeable flexible sheet is vertically moved interlocking with the opening and closing of the door and the vegetables are covered by providing a string and pressing pawl for performing specific action. CONSTITUTION:A door 1 of a pullout type preserving cabinet for vegetables is pulled out to lift an impermeable flexible sheet 2 by action of a string 14. Vegetables 5 are then housed in a vegetable preserving container 3 and the door 1 is closed so that the sheet 2 may tend to fall by gravity. The sheet, however, remains pulled up with engagement of a pressing pawl 15 with the string 14. When the door 1 is completely closed, the upper end of the pressing pawl 15 is pressed with a pushing rod 16 to release the engagement thereof with the string 14 and the sheet 2 falls by gravity to cover the vegetables 5. Thereby, since the volume in the preserving space is reduced in preserving the vegetables, air composition in the space attains that suitable for preserving the vegetables in a short time. The vegetables can be preserved in a fresh state for a long period without catching the sheet 2 with the vegetable preserving container 3 in opening or closing the door.
