Title: Dishwasher
Inventor: MATSUNO TOMOHIKO
IPC: A47L15/42
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To prevent water leaking to the side of a drain pump chamber from the side of a washing pump chamber. SOLUTION: Seal consisting of labyrinth coupling using surface unevenness is applied between a washing impeller 41 and bulkhead 40 and between a draining impeller 42 and the bulkhead 40. This configuration generates a very large flow resistance of a flow path leading from the periphery of the washing impeller 41 to the periphery of the draining impeller 42 via a through hole 40e provided in the bulkhead 40. Accordingly water leaking from the side with a washing pump chamber to the side with a drain pump chamber via the through hole 40e can be nullified substantially even when the washing impeller 41 is in rotation.

Filed: 1982-09-03
Abstract: PURPOSE:To make it possible to perform the control of violation of the speed regulations without being noticed by the driver of a vehicle, by measuring the speed of the vehicle by emitting a microwave to the vehicle in the right angle direction with respect to said vehicle. CONSTITUTION:The microwave from an oscillator 7 is emitted to a vehicle 2 from an antenna 9 through a change-over device 8 and the reflected wave thereof is received by the antenna 9 to be supplied to a hybrid 10. In this hybrid 10, the reflected wave is divided into a sum signal and a difference signal but, at the output terminals TP1, TP2 thereof, the positions of the antenna 9 and the vehicle 2, that is, output according to the relative speed therebetween is obtained. When the vehicle 2 is present in a direction B, the output of the sum signal TP1 comes to a max. value and the output of the difference signal TP2 comes to a min. value. The sum signal is reduced in a direction A or a direction C and the difference signal is increased in said directions. In addition, when the vehicle 2 is present to the right side of the antenna 9, both of them mutually come to a same position while, when it is present to the left side thereof, an inverse phase is brought and the position of the vehicle can be detected as an angle signal and the speed of the vehicle 2 can be detected from the output of TP3. By performing measurement by emitting the microwave to a right angle direction, the control of violation of the speed requlations can be performed without being noticed by a driver.

Title: N-times speed cutting apparatus
Inventor: KOIZUMI TOSHIO
IPC: G11B7/0045
Filed: 1991-05-30
Abstract: PURPOSE:To sharply shorten the required time for a recording operation to a glass raw disk by means of a CD cutting machine by providing the following: a storage device which demodulates and reads out an EFM modulating signal at a speed of N times; and a turntable which turns the raw disk at N times the decided number of revolutions. CONSTITUTION:When the transfer rate of an EFM signal for a compact disk(CD) is increased to N times and the operating frequency of a CD encoder 4 and the number of revolutions of a CD cutting machine are increased to N times in the same manner, the time required for a cutting process can be shortened. Since it is difficult technically to increase the transfer rate of the EFM signal to N times, the transfer rate is set at an ordinary transfer rate up to the output of the CD encoder 4, the EFM signal is stored in a storage device and the EFM signal is read out, from the storage device, at a transfer rate corresponding to the CD cutting machine whose number of revolutions has been increased to N times. Thereby, the required time for a recording operation to a glass raw disk by means of the CD cutting machine can be shortened sharply.

Filed: 1987-06-19
Abstract: PURPOSE:To lessen the decrease in the quantity of electricity to be implanted and to maintain a high response characteristic without generating unequal displaying even if a display element is subjected to cold-heat temp. cycles by using carbon powder having specific shapes as the carbon powder to be used for a counter electrode material layer of a counter electrode. CONSTITUTION:The material layer 6 of the electrochromic display element is formed of a thin tungsten oxide film and an electrolyte 15 contg. a lithium salt and nonaq. solvent which dissolves said salt is used. The carbon powder which has the specific characteristic of <=5pH of the supernatant liquid obtd. after immersing the powder in 10wt. times pure water and boiling the water for 1.5min and has a proton supplying capacity is used as the carbon power to be used for the counter electrode material layer 10 of the counter electrode 8. The effect of improving the preserving stability of the element is lost if the pH value exceeds 5 and the decrease in the quantity of electricity to be implanted and the degradation of a counter electrode 9 in the initial period are easily generated if the pH value is lower than the limit. The quantity of the electricity to be initially implanted is thereby decreased and the stable high response speed is maintained. The unequal display is prevented even if the element is subjected to the cold heat temp. cycles.

CONSTITUTION:On the base material 2 of a substrate 1, a plurality of insulating members 8 are formed between pads 3. The thickness T of the insulating member 8 is at least twice as much as the thickness t of the pad 3. Creamy solder 5 is supplied to the specified outer part of a printed substrate 1 with the insulating members 8 and the pads 3 located as stated above. Then, a squeegee 7 is set on the printed substrate 1 so that its head abuts on the upper surfaces of the insulating member 8. Rubbing on the upper surfaces of the insulating members 8, the squeegee 7 moves in parallel with the surface of the base material 2. Because of the parallel squeezing of the squeegee 7, the creamy solder 5 is spread thin on the printed substrate 1. Nextly, terminals 4 of surface mounting components are placed on the pads 3 on which the creamy solder 5 is applied. By melting the creamed solder 5 by the reflow soldering method and then hardening it again, the terminals 4 are joined to the pads by solder.
