Title: Drum type washing machine
Inventor: HONDA KUNIOKI
IPC: D06F37/26
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To reduce the cost of a bearing attached to an outer tank and a drum. SOLUTION: A backwardly open U-shaped notch 13b is formed in a mounting margin at the end of the arm 13a of a bearing, and the threaded part of a bolt 31 is threaded into its groove 13c with a nut 33 fitted around the inner periphery of the bolt 31 via a washer 34. When the bolt 31 and the nut 33 are tightened together, the washer 34 presses the notch 135, securing the bearing to an outer tank. Since the bearing has no through hole, it can be molded also by rapping in the one-dimensional direction. Therefore, the cost of molds is low and molding processes become simpler.

Title: Semiconductor device
Inventor: TAKESHITA YUICHI
IPC: H03K17/16
Filed: 1988-10-03
Abstract: PURPOSE:To prevent the malfunction of semiconductor device by dividing output buffers to blocks and shifting the switching time of output for each block to suppress the quick rise of the ground potential. CONSTITUTION:For example, 16 output buffers are divided to four output buffer blocks B1 to B4. The circuit constitution of each buffer consists of a CMOS transistor TR Trc. Capacitors C1 and C2 and resistance elements R1 and R2 are built on sides of input terminals I1 and I2 of the output buffer, and their time constant is shifted for each of output buffer blocks B1 to B4. That is, the input is successively shifted by a certain time T to divide output buffers into four, and the voltage rise of the GND level is reduced to 1/4 conventional that per one switching. Thus, the voltage rise is prevented from exceeding a logical threshold V1 of the semiconductor device.

Abstract: PROBLEM TO BE SOLVED: To provide a magnetic recording medium provided with a high degree of security function by having a non-writable fixed magnetic pattern region and non-fixed recording region on one sheet of magnetic card. SOLUTION: A supporting base body 2 is coated with a magnetic coating material 4 at a thickness of about 100μm by a coating head device 3 in a phase 1. The magnetic particles 4A suspend and exist uniformly in a random state in a vehicle 4B in this state. A magnetization effect is applied in the vertical direction of the base body by a magnetizing device 5 and the state in which the coarse/dense states of the magnetic particles are generated in the coating film is attained by the effect of the attraction/release in a phase 2. The axes of easy magnetization of the magnetic particles directed toward the vertical direction are oriented toward the coating applying and traveling direction by a magnetic orientation device 6 in a phase 3. The solvent in the magnetic coating material is evaporated by a drying furnace 7 and the thickness is reduced to about 15μm, by which the coarse/dense states of the magnetic particles are fixed into the coating film in a phase 4.

Abstract: PROBLEM TO BE SOLVED: To exploit a performance of a hammer part to a limit without decreasing a life of the hammer part by changing a specified value in accordance with an average number of print dots of a latest one stroke which is a drive result of a printing element and controlling a print density. SOLUTION: Print data is sent from a printing control means 1 to a printing buffer 2 and a hammer circuit 3 drives a hammer 4 in accordance with the print data in the printing buffer 2, whereby printing is carried out. Simultaneously when the print data is transferred to the printing buffer 2, a counter 5 counts the number of dots of the print data. When an average number of dots per stroke which is a latest drive result of the hammer exceeds a specified value 1, the specified value is selected until the number of dots per stroke becomes the specified value 1 or smaller. A counted value of the counter 5 is compared by a comparator 9 with the specified value selected by a specified value-selecting circuit 8. When the counted value exceeds the specified value, discriminated hitting is carried out by a discriminated hitting limit circuit 10.

Filed: 1983-12-23
Abstract: PURPOSE:To reduce a drop in the photooutput under high peripheral temperature while improving starting under low peripheral temperature by providing amalgam mercury in a crooked inner tube not adjacent to an electrode while sealing a very small amount of mercury vapor into an outer tube. CONSTITUTION:For instance, in addition to setting up amalgam mercury at the base of the columnar part of a central U-shaped inner tube 3, almost vapory mercury is sealed inside the tube. A very small amount of mecury initially sealed in and the mercury vaporized from amalgam mercury do not get back to amalgam so that a very small amount of mercury is successively filled up inside the tube thus removing instability characteristic to the initial stage of lighting. Further, even when a temperature around a lamp is high, a drop in the photooutput at the time of a high surrounding temperature can be checked, if the total amount of mercury grains at the initial sealing-in time together with the mercury vaporizing from the amalgam mercury is made not to exceed 10mTorr.
