IPC: G01M17/007
Filed: 1988-09-30
Abstract: PURPOSE:To miniaturize an operation box by mounting a filter circuit for the signal of push button, a holding circuit and a reset circuit. CONSTITUTION:When each of the push button switch 3 of A-D is pushed down after the completion of respective working course, a signal is held by a flip-flop circuit FF 5 through an input filter circuit 4. Next, when the push button switch of the same working course is again pushed down, the Q-output of the FF 5 becomes 0 from 1 and the Q-output thereof becomes 1 from 0 and the signal to a display device main body 9 is also reset. When a completion push button is pushed down in the input state of each switch 3, the signal is held by the FF 5 and transmitted to the main body 9 and the output of each FF 5 is reset. As mentioned about, by using the holding circuits of the push button switch signals of the completion of working courses by electronic circuits and the circuit for resetting the same all at once in common, an operation box can be miniaturized.

Title: Water receiving construction for air conditioner
Inventor: OSADA TAKESHI
IPC: F24F13/22
Filed: 1985-11-01
Abstract: PURPOSE:To prevent the splashing of water due to swallowing up a water condensate or the leakage of water due to a raised water level developed by pressure difference by providing a water receiving pan with a water outlet opening and a gate board with a water condensate discharge hole on the lower side of a heat exchanger. CONSTITUTION:The lower end of a heat exchanger 1 is provided with a gate board 5 which has a water condensate discharge hole 4, and part of the water condensate flows down to a water receiving pan 3 from the water condensate discharge hole 4, and on the other hand, the water condensate which has flowed down to the rear of the heat exchanger 1 flows on the inclinded section of the gate board 5 and downward from the rear and 5a of the gate board and it is discharged to outside from a drain opening 3a provided in the water receiving pan 3. Since the gate board 5 prevents the short-passing of the air flow underside of the heat exchanger 1, and at the same time the water condensate drain hole 4 works as both a discharge hole and a pressure equalizing hole, the upstream side of the heat exchanger 1 and the inside of the water receiving pan 3 can be at the same pressure. And since the rear end 5a of the gate board 5 has an obtuse angle, there is little of swallowing up the air.

Title: Frequency and stroke depending type damper
Inventor: SHIMIZU KEIICHI
IPC: F16F9/48
Filed: 1985-10-30
Abstract: PURPOSE:To improve comfortability to ride and drivability, by providing a stable stroke-dependent damping force characteristic when a vibration frequency operating to a damper is low, while increasing a damping force without stroke dependency when the vibration frequency is high. CONSTITUTION:A gas chamber S4 is defined by a piston 12 outside or inside a damper. The piston 12 is biased to the gas chamber S4 by a spring 13. The piston 12 and the spring 13 have a resonance frequency. The gas chamber S4 is compressed and expanded according to a change in pressure upon expansion and compression of the damper. An amount of hydraulic oil flowing between upper and lower oil chambers S1 and S2 in a tube 2 is decreased by the change in volume of the gas chamber S4, thus obtaining a stroke-dependent damping force. On the other hand, when a vibration frequency from an unsprung part is higher than the resonance frequency, the piston 12 eliminates the stroke- dependent characteristic and generates a high damping force.

Title: Cell decomposing circuit
Inventor: YAMAMOTO TORU
IPC: H04L47/43
Filed: 1991-09-25
Abstract: PURPOSE:To miniaturize a device and to improve the use efficiency by providing an input buffer logically divided by individual transmission device information, a secondary buffer, and a work memory and independently decomposing a multiplexed input cell to reproduce it into an arbitrary packet length. CONSTITUTION:The cell inputted from an input cell data line 10 is stored in an input buffer 110 in the position corresponding to transmission device information. If error is reported at this time, the cell is abandoned. When an error flag is not set, a work memory control part 130 writes the number of transmission device information in a FIFO type work memory 140 and writes final data in the detection order. When the output end of a secondary buffer 150 is confirmed thereafter, stored cells are read out from the buffer 110 from the start and are transferred to the buffer 160 and a cell omission detecting circuit 150. When being informed of cell omission, the buffer 160 abandons a packet of arbitrary length being in source of assembling. Thus, the device is miniaturized and the use efficiency is improved.

IPC: C09D123/16
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic tire for preventing a decrease in appearance property with excellent ozone-proofness. SOLUTION: The pneumatic tire is obtained by vulcanizing unvulcanized rubber composition containing ethylene-propylene-diene terpolymer rubber(EPDM) as a main component and hence forming ozone-proof thin film layer of the composition.

Specifically, a surface of an unvulcanized tire is coated with the cement to form a thin film, then the unvulcanized tire is vulcanized to obtain the tire having the ozone-proof thin film layer. The diene component of the EPDM contains ethylidene norbornene.
