Title: Method for interconnecting closed foam
Inventor: UEDA MASAYOSHI
IPC: B29C67/20
Filed: 1988-03-26
Abstract: PURPOSE:To surely prevent crushing cracks from developing by a method wherein a foam-molded foam is worked with a pair of crushing rollers, on the peripheral wall of each of which projecting parts are provided. CONSTITUTION:Four pairs of rollers 21, on the peripheral wall 21a of each of a vertical pair of which a plurality of rows of annular projecting parts 23 are formed at certain axial intervals, are arranged so that each nip between the pair of which becomes gradually narrower along the moving direction A of a reaction pad 22. After the foam molding of the reaction pad 22 (hereinafter referred to as the pad), the pad 22 is passed between the pair of the rollers, each one of which has four sets of the projecting parts. As a result, the pad 22 is compressed by the rollers 21 and the projecting parts 23, resulting in interconnecting the gas within the pad to outside by escaping through gaps, each of which is produced by the peripheral wall 21a of the roller 21, the side wall of the projecting part and the pad 22, without the shifting of the gas within the pad through the interior of the pad 22. Accordingly, no rise of internal pressure by gas occurs at crushing and gas satisfactorily interconnects to outside, thus developing no crack.

Title: Car washing device and brush
Inventor: FUKUYA BUNKICHI
IPC: B60S3/06
Filed: 1990-03-22
Abstract: PURPOSE:To secure a sufficient car washing effect by installing a washing brush which comes into contact with a car in the wash and performs almost rectilinear motion. CONSTITUTION:Two motors 20 and 37 are operated by a controller and car washing is started. At a slide brush 3, with the motor 37 rotated, a shaft 36 at the upper side and a gear 32 are rotated via a chain 39, whereby a brush body 30 also comes to be rotated in consequence. In this case, in a portion between two shafts at both upper and lower sides, as the brush body 30 performs its rectilinear motion in the vertical direction, a tip part of a brush fiber 35, actually serving as washing off smudges, also comes to wash a car surface as doing the rectilinear motion. In brief, during this rectilinear motion, a piece-by-piece fiber of this brush fiber 35 washes the work surface in succession. In addition, there are provided two brushes 3 which rotate contrariwise to each other so that the smudges will in no case be left even on a step part or the like. Moreover, simultaneously, the washing is done also by a horizontal rotary brush 2 driven by the motor 20.

Filed: 1989-03-25
Abstract: PURPOSE:To permit defrosting while continuing space heating by a method wherein a route, bypassing an expansion valve provided in a refrigerant route from a condenser to an evaporator, is provided with an opening and closing valve. CONSTITUTION:A refrigerant flow system B, passing from a condenser 2 through an expansion valve 5 and arriving at an absorber through the other side of heat exchangers 10, 11 connected alternately through four-way valves 12, 13, is provided with a bypass route 6, bypassing the expansion valve 5, while said bypass route 6 is provided with an opening and closing valve 7. When an atmospheric temperature is reduced under the heating condition of a room, frost is accumulated on an outdoor heat exchanger 10 and the heat exchanging efficiency of the same is reduced. When the opening and closing valve 7 is opened at a proper time in order to prevent the deterioration of the heat exchanging efficiency, refrigerant vapor, generated in a regenerator 8, passes through a refrigerant route 4 through the condenser 2 under the condition of two-phase flow of gas and liquid and arrives at the outdoor heat exchanger 10 through the bypass route 6. Then, the heat of the refrigerant is dissipated in the outdoor heat exchanger 10 and the refrigerant is condensed while the accumulated frost may be molten and removed by the dissipation of the heat.

Abstract: PROBLEM TO BE SOLVED: To raise the accuracy of rotational position by suppressing the rotation ripple caused by the change from the state of current application to a motor by PWM(pulse width modulation) to current non-application state. SOLUTION: When a torque motor 10 cannot guarantee accuracy, with the absolute value of the duty ratio of the PWM signal from a PWM signal generator 30 exceeding the accuracy limit value and becoming a small range, at the time of change from current application state to current non-application state, in a bridge system of motor driving circuit which has two pairs of transistors Tr1 and Tr2 for driving, the two transistors Tr1 and Tr2 for drive are turned on or turned off, so that the counter electromotive voltage returns to the torque motor 10. What is more, the transistors Tr3 and Tr4 for drive at this time are turned off. Hereby, the counter electromotive voltage is generated also at current non-application of the torque motor 10, and braking action is produced, and the rotation ripples are suppressed.

Abstract: PURPOSE:To make production of the titled meter easy by surrounding hermetically the second electrode with a cover on a main body part, and applying a proper DC voltage between the first and the second electrodes to control the atmosphere of the second electrode so that it has a reference oxygen concentration. CONSTITUTION:An electrode 3 is covered up tight on the other face 1b of a main body part 1 by a cover 16. If a voltage switching circuit 18 is set to the first applica tion state by a control signal 22b when an oxygen sensor 14 is set in a gas 13 to be measured, oxygen molecules existing in a space 5 are ionized and are attracted to an electrode 2 and are discharged out of the main body part 1, and a current Ie between electrodes 2 and 3 becomes zero when the oxygen concentration in the space 5 is zero. When the circuit 18 is switched to the second application stage by the signal 22b oxygen ions are flowed reverse, and the current Ie is flowed from the electrode 3 to the electrode 2. When an electricity quantity signal 21a reaches a prescribed value, a control part 22 switches the circuit 18 to the third application state, and the current Ie is zero. An inter-electrode electromotive force due to the difference of oxygen concentration is generated between electrodes 2 and 3, and the quantity of electricity is detected by a detector 26, and the oxygen concentration is operated by a means 24.

Abstract: PURPOSE:To omit the processing including the waiting action of a software as well as the fast working of a peripheral device, etc., by thinning the clock signals inputted to an electronic circuit in order to make the electronic circuit perform a waiting action. CONSTITUTION:The wait request signals 106 outputted from the peripheral devices 103 - 105 are inputted to an LSI control circuit 101. If an LSI 102 owns a wait request input terminal but does not accept a wait request according to a mode, the signal 106 is inputted also to the LSI 102. A clock signal 107 to be originally inputted to the LSI 102 is inputted to the circuit 101 and outputs a clock signal 108 of an LSI after thinning the signals 107 via the signal 106. Thus a waiting action is attained with the simple processing including no fast working of the peripheral device nor application of software.
