Patent JP-H06323563-A (JP)
Title: Air conditioner
Inventor: OISHI KENICHI
IPC: B01F23/10
Filed: 1993-05-18
Abstract: PURPOSE:To air-condition a room so that the temperature distribution inside the room becomes uniform, by installing an air agitating device at a position in an air passage way after air passes through a heat exchanger and before air is distributed. CONSTITUTION:Air sent by a fan 2 passes through a heat exchanger 3, is agitated by a rotary disc 5a rotating on a rotary axle 5b, distributed by a distributor 6 and blown out from air outlets 7a and 7b. Although air turns to high- temperature air and low temperature air after passing through the heat exchanger 3 as the upper part of the heat exchanger 3 is higher in temperature than the lower part, the air is agitated by the rotary disc 5a and its temperature becomes uniform. The rotary disc 5a is turned on the rotary axle 5b by air flow. As air streams 4a having uniform temperatures are blown out from the air outlets 7a and 7b, air having the same temperature is blown out from the air outlets 7a and 7b. Therefore, the temperature distribution in a room becomes uniform and no uncomfortable place appears in the room, resulting in an economical air-conditioning without requiring capacities more than necessary for an air conditioner.

Title: Composition for judging inking amount of color ink for pressure-sensitive recording paper
Inventor: SAEKI YOSHISATO
IPC: B41M5/155
Filed: 1988-05-12
Abstract: PURPOSE:To enable the rapid and simple judgement of the inking amount of a color ink for pressure-sensitive recording paper, by using a color ink inking amount judging composition containing a dye or dye precursor changing a hue or absorptivity according to the degree of a pH value and a desensitizer. CONSTITUTION:The combination of a color ink with a desensitizer is the combination of a weak acid and a weak base. According to the quantity ratio, a capability of giving or taking off a proton is continuously varied. Therefore, by applying a composition containing a dye or dye precursor changing a hue or absorptivity according to the degree of a pH value to a sheet coated with the color ink, the absorptivity and hue is changed according to the amount of the loadings. This change is directly visually observed, measured by an optical densiometer, or compared with a hue comparison chart, whereby the inking amount of the color ink can be measured.

Title: Reflow device
Inventor: OTAKA HIROYUKI
IPC: B23K1/008
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To correct the warp of a softened printed wiring board by spraying compressed air to the warped part of the printed wiring board in a softened state. SOLUTION: An air spray exit for warp correction 6 is arranged below a cooling zone. Air blow is jetted from the air spray port 6 and it is sprayed to a printed wiring board transported by a transportation chain 2. The pressure of air blow is suitably adjusted by a blower 7. Thus, force operated upward operates on the printed wiring board and warp can be corrected. In the reflow device 1, air blow is strongly sprayed to the printed wiring board which passes through a heating zone 4 and is softened from below. Thus, warp bent by gravity can be corrected to an upper direction. When the warp of the printed wring board can be corrected, circuit, parts can securely be soldered by reversing the printed wiring board in the case of a double face substrate.

Abstract: PURPOSE:To enable the title semiconductor device to be made thinner by a method wherein the non-circuit formation surface of a semiconductor element and the rear surface of a tab are constituted to be flush with the surface of the title semiconductor device. CONSTITUTION:A bonding agent 2 is applied to the surface of a tab 3 so that a semiconductor element 1 may be bonded onto the tab 3 making the circuit formation surface on the element 1 oppose to the tab 3.

Abstract: PURPOSE:To prevent the speed of a vehicle from falling under constant-speed drive control, by detecting the quantity of the fall in the vehicle speed below a set level on an upward slope or the like and by increasing the quantity of supplied fuel to an engine when the quantity of the fall in the vehicle speed has exceeded a prescribed value. CONSTITUTION:In the driving of a vehicle, a vehicle speed signal generator 2 produces a  DC voltage corresponding to the speed of the vehicle and the voltage is applied to a constant-speed drive instruction unit 10 and a vehicle speed comparator 14. When a set switch 18 is turned off, a signal corresponding to the speed of the vehicle at the moment is stored in a memory circuit 28 by the constant-speed drive instruction unit 10 so  that the signal functions as a set level for the speed of the vehicle under constant- speed drive control. The difference between the set level and the actual speed of the vehicle is determined by the comparator 14 to regulate a throttle valve control unit 22 and a supplied fuel quantity control unit 40 to adjust the vehicle speed to the set level. When the vehicle speed has become lower than the set level and the duty ratio has become higher than a prescribed value, the control unit 40 performs the quantity increase compensation of a fuel injection signal 100 and an air by-pass valve control signal 102 to raise the vehicle speed.
