Title: Clean room
Inventor: SAITO MASANOBU
IPC: F24F3/16
Filed: 1985-05-28
Abstract: PURPOSE:To prevent contamination in a highly clean region due to approach of workers' bodies effectively, by providing a means, which changes the ratios of exhaust air quantities among a plurality of exhaust ports, and minimizing the quantity of flowing clean gas in the highly clean region. CONSTITUTION:Based on data from a sensor 18, the ratios of exhaust air quantities of exhaust ports (QE/QH) and [(QH-QE)/QH] with respect to diffused air into a clean region A are kept at preset steady ratios (QE/QH=K1) and [(QH-QE)/QH=K2], under the state workers and the like do not approach the highly clean region A. When the workers approach the region, the ratio of the exhaust air quantity at the second exhaust port 10 [(QH-QE)/QH] with respect to the diffused air into the clean region A is made to be the value (K2+DELTAK2), which is larger than the steady ratio K2 by a preset width DELTAK2. At the same time, the ratio of the exhaust air quantity at the first exhaust port 9 (QE/QH) is made to be a value (K1-DELTAK1), which is smaller than the steady ratio K1 by a preset width DELTAK1. In order to obtain these values, a damper 17 is automatically operated by a control device 19.

Title: Key switch
Inventor: WATANABE MAKOTO
IPC: H01H13/702
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To provide a key switch, in which the number of part items to be used for hinge member thereof is reduced so as to lower the manufacturing cost and of which thick pushing member can be formed into a desirable shape. SOLUTION: A central position of a second hinge member 8 is formed with a push-down part, which is placed on a top surface of a rubber spring 35 and which pushes down the rubber spring 35 when a key switch 1 is pushed down. The push-down part pushes the rubber spring 35 so as to buckle it for switching operation. The second hinge member 8 is formed by extruding the synthetic resin, but since a surface of the push-down part opposite to the push-down surface is formed with a recessed part 18a, the number of part items to be used for the second hinge member 8 is reduced, and generation of the shrink of the synthetic resin in the push-down part at the time of extrusion is prevented. A pushing surface of the push-down part can be formed into a desirable shape.

Title: Composite cooking range
Inventor: HIRAI KIYOSUMI
IPC: F24C1/02
Filed: 1982-07-02
Abstract: PURPOSE:To improve the cooling effect by a method wherein a right and left partitioning plate for dividing an exhaust port forwardly and rearwardly is provided around a combustion chamber and a front and rear partitioning plate is provided on the upper surface of a heating chamber so as to form the letter T with the right and left partitioning plate so that air from a cooling fan is discharged after it passes by the side surface of the heating chamber. CONSTITUTION:Air sucked by the cooling fan 5 cools a magnetron 4 and flows over the upper surface of the heating chamber 3. Then a part of the air is discharged from an exhaust port 1b and a part of the air becomes combustion air by being sucked from a sucking port of a burner 7. The combustion air enters the heating chamber 3 through the combustion chamber 15, a circulating fan 16 and a duct, returns to the combustion chamber 15 through punched holes 19a of the partitioning plate 9 and is discharged from the exhaust port 1b through an outlet port 20. Further, a part of the cooling air 5 flows upward from the lower surface of the heating chamber 3 toward the opposite side surface 11 along the partitioning plate 9 and is discharged from the exhaust port. An exhaust port 1c is for discharging cooling air from the circulating fan 16. Thus it is made possible to prevent interference of the air flow and to improve the cooling effect of the cooking range.

Title: High speed dda converting system
Inventor: SAKAI MASATOSHI
IPC: G06T11/20
Filed: 1988-05-12
Abstract: PURPOSE:To display a straight line, etc., at a high speed by completing addition and subtraction for the computation of one address in one time of operation in high speed DDA conversion to generate an address to correspond to the straight line, which goes from a starting point to a termination. CONSTITUTION:The starting point is defined as (0, 0) and the termination is defined as (mx, my). Then, as pre-processing at first, the smaller number of the mx and my is substituted for a d1 and the difference of mxm1 is substituted for a d2. An initial value (mx/2-my) is substituted for a second value mr. Thirdly, the positive and negative of the mr is decided. When the mr is negative, the d2 is subtracted to the mr and when the mr is positive or 0, the d2 is subtracted to the mr. While these three steps are repeated, 1 is added to the address in direction (an x-direction or a y-direction) of the larger number of the mx and my. Then, when the mr is positive, 1 is added in the direction of the smaller number. Then, the address is generated.

Title: Electrostatic recording method
Inventor: INOUE MOTOICHIROU
IPC: G03G15/05
Filed: 1980-08-25
Abstract: PURPOSE:To prevent formation of an indistinct picture without providing a large capacity memory, by executing a developing treatment of an electrostatic latent image whose development is not treated yet before the potential of a picture carrier drops, and also returning the surface potential of a dropped picture carrier. CONSTITUTION:A beltlike picture carrier 1 moves intermittently, is treated by an electric charger, an arraylike exposure device 6, a developing device 7, etc., and stops when an exposure signal from the device 6 is discontinued. When this discontinued period exceeds a prescribed period before the potential of the carrier 1 drops, the carrier 1 moves by a prescribed extent by a motor 4, and a latent image, whose development is not treated yet, of an area J of the carrier 1 is brought to a developing treatment clearly. Subsequently, when a signal comes to be supplied to the device 6, the carrier 1 is shifted in reverse, and also an ionic current and an optical irradiation by corona discharge of an auxiliary discharger 19 and an auxiliary charger 18 are detected. As a result, the potential of the dropped area I, etc. of the carrier 1 is released without exerting influence on the picture. Accordingly, an indistinct part due to drop of the potential is not generated in the picture formed on the whole surface of transcription paper 13, without using a large capacity memory.

Abstract: PURPOSE:To improve machining performance, by providing a machining position detector so as to perform a servo control of good follow-up property, in the case of a control device having a discriminator circuit, adjusting a machining gap corresponding to every pulse or plural pulses, position control servo system and a main spindle feed gain controller. CONSTITUTION:A discriminator circuit 18 outputs a servo signal, which adjusts a machining gap corresponding to every pulse or plural pulses, and a control device, supplying an up-signal and a down-signal obtained from the circuit 18 to AND circuits 22, 24, obtains an AND output from an output side to be integrated for a required time in an updown counter 26. The device holds this counted value in a register 28 to be output to a main spindle feed gain controller 52. And the servo signal, which controls a difference between the present output value of the register 28 and its just preceding output value so as to obtain a preset value, is output to a sample value control system and converted into a main spindle position command value. Here a logical operation circuit 24, reading an output from an error counter 36, that is, a difference Zepsilon between a zero degree hold output Zc and a position detection signal Zf and calculating the next zero degree hold output in a fine time, enables a high accurate gap control to be performed.
