Title: Radiant heat exchange type cooler for preventing dew condensation on cooling plate surface
Inventor: YAMADA JUN
IPC: F25B39/02
Filed: 1994-03-29
Abstract: PURPOSE:To prevent condensation on a surface of a cooling plate by providing a heat insulation plate so surrounding as to form a space between the cooling plate and an infrared transmission plate or film. CONSTITUTION:A radiant heat exchanging type cooler 10 has a cooling plate 12, an infrared transmission plate 14 and a heat insulation plate 18, and comprises a cooling tube 16 in which refrigerant such as water, fluorocarbon, etc., flows and which is provided adjacently on a back surface of the plate 12, wherein the plate 14 is formed, for example, of polyethylene, single crystalline germanium, silicon, etc. In this case, the plates 14 and 12 are surrounded by the plate 18 thereby to form a space 20. Dry gas having a dew point of 10 deg.C or lower is charged in the space 20. Further, the space 20 is evacuated substantially in vacuum thereby to set a surface temperature of the plate 14 substantially to the same as the ambient temperature. Thus, condensation on the surface is prevented, and a decrease in a cooling effect and generation of milder is prevented.

Title: Musical sound generating device
Inventor: IZUMISAWA GEN
IPC: G10H7/04
Filed: 1990-03-30
Abstract: PURPOSE:To downscale a circuit for interpolation by providing a waveform memory stored with musical sound waveform data and performing the interpolation by using waveform data stored in respective integer addresses when a read address specifies the part between a 2nd integer address and its last integer address. CONSTITUTION:The waveform memory 8 is connected to a sound source circuit 7. When musical sound waveform data is stored in the waveform memory 8, the data is stored in the range from the integer address indicated by a loop top to the integer address right before the integer address indicated by a loop end, the same musical sound waveform data as that stored in the integer address of the loop top is stored in the integer address of the loop end, and next musical waveform data is stored from the integer address following the integer address of the loop end. Further, when the musical sound waveform data is read repeatedly and interpolated. The data is interpolated without judging whether or not the address for the interpolation exceeds the loop end. Consequently, a hardware need to judge the loop end is eliminated and the circuit scale is reducible.

Abstract: PURPOSE:To prevent the going up of the lamp voltage or the leakage of gas in the tip portion of a lamp by locating the tip portion of a luminous tube on the upper side of the horizontal plane passing through the center of the luminous tube and on either side of and apart from the central cross section passing through the center of both electrode ends when the lamp is lighted in porizontal psition. CONSTITUTION:The tip portion 2 of a luminous tube 1 is provided on a portion 8 mm apart from the center of both electrode ends on one electrode side. In the luminous tube 1 a pair of electrodes 3 connected to outer lead wires 5 through metal foils 4 respectively is provided. The discharge arc 12 is curved upward by the buoyancy. and especially in the central portion between the ends of the electrodes 3 the are 12 is adjacent to the inner wall surface of the luminous tube 1 so that a locally heated high temperature area is produced. But ths tip portion 2 is located on one electrode side of the center of the ends of the electrodes 3, thus the tip portion is located outside of the local high temperature area. Thereby the tip portion can be avoided from the local high temperature area so that the going up of the lamp voltage due to the ejection of water vapor from the tip portion or the leakage of the gas in the tip portion due to the reaction of the sealed metal and the quartz of the luminous tube can be prevented.

Title: Exposure system of optical printer
Inventor: SHIMADA KAZUYUKI
IPC: G03G15/04
Filed: 1988-04-04
Abstract: PURPOSE:To prevent double exposures (ghost) caused by the uneven feed of a photosensitive body drum when the same data are exposed at the same place of the photosensitive body drum by decreasing or increasing the width of a strobe signal of each line sequentially compared to those of reverse lines with plural lines of light sources set against the feed direction of the photosensitive body drum. CONSTITUTION:The widths T1, T2 of strobe signals S1, S2 are in the relationship of T1>T2, and the strobe signals drive latch circuits 46-1, 46-2 with temporal difference. The number Sn of the strobe signals S1, S2 is provided in proportion to a group of N lines of elements arranged on an EL panel 20 in such a manner that the widths are set in such a relationship as T1>T2...TN or T1>T2>...>TN. For instance, if the widths T1, T2 of the strobe signals S1, S2 in the first and second lines represent the relationship of T1>T2, the second line L2 is written inside the first line L1. Therefore, it is possible to prevent double exposure, if the feed of the photosensitive body drum were uneven.

Abstract: PURPOSE:To enable ash conveyance excellent in a conveying capacity by setting up more than one set, consisting of a valve and a fluid intake free being free of opening or closing at the downstream side of this valve in a fluid conveying pipe lying between a hopper and a bag filter being inhaled by a vacuum blower. CONSTITUTION:When all valves 11 are opened and a degree of vacuum in a vacuum gauge 9 is less than the setting value VC1, a controller 10' opens as ash intake 3, feeding ash from an ash hopper 2 to a fluid conveying pipe 4, and it collects at the ash in a bag filter 5.

When it comes less than the vacuum VC2n capable of judging that the ash in a pipe at the downstream side of the No.(n) set has been emptied, ash in the pipe 4 between set No.n-1 and No.(n) is handled. Afterward similar operation takes place for the set at the upstream side in order.

Title: Motive power reutilization equipment for vehicle with engine
Inventor: NAITOU NORITAKA
IPC: F02B77/14
Filed: 1981-05-29
Abstract: PURPOSE:To heighten the efficiency of deceleration, braking and acceleration of a vehicle, by changing kinetic energy into electric power and temporarily storing it in a battery in the deceleration or/and braking, and using the electric power to assist the rotation of the engine of the vehicle in its acceleration. CONSTITUTION:An electric motor M and an electricity generator G are coupled to the output shaft 1 of an engine E through transmission units 4, 5. A one-way clutch 6 transmits torque in only one direction from the motor M to the engine E. In the deceleration or braking of a vehicle, a controller C makes a charging circuit 8 so that electric power produced by the generator G is stored in a battery B. In the acceleration of the vehicle, the controller C makes an electricity supply circuit 7 so that the electric power stored in the battery B is supplied to the electric motor M to apply auxiliary torque to the output shaft 1 through the transmission unit 4. The efficiency of the deceleration, braking and acceleration is thus heightened.

Title: Rear wheel steering device for front and rear wheel steering car
Inventor: KOIKE SHIN
IPC: B62D7/15
Filed: 1988-04-04
Abstract: PURPOSE:To prevent protrusion of rear wheels and the rear side part of a car body to the outside during the starting of a vehicle, by a method wherein, in a front and rear wheel steering car, rear wheels are steered with a lag in a time after the starting of a vehicle. CONSTITUTION:When front wheels FW1 and FW2 are steered, a steering amount of a front wheel is converted into an oil pressure by means of a hydraulic converting mechanism B1, a converted oil pressure is transmitted to a rear wheel steering mechanism B3 through a pair of oil passages P1 and P2, and the rear wheel steering mechanism steers rear wheels according to the transmitted oil pressure. In this case, if a vehicle is in the middle of a stop, a hydraulic pump 31 does not deliver working oil. Since a second valve means intercommunicates a pair of oil passages P3 and P4, first and second oil pressures transmitted to the rear wheel steering mechanism are made equal to each other, and rear wheels are not steered. After a vehicle is started, the hydraulic pump 31 starts to deliver working oil, but since intercommunication of a pair of oil passages is gradually prohibited by second valve means 32 and 33, rear wheels are steered with a lag in a time after the starting of a vehicle.
