Title: Automobile air conditioner
Inventor: ONO MASATO
IPC: B60H1/32
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To cool a propulsion motor as a propulsion source of an automobile or a propulsion motor driving unit and to avoid the increase of load of a compressor in a refrigerating cycle. SOLUTION: A calculation control unit 7a of a detour control unit 7 receives a temperature detecting signal from a temperature sensor TS, increases the detour amount of refrigerant discharged from an expander 13 to a bypass passage (a) by releasing an opening and closing valve a1 when load to be applied to a vehicular propulsion motor 502 is increased, and enhances cooling capabilities in a refrigerant pipe 15a. While, when the travel of the automobile is returned to the cruising travel and load is decreased, the detour amount is reduced to restore the cooling effect in a compartment. Therefore, the automobile propulsion motor 502 and a propulsion motor driving unit 503 can be cooled, and the increase of compressor load can be avoided.

Abstract: PURPOSE:To obtain a video signal having wide dynamic range and a large amount of information with a simple constitution, by arranging a filter in an X-ray passing area in the stage before a image pickup tube. CONSTITUTION:An X-ray emitted from an X-ray tube bulb 1 permeates an object 2 and makes incident to an X-ray image amplifier 3 to convert the X-ray permeated image of the object 2 to the image of visible light. The image of visible light is fed to an image pickup tube 5 through an optical system 4 and converted to a video signal. If the video sigal is directly transmitted to a television monitor 6, the X-ray permeated image is displayed on its screen as it is. A thin film like filter 7 is inserted between the object 2 and X-ray image amplifier 3, or between the X-ray tube bulb 1 and object 2. The filter 7 is made by forming many slit like long and narrow open parts on the film of materials such as Pb, W and Au which attenuates the X-ray.

Filed: 1985-04-30
Abstract: PURPOSE:To facilitate the maintenance of a device and to prevent the occurrence of slippage by using infrared rays from an auxiliary heat increase source only for the heating process of a substrate. CONSTITUTION:The heat is mainly obtained from a high-frequency induction heater in which a susceptor 5 is used.

Thus, it is made possible to transfer the substrate 6 from a elastic state to a plastic state while making the temperature distribution within the susceptor 5 and the surface of the substrate 6 supported by it uniform, thereby preventing the occurrence of slippage. Moreover, it is possible to increase the lifetime of an auxiliary heat source such as a lamp 2 since no auxiliary heater during the vapor growth where reaction gas is flown.

Title: Production of laminated glass
Inventor: HAYASHI SATOSHI
IPC: C03C27/12
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To easily obtain a transparent laminated glass using an interlayer consisting mainly of an ethylene-vinyl acetate copolymer by performing a cooling process at a specified cooling rate so as to set laminating conditions without altering the resin composition. SOLUTION: For example, when this laminated glass is to be produced through the process to make a laminate such as glass plate/interlayer/polymer membrane/interlayer/glass plate, deaeration process, heat treatment process and cooling process, the laminate is cooled at a rate of >=2.5 deg.C/min (pref. >=4.0 deg.C/min) in the cooling process. In this cease, the cooling rate can be calculated, for example, by sticking a thermocouple sensor on the laminate glass surface to measure the surface temperature and using the measurement together with cooling time. By quenching, the crystal in the resin converts to microcrystal, leading to lowering degree of crystallinity; that is, the crystallite size in the resin becomes smaller than the wavelength of visible rays, resulting in cloudiness of the resin, thus affording the laminated glass with transparency.

Title: Ac motor speed control device
Inventor: MIYAMOTO TAKAO
IPC: H02P23/06
Filed: 1979-07-25
Abstract: PURPOSE:To stabilize the operation of an AC motor in low load by varying the polarity of deviation between a command value and an inverter output according to the driving and the regenerative times so that in either case the ratio of the output voltage of the inverter to the frequency is constant. CONSTITUTION:An output from a discriminator 45 closes the switch 47 of a switching circuit 44 at driving time, the output from an operational amplifier 42 is compared directly with the output of a command circuit 34 by an arithmetic unit 53 to close the switch 46 at the regenerative time and to compare the output of the amplifier 42 with the reverse polarity through the polarity inverter circuit 43 to that at the driving time. When the voltage and the frequency in ratio is increased due to the load variation, the output of the arithmetic unit 35 for controlling the current is always positive. Accordingly, the switch 47 is closed to cause the output of the amplifier 43 to become negative to increase the input of the voltage-to-frequency converter 38 so as to increase the frequency of an inverter 28. In the case of regeneration, the ratio becomes larger to cause the output of the arithmetic unit 36 to become positive. Accordingly, it causes the output of the circuit 43 to become positive to reduce the frequency of the inverter 28.

Abstract: PURPOSE:To improve reliability for holding a recording material of a transfer drum by providing each separate driving source on the transfer drum and a recording material carrying means, simplifying a special control required for the recording material carrying means, and simplifying a mechanism of a carrying means. CONSTITUTION:A recording material holding transfer body and a recording material carrying means are provided with a driving source which is controlled independently, respectively. When a gripper 24 is positioned at a' (a'<a) which is a little shorter than a distance (a) extending from a holding point A to the second resist roller 21, the second resist roller 21 is rerotated. Subsequently, when the gripper 24 comes to the holding point A, a transfer drum 22 is stopped in a state that the gripper 24 is opened. The time when the transfer drum 22 stops and a transfer paper P comes to the holding position A becomes (a-a')/V, the transfer paper P is fed in a state that the gripper 24 is opened, and it hits against the gripper 24. The transfer drum 22 rotates again, when the tip of the transfer paper P hits completely against the gripper 24, and becomes a parallel state to a bus of the transfer drum. In this way, the reliability for holding the transfer paper of the transfer drum is improved.

Filed: 1985-04-30
Abstract: PURPOSE:To switch >=3 diffraction gratings easily with high accuracy by energiz ing a cam and a lever for locking in press-contacting directions and securing the engagement between the cam and lever. CONSTITUTION:A turntable 1 where diffraction gratings G1-G4 are fitted has a rotating part united with it as a cam and engages the lever 9 for locking. The turntable rotates in one direction, but the cam and locking lever 9 engages each other at specific positions of the respective diffraction gratings G1-G4 and the turntable is stopped from rotating in the opposite direction, so the diffraction gratings G1-G4 are positioned by the locking lever 9 and held there. At this time, a driving motor 6 couples elastically with the turntable 1 and is reversed where the lever 9 engages one of recesses N1-N4 to charge its driving force in an elastic coupling means. Consequently, there is no play in positioning, the positioning accuracy is high, and the precision required to switch the diffraction gratings G1-G4 is easily obtained.
