Title: Cold/hot air generator
Inventor: KATO SHIGERU
IPC: F25B9/00
Filed: 1988-03-24
Abstract: PURPOSE:To enable cold and hot air to be generated, respectively, making use of a centrifugal compressor alone, by allowing compressed air to rotate a turbine rotor after cooling and by reducing air flow to expand air, thereby reducing the pressure of air without lowering its temperature. CONSTITUTION:A motor 1 rotates a centrifugal compressor 10 with the aid of a shaft 2. When a damper 9 is opened, high-temperature and high-pressure air generated by the rotation of the centrifugal compressor 10 passes through a heat exchanger 8 to be converted into low-temperature and high-pressure air, and is ejected out of a nozzle type fine hole 6 after passing through a compressed air chamber 7. The ejected air changes its direction by a baffle plate 18 and impinges against a turbine blade 17 to rotate a turbine rotor 5. If the rotation of the turbine rotor 5 is braked by a water-cooled controller 4, the energy of an ejected air speed is converted into frictional heat to be taken out to the exterior together with cooling water, and the air is cooled to be discharged. When the damper 9 is closed and a damper 19 is opened, the high-temperature and high-pressure air flows inside a choke tube 11 to be led to an exhaust tube 12 and moves a cylindrical regulating valve 13 pressed with a spring 14 to be discharged through an exhaust port 20. The throttle tube 11 is formed into a triple turn passage through which air flows. Accordingly, air flow is repeatedly inverted to be reduced, and consequently the pressure of air is lowered without the change of its temperature, and the air is converted into utilizable hot air.

IPC: B22D17/32
Filed: 1986-03-28
Abstract: PURPOSE:To make it possible to substantially detect the resin pressure in a molding cavity by using a mold with a dummy cavity, in which molten resin can be injected and filled similarly as in molding cavities and which is arranged side by side with the molding cavities, and with a resin pressure detector, which is installed in said dummy cavity. CONSTITUTION:In a mold 1, a sprue 3 and a plurality of mold impressions 6 and one dummy mold impression 7 communicating through runners 4 and edge gates 5 to the sprue 3 are provided. One end side of a pressure detecting pin 13, the other end of which is retreatably fitted to an ejector plate 12, is fitted movably to and fro in the same manner as ejector pins 11 in a movable mold 8 at the position corresponding to the dummy mold impression 7. Because the resin pressure in the mold cavity can be detected indirectly by the structure as mentioned above, the accuracy of resin pressure control during injection filling or dwelling process is improved and consequently the scattering in quality of molded item can be reduced.

Abstract: PURPOSE: To reduce the channel effect caused with reduction of the channel length by providing the intermediate layer of a low impurity density between the semiconductor substrate and the source/drain region of a high impurity density in order to secure the double-layer structure for the source/drain region.  
     CONSTITUTION: N - -type layer 2 is epitaxial-grown on P - -type Si substrate 1, and mask 3 of the resist film is coated on the formation region of the transistor with the etching applied to remove the both end parts of layer 2. Then P-type field region 4 is formed by the ion inplantation at the both end parts of substrate 1 which are exposed with removal by the etching, and region 4 is then covered with thick SiO 2  film 5. After this, film 3 is changed into SiO 2  film 6, and the window is drilled at the gate formation region with implantation of P-type ion there in order to form P + -type channel region 7. Film 6 is then removed, and gate SiO 2  film 8 and poly-crystal Si film 9 to be changed into the gate electrode are grown over the entire surface of the substrate with the opening drilled. Then shallow N + -type source and drain regions 10 and 11 are formed by diffusion at both sides of region 7.

Title: Swash-plate type compressor
Inventor: KAWASHIMA KENICHI
IPC: F04B39/02
Filed: 1978-06-14
Abstract: PURPOSE: To restore lubrication speedily at the time of staring operation by providing a lubricant holding unit on the inner wall of a swash-plate chamber.  
     CONSTITUTION: Lubricant which is scattered in the axial direction by its movement in the axial direction due to the rotation of swash plate 5 reaches the inner wall surface of swash plate chamber 4 of cylinder block 8 and flows into narrow hole 13. The lubricant which has flowed into the hole is in the state of being shut from the air pressure due to the movement of swash plate 5 in operation or the effect of the flow of the coolant so that it is held in the hole. On the other hand, when the operation is stopped, the lubricant held in narrow hole 13 flows down from the opening along the inner wall surface of swash plate chamber 4 and settles at the bottom of the chamber. Consequently, the lower part of swash plate 5 is immersed in oil and lubricated even when the operation is stopped for a long time. As a result, it is possible to form a sufficient lubricant film by a single rotation.

Title: Control method for internal combustion engine using oxygen density sensor, device therefor and internal combustion engine therewith
Inventor: MUKUMOTO KYOJI
IPC: G05B11/36
Filed: 1995-03-29
Abstract: PURPOSE: To reduce computation time in a device where fuel injection control to rich and lean sides is repeated according to an output of an O2 sensor provided on a reference cylinder by controlling the fuel injection amount, in other cylinders, based on a control rate at an inversed position with respect to the reference cylinder. CONSTITUTION: In O2 feedback control, fuel infection in order to obtain a rich state is performed first. When an A/F exceeds a target value and an output voltage of an O2 sensor 14 reaches V1, controlling is switched from a rich to a lean direction. Injection is performed to obtain the lean state. A correction factor is reduced every specified period for reducing an injection amount. When the A/F is less than the target value and an output voltage of the O2 sensor is V, controlling is switched from a lean to a rich purpose. With respect to other cylinders #2 to #6, representative value is calculated from a correction factor of adjacent switching points. A constant amount of fuel is injected based on the representative value.

Abstract: PURPOSE:To improve the efficiency of a rolling operation by regulating the circumferential speed of a non-driven floating roll installed near driving rolls disposed with a spacing between the rolls to the speed higher than the circumferential speed of the inlet side driving roll and lower than the circumferential speed of the outlet side driving roll. CONSTITUTION:The large-diameter driving rolls 1, 2 and the non-driven floating roll 3 of the diameter substantially smaller than the diameter of the respective driving rolls 1, 2 on the line slightly off the axial center plane of the two driving rolls 1, 2 are disposed. The circumferential speed of the floating roll 3 and the circumferential speeds of the driving rolls 1, 2 are directly measured by a circumferential speed detector 10. The tensions on the inlet side and outlet side are so regulated that the circumferential speed of the floating roll 3 is kept always higher than the circumferential speed of the inlet side driving roll 1 and is lower than the circumferential speed of the outlet side driving roll 2 even if there is a fluctuation in the circumferential speed of the floating roll 3.
