Title: Exhaust reflux system for internal-combustion engine
Inventor: SADAKATA HIROSHI
IPC: F02M25/07
Filed: 1983-03-17
Abstract: PURPOSE:To aim at the continuous control of a reflux rate without using a solenoid valve or the like, by controlling an exhaust reflux control valve via a suction control valve interlocking an accelerator, while keeping a constant exhaust reflux rate in time of low load but in time of high load, reducing the reflux rate to some extent. CONSTITUTION:When an accelerator is stepped on, in time of low load, engine speed increases, making the opening of a throttle 22c wider, and a valve housing 15 rotates as far as the same phase in the same direction as a screw adjuster 14a whereby this adjuster 14a fails to enter the inside of a cap body 14, thus constant suction pressure is led into an exhaust reflux valve's suction chamber 4b. On the other hand, in time of high load, the engine speed remains unincreased and since a throttle shaft 22b will not rotate so much, the adjuster 14a enters the inside of the cap body 14, causing the set position of a diaphragm 16 to go down to some extent so that suction pressure to be led into the reflux control valve's suction chamber 4b via a suction pressure control valve 21 and a suction pressure chamber 15a becomes decreased, and the lift of a valve body 4a therefore decreases, thereby decreasing the exhaust reflux rate as well. Accordingly, the exhaust reflux rate can be controlled over the whole range of drivability continuously and stepwise.

Title: Television camera unit
Inventor: OKUHARA MITSUHIKO
IPC: H04N5/262
Filed: 1979-04-16
Abstract: PURPOSE:To prevent picture quality degradation by holding the level of the modulated video signal from a camera head fixed by a variable gain control amplifier. CONSTITUTION:The modulated signal which includes the synchronizing signal and is dependent upon the video signal with the modulation degree of the black level part fixed is generated from camera head 1 and is transmitted to camera controller 2 through cable 3. In controller 2, this modulated signal is led into variable gain control amplifier 10, and the synchronizing signal is extracted through detector 11 from the output. This synchronizing signal is controlled by automatic phase control synchronizing circuit 16. This synchronizing signal is supplied to gate signal generating circuit 17 to generate a gate pulse corresponding to the black level part of the video output. The detection output is gated by this pulse, and amplifier 10 is controlled by the output. Thus, the level of the modulated video signal is held fixed, so that degradation of the picture quality can be prevented.

Title: Condensor
Inventor: SHIMADA YOSHIO
IPC: F28B1/02
Filed: 1983-03-22
Abstract: PURPOSE:To enhance the vapor condensation capability of cooling pipe as a whole and to reduce the pressure loss so that the condensation performance may be improved by providing a flow speed distribution generator at a cooling water inlet in order to generate a cooling water flow speed distribution. CONSTITUTION:The piping arrangement of a condensor is such that it is sparsely arranged in an outer sparse arrangement section 8 and is densely arranged in an inner dense arrangement section 9. Therefore, the cooling water which is made to flow fast in its outer area and slower in the inner area flows in such a manner that the cooling water in the outer area flows into the outer sparse arrangement section 8 and the cooling water in the inner area flows into the dense arrangement section 9 at corresponding speeds. Because of this, the heat conductivity in the sparse arrangement section 8 is improved. As for the dense arrangement section 9, since the transmission rate is poor outside the piping, the overall heat transmission rate is not so poor as might be expected. As the vapor condensation capaility is improved in the sparse arrangement section 8, the overall performance of the condensor is improved, and a condensor with a less pressure loss can be obtained.

Title: Annular motive power transmitting body and heat treatment method thereof
Inventor: KITA AKIHIKO
IPC: C21D1/10
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To shorten treating time and to improve the productivity of a heat treatment apparatus. SOLUTION: An annular motive power transmitting body receives the motive power in either one surface of an inner peripheral surface S2 and an outer peripheral surface S5 and transmits the power to the other surface. On the former surface, an induction heating treatment at the temp. of the austenitc transformation point or higher and an induction hardening treatment with rapid cooling are applied, and on the other surface, the induction heating treatment is applied. In this case, since not only the temp. on the former surface of the annular motive power transmitting body, but also the temp. in the inner part thereof can be made sufficiently high, the hardened depth can be made deep.  Therefore, since not only the hardness on the one side surface of the annular motive power transmitting body, but also the hardness in the inner part thereof can be made high, the annular motive power transmitting body is prevented from fatigue breakage caused by the internal stress.
