Title: Noise shielding apparatus for variable cylinder number type engine
Inventor: KURODA KAZUYUKI
IPC: F02B77/13
Filed: 1982-09-20
Abstract: PURPOSE:To prevent generation of intake blasting noise by installing an intake/exhaust valve operation detecting means onto a cylinder quantity controlled engine and allowing the stop of operation of an intake valve to precede during transition to the reduced- cylinder operation and allowing restoration of operation of an exhaust valve to precede during restoration to the whole-cylinder operation. CONSTITUTION:An intake valve operation sensor 21 is installed onto the locker arm 3 of an intake valve 2, and a cam nose sensor 22 is installed onto a cam 10, and an exhaust valve operation sensor 23 is installed onto the locker arm 13 of an exhaust valve 12, and the signal of each sensor is input into a calculation circuit part M. When a cylinder quantity controller 1 transmits a reduced-cylinder signal ''H'', the hydraulic tappet 5 of the intake valve is loaded onto the base dia 10b of the cam 10, and if lift is not performed, a solenoid valve 9 is first turned ON, and the hydraulic tappet 5 is put into inoperative state, and the intake valve is kept in closed state, and afterwards suspension of operation of the exhaust valve is permitted. Since the exhaust valve does not stop operation before the intake valve stops operation, generation of the noise due to blasting intake gas in the case when the cylinder quantity is varied can be eliminated.

Filed: 1981-10-12
Abstract: PURPOSE:To improve manufacturing process and to decrease manufacturing cost largely, by a method wherein a photoreceiving element is coated with resin which scarcely absorbs light in the visible range comprising organic near-infrared absorbent therein. CONSTITUTION:A thin film having the function to cut near-infrared ray is formed by solution including organic near-infrared absorbent and resin which scarcely absorbs light in the visible range by utilizing a method such as potting, on a light-receiving element or a light-receiving element molded by said resin, so that the light-receiving element itself has the function to cut near-infrared ray. Metal complex salt and organic salt are suitable as the organic near- infrared absorbent. As the resin which scarcely absorbs light in the visible range, any visible ray transmitting resin which permits light within visible range to transmit therethrough is possible, such as acryl resin, silicone resin, polycarbonate resin, and PVAL.

Title: Safety device for air conditioner
Inventor: KANAZAWA HIDETOSHI
IPC: H02P27/06
Filed: 1993-06-30
Abstract: PURPOSE:To make it possible to prevent the failures of electric components even though there are some errors in connections of power supply terminals and neutral terminals to an AC power supply by interrupting the uptake of a voltage exceeding a predetermined value applied between the power supply terminal and neutral terminal. CONSTITUTION:Let's consider a case where there is an error in the connection between an AC power supply 1 and an outdoor unit 3 with a neutral terminal N being connected to a T-phase of the AC power supply 1 and a power supply terminal T being connected to a neutral terminal of the AC power supply 1. In this case, a voltage of 240 V, which is lower than the original voltage of 415 V, is applied between terminale R and T and between terminals S and T, and also a voltage of 415 V, which is higher than original voltage of 240 V, is applied between the terminals R and N. This voltage of 415 V between the terminals R and S is applied to a varistor 22 and a relay 21. At this time, the varistor 22 suddenly reduces its resistance resulting in a flow of a large current through the varistor 22 thereby instantly melting a fuse 20. By this melting, the relay 21 ceases its operation. Thus, the applying of the voltage of 415 V to a control portion 15 can be avoided.

In this case, output of differential amplifier circuits 31A, 31B is 'H' and TN6 is in the on state, a voltage of the output node C is rapidly lowered. When the voltage of the output node C becomes lower than the predetermined value, thereafter TN6 becomes always off state and PT1 turns on to output the predetermined output voltage VOUT.

Title: Controller for electric rolling stock
Inventor: EMOTO TAKASHI
IPC: B60L7/22
Filed: 1986-07-11
Abstract: PURPOSE:To eliminate a voltage detector by utilizing as a motor voltage the voltage generated from simulating voltage generating means for simulatively generating a voltage when a motor is regenerative at the time of switching the series connection as a light load is regenerative. CONSTITUTION:A comparator CMP1 compares a regenerative brake command VBP with a real brake force VB to decide the conduction rate gamma of a field chopper. When it becomes a reference voltage VES < detecting voltage VEL, a trolley wire limiter operates to apply its differential voltage to the comparator CMP1 to reduce the conduction rate gamma of the chopper. As a light load regeneration is detected when a series connection is switched, a logic circuit LG detects it to close a switch SW, and the difference between the simulating trolley wire voltage VEL from a simulating voltage generator VG and the voltage VEL is applied to the comparator CMP1.
