Title: Compression ignition type internal-combustion engine
Inventor: YASUHARA SHIGEFUMI
IPC: F02M25/07
Filed: 1978-10-19
Abstract: PURPOSE: To conduct exhaust gas reflux (EGR) in a low-load low-revolution operation range of a compression ignition type internal-combustion engine and to reduce knocking and vibration of the engine by communicating suction and exhaust passages of the engine by an EGR passage fitted with an on-off valve and opening the valve fully in the operation range.  
     CONSTITUTION: Suction and exhaust pipes 1 and 2 of an engine are communicated by an EGR passage 4 fitted with an on-off valve 6. A control lever 8 of a fuel injection pump 7 is provided with a position detector switch 9 which contacts the lever 8 when the opening of the lever 8 exceeds a predetermined degree. With the lever 8 in contact with the switch 9, solenoid valves 3a and 6a are driven, and a throttle valve 3 in the pipe 1 and the valve 6 are operated. In a low-load low- revolution operation of the engine, the valve 3 is closed and the valve 6 opened, and EGR is conducted. Since a sufficient amount of oxygen is contained in the exhaust gas in this operation range, knocking or the like is reduced effectively and engine  stability is kept high irrespective of EGR.

Title: Circular fluorescent lamp and lighting system
Inventor: OSAWA SHIGERU
IPC: H01J61/067
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To prevent damage to a phosphor layer in manufacturing and to prevent discoloration of a phosphor. SOLUTION: In this fluorescent lamp, a height of a mount M1 of a first electrode 4A enclosed in one end side of an elongated translucent discharge vessel 1 of a tube diameter of 14-18 mm is set to a larger value than a height of a mount M2 of a second electrode 4B enclosed in the other end side. The translucent discharge vessel 1 is circularly bent by winding the discharge vessel 1 around a rotating drum with one end of the discharge vessel 1 on the first electrode side disposed on the fixed side and with the other end thereof disposed on the winding side, is exhausted through a capillary 3A projecting from one end of the translucent discharge vessel 1, is charged with an ionization medium, and is tipped off. A tip-off part 3A1 is recessed into the capillary 3A.  Because the exhausting and charging can be executed on the fixed side in time of the winding, the electrode 4B hardly approaches the inner face of the translucent discharge vessel 1 even if a position of the electrode 4B is shifted at the time of the winding, to reduce generation of trouble such as damage to a phosphor layer or discoloration of a phosphor caused by heat from the electrode 4B. Because the capillary 3A or one end can be formed with a desired coolest part, luminous efficiency is improved.

Title: Tire and surface treating method of tire
Inventor: FURUYA KENGO
IPC: B29D30/00
Filed: 1989-05-23
Abstract: PURPOSE:To surely prevent the slip of tires while driving on the road surface covered with ice and snow without requiring any special outfitting by forming flame-coated metallic membrane over the part of tires coming into contact with road surface, in part or the whole. CONSTITUTION:Flame-coated metal membranes 3 of Zn, Al, etc. are formed on the part of a tire 1 coming into contact with road surface, with grooves formed thereon. For an example, a flame-coating metal is flame-coated on part or the whole of the part of the tire 1 coming into contact with road surface by low-temperature flame-coating like an arc flame-coating. Physical treatments such as metal mold forming, blasting and grinding, or chemical treatment with pretreatment agents before flame-coating may be given in the flame-coating. Giving such treatments, flame-coating is easily performed again after the flame- coated membranes were worn away with the running of tires, not only for the flame-coating for new tires. Consequently, tires 1 can be surely prevented from slipping when running over road surface covered with ice and snow without requiring any special outfitting.

Title: Holding tone sending controller for electronic exchange or the like
Inventor: FUJITA HIROSHI
IPC: H04M19/02
Filed: 1986-06-04
Abstract: PURPOSE:To attain sure holding tone sending control by allowing a central control unit to check the content of a terminal state storage device every time a periodic interruption generator applies interruption to the central control unit and stopping a holding tone sender only when the holding terminal does not exist. CONSTITUTION:When a start signal is received, a holding tone sender 4 disregards it if it is started already and applies actual starting if it is stopped. The central control unit 2 controls a channel to connect the holding tone sender 4 and a terminal. If there is a terminal whose holding is released, the central control unit 2 detects it to rewrite the content of the terminal state storage device at the terminal from the state (e.g., talking) transited from the holding state. When an interruption is generated from a periodic interruption generator 5, the central control unit checks the content of the terminal state storage device 6 of all the terminal equipments and when no terminal in the holding state exists, a stop signal is sent to the holding tone sender 4. When the stop signal is received, the holding tone sender 4 disregards it if it is stopped and stops the device if it is started.

Title: Detector for choking of nozzle for spray gun
Inventor: TANIGAWA YASUO
IPC: B05B15/02
Filed: 1980-09-19
Abstract: PURPOSE:To monitor choking of a nozzle without producing a change and an interference from the outside, by a method wherein a change in a sound wave signal of a jet sound from a nozzle is always monitored. CONSTITUTION:A paint 3 in a tank 2 is fed by pressure to a spray gun 1 via a valve 8 and a line 9 by means of a pump 5 driven by high-pressure air from an air source 6, and is jetted through a nozzle 12. A microphone 13 picks up a jet sound produced through the nozzle 12, and feeds it to a filter 16. The filter 16 causes only a set frequency band to pass, and an amplifier 17 generates an output voltage V proportional to a sound volume. If a reference voltage Vs of a reference voltage generating circuit V is set so that it is lower than an output voltage V at a normal painting time or at the time when there is no choking of a nozzle, the voltages are brought into Vs<V at the normal painting time, and a comparison circuit 18 generates no output. If the nozzle 12 is choked, and paint is reduced in a jet amount, a sound wave signal is decreased in a sound volume, and the amplifier 17 is reduced in the output voltage V. Thus, when the voltages are brought into Vs> V, the comparison circuit 18 outputs a nozzle choke detecting signal, and actuates an alarm circuit 15 and the like via an output circuit 20.
