Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To reduce the fusion of stem glass in discharge by inserting a first and second lead wires, respectively, into a first and second holes which are formed in an insulator and have cross-sectional areas larger than those of the first and second lead wires. SOLUTION: An end of an arc tube 1 is sealed by a flare stem 2. An insulator 5 in which two holes are drilled is so installed on the flare stem 2 as to cover a glass part between sealing parts of a pair of inside lead wires 3a, 3b. The insulator 5 is loosely fixed by expanding the distance between the lead wires as the pair of inside lead wires 3a, 3b approach the side of a filament 4. The cross-sectional areas of the holes formed in the insulator 5 are preferably 1.2-10 times as much as those of the inside lead wires 3a, 3b. In addition, if the cross- sectional shapes of the holes and the lead wires are circular, their cross-sectional area ratio is preferably 1.1-3.3. Thereby, the mounting workability of the insulator to the stem in mass production is improved and the abnormal sound produced by the play of the insulator can be avoided.

Abstract: PURPOSE:To improve the starting property of an engine by providing a suction heating heater on the downstream side of a suction control valve for heating the suction heating heater prior to the starting of the engine to heat the air inside a suction passage. CONSTITUTION:When an engine key is inserted into a key hole prior to the starting of a Diesel engine, current is supplied to a suction heating heater 9 to generate heat. Since an accelerator pedal is not stepped on a this stage usually, a suction control valve 6 is at a completely closed position, and therefore the air in a closed space between it and a suction valve of the Diesel engine 1 is efficiently heated by the suction heating heater 9. When the Diesel engine 1 is started, the air heated in the space is introduced into a combustion chamber of the engine in accordance with the opening of the suction valve. When liquid fuel is injected from a fuel injection valve into the combustion chamber of the engine containing this heated air, fuel can be smoothly ignited.

Title: Switching regulator
Inventor: NOJI HIDESHI
IPC: G05F1/56
Filed: 1983-07-25
Abstract: PURPOSE:To improve the reliability by adding a voltage clamping diode to a transformer connected to a commutation diode, thereby reducing the loss at the turning OFF time. CONSTITUTION:A switching regulator is composed by connecting in series a switching transistor (referred to as Tr) 1, an output choke coil 3 and an output capacitor 4 with a DC power source 5, and a desired output voltage VO is obtained by controlling ON and OFF the Tr1. In this case, a transformer 11 and a voltage clamping diode 12 are provided. When the Tr1 becomes ON at the turning On time, the collector current IC increases, the current ID of a commutation diode decreases, and the primary voltage VT1 of the transformer is generated. This is suitably selected, equalized to the input voltage VIN to set the VEC of the Tr1 to zero. The voltage VT2 generated at the secondary coil at the turning OFF time is clamped by the output voltage VO when the diode 12 becomes ON.

Then a clock circuit 5 connects a measuring start circuit 7 to a power battery 6 to start measurement of used city water amount daily at intervals of several times per several minutes in mid night time zone in which city noise is less generated. In addition, a measurement control storing circuit 8 stores the measured results of the measurement start circuit 7 and, when water leakage is judged to occur, water leakage is displayed on a water leakage display part 9. This water leakage display is made by reversing a colored display plate using a magnet in order to reduce the consumption of the power battery 6.
