Abstract: PURPOSE:To enable the setting of a large distance between the discharge part of a main electrode and an internal combustion engine body as a grounding body, and raise discharge start voltage for reducing discharge maintenance voltage by specifying a distance between the discharge part of the main electrode and the inner wall of an enclosure. CONSTITUTION:A gap G between main electrodes 2 and 5 is set at 5 to 12 mm and a xenon gas of 99% or more purity is sealed in a cylindrical enclosure 1 under the gas pressure of 6.5 to 20 atm. In addition, a relationship between the gap G and a minimum distance D between the discharge part of the main electrodes 2 and 3, and the inner wall surface of the cylindrical enclosure 1 is taken as 0.2XG<=D. Furthermore, the gap G and the gas pressure is taken within 5 to 12mm or 6.5 to 20atm so that discharge start voltage will be within a range of 18 to 25kV. According to the aforesaid construction, the discharge start voltage becomes 18kV or more and the discharge maintenance voltage is considerably reduced to as small as 1/80 of the discharge start voltage, thereby ensuring the prevention of internal combustion engine smoking due to the fouling of an ignition plug with a small amount of energy.

Title: Manhole cover structure
Inventor: TSUKIOKA TOSHIO
IPC: E02D29/14
Filed: 1992-05-10
Abstract: PURPOSE:To facilitate the transit of a snow removing plate by forming the upper face of a manhole cover lower than the top of a manhole cover receiving frame. CONSTITUTION:A manhole cover 9 is stored in a cover storing hole 7, and the upper face 11 of the cover 9 is formed lower than the top 3 of a manhole cover receiving frame 1. Since the upper face 11 of the cover 9 is formed lower than the top 3 of the cover receiving frame 1, the cover 9 is not largely protruded from the top 3 of the cover receiving frame 1 even if the cover 9 is lifted or inclined by the occurrence of rust on the cover 9 or the infiltration of sediment. When the snow removing plate 1 passes through the front end of the cover receiving frame 1, it is not hooked on the cover 9, and the transit can be facilitated.

IPC: H03F3/345
Filed: 1982-08-20
Abstract: PURPOSE:To actuate a semiconductor IC with a low level of current, by cascading three tiers of FETs having small gate width and then applying a negative feedback to the gate of the 1st tier from the drain of the 3rd tier by a resistance. CONSTITUTION:A high-impedance connection is given between FET1 and 2 as well as FETs 2 and 3 with insertion of coupling capacitors 10 and 11 respectively. As a result, the gain of each FET increases. Furthermore the open loop gain can be increased more owing to the three-tier cascade. Thus the open loop gain is increased greatly up to about 60dB when the gate width of the FET is set at each value shown in a table. As a result, it is possible to increase the feedback resistance up to 8OMEGA to obtain the input/output matching. Thus, the overall gain can be increased up to about 30dB.
