IPC: G01R31/06
Filed: 1990-07-31
Abstract: PURPOSE:To enable the detection of aging of insulation of a ground coil beforehand by providing at least more than one high frequency current transformers on a earth wire of the ground coil to connect the secondary side thereof to a differential amplifier. CONSTITUTION:A coil conductor 2 is covered with an insulation layer 3 and a high frequency current transformer 9 is disposed on an earth wire 8 for connection between earth layers of a ground coil 1, which is provided with the earth layers on the surface thereof. When outputs of at least more than current transformers 9 are connected to a differential amplifier (D. AMP) and an HPF, currents i1, and i2 flow to the current transformers 9 having a current associated with a frequency component of an operation voltage overlapping a current of a pulse-like high frequency component accompanied by an aging of insulation. When the currents are inputted into the D.AMP, as an electrostatic capacitance of the coil 1 is almost equal in capacity, the current corresponding to the frequency component of the operation voltage is canceled to be almost zero and the pulse-like high frequency component alone is left, so that the current is associated with the aging of the insulation is detected from HPF. This enables the detection of the aging of the insulation of the coil 1 beforehand thereby achieving a rationalization of manufacture and higher safety of the operation of a vehicle.

Title: Data server
Inventor: NISHIZAWA HIROSUMI
IPC: G06F11/16
Filed: 1995-08-08
Abstract: PROBLEM TO BE SOLVED: To reduce the load on a program while making sure of performing data equivalent processing by the completion notification of data collection processing by performing the synchronization of collection completion of data and the equivalent management of the data by an independent duplexed link program. SOLUTION: The duplexed link program 4 receives notification when a data collection program 1 has completes the data collection processing at each collection timing, and monitors the completion of the data collection processing between both computers by such notification, and notifys a file equivalent program 3 of a data equivalent request. Therefore, the data collection program 1 becomes for only notification of the completion of data collection to the duplexed link programs 4 instead of the request of data equivalence being conscious of an equivalent timing to an existing file equivalent program 3, which eliminates the mutual monitoring of completion of the processing by the data collection programs and relaxes the load on them.

Title: Sand protecting and breakwater dam
Inventor: MORITOMO YUKIO
IPC: E02B3/06
Filed: 1982-11-19
Abstract: PURPOSE:To completely prevent the scattering of sand and force of tidal wave on the coastal line or at the position of the dam by forming a curved line permitting the utilization of its dynamical characteristics on the seaside wall of a dam. CONSTITUTION:The seaside edge line 4 of the vertical cross section of a dam 1 is shaped into a curved form such that a gentle rise from the horizontal face is changed to vertical form toward the inland direction and the vertical form is curved with gradually reducing radius and ended before heading for the lower part of the vertical section. By such a curved line, the force of tidal waves is raised along a smooth curve according to the water level and energy, changed into potential energy, and then dropped. Since the falling sea water serves as forces in the opposite and right-angled directions to the following tidal waves, the tidal wave force is damped by itself and the reach of the tidal waves onto road can be avoided.

Title: Field effect transistor and manufacture thereof
Inventor: KOSHIZUKA YASUO
IPC: H01L29/78
Filed: 1991-07-18
Abstract: PURPOSE:To prevent the deterioration of drain breakdown strength even if a gate length is made small by forming a source region film and a drain region film comprising non-single-crystal silicon containing impurities in trenches, thereby forming the shallow source region film and drain region film. CONSTITUTION:Non-single-crystal silicon films 28 and 29 are deposited in trenches 25 and 26, which are formed at parts where a source region and a drain region are to be formed at the surface side of a silicon substrate 21. Thus, a depth xj of the non-single-crystal silicon films 28 and 29 is governed by the depth of the trenches 25 and 26. Therefore, when the depth of the trenches 25 and 26 is made shallow, the depth xj of the non-single-crystal silicon films 28 and 29 can be made shallow. Thus, the extension of the depletion layer from a drain region film 31 into the lower part of a gate electrode 24 is suppressed, and the short-channel effect can be lowered to a large extent. Even if a gate length A is made small, the drain breakdown strength is not deteriorated.
