Title: Drying of log which utilizes superheated steam
Inventor: IZUMI HYOGO
IPC: F26B9/06
Filed: 1990-01-22
Abstract: PURPOSE:To prevent warp upon sawing and drying pine trees, whose growth is quick, by a method wherein high-pressure steam is poured into a tube, provided in a cap, to intercept a pressure difference between the inside and the outside of the cap while the inside of a pressure vessel is filled with saturated steam and superheated steam is injected against the cutting edges of logs, which are not covered with the cap. CONSTITUTION:Logs are brought to the center of a cap and high-pressure steam is poured into the hopper type cap to inflate a tube and produce a pressure difference between the inside and the outside of the cap. In order to discharge air in a pressure vessel the discharging valve of condensate accumurated in the vessel is opened and high-pressure steam is poured from a boiler into the vessel. Thereafter, the pouring of the high-pressure steam is stopped and when the speed of pressure lowering in the pressure vessel is slowed down, a valve at the lower part of the vessel is closed and the high-pressure steam is poured from the boiler to fill the vessel again with the previous pressure of saturated steam. Superheated steam, having a temperature higher than the temperature of saturated steam, is injected against the cutting edges of the logs, which are at the opposite side of the logs with the cap, and simultaneously the high-pressure saturated steam in the logs is sucked out by an ejector through the sucking circuit of water contained in the logs.

Title: Inspection of pressure contact
Inventor: ITAYA NOBUYUKI
IPC: H01R4/24
Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To provide a method for certainly inspecting pressure contact and its device. SOLUTION: A CCD laser displacement gauge 9 movable in three directions i.e., the vertical direction and two directions perpendicular to each other in a horizontal plane, moves to a pressure contact center 21 to detect a pressure contact height, presence of an electric wire, abnormal pressure contact, and an electric wire appearing margin amount. The former three are detected by measuring the height from a reference position on an upper face of an electric wire sheath in a slot position (the middle position between terminals in the case of two-line terminals), while quality of the electric wire appearing margin amount is decided by detecting presence of the electric wire in a position obtained by subtracting an absolute value of a tolerance from a regular appearing margin position.  Waveform of laser light is sampled during measurement, and the peak point is adopted as a measurement result. Because a light intensity of each pixel is detected in the CCD type, a peak position of the light intensity can be accurately detected even if a surface state is uneven like the electric wire just after pressure contact.

Title: Assessing method of insulation deterioration of electrical apparatus
Inventor: HIROSE SHIYUNICHI
IPC: G01R31/12
Filed: 1978-02-10
Abstract: PURPOSE: To enable insulation deterioration to be assessed by examining the degradation of heat conductivity with time caused by the cavities produced in the insulation layers and dieing of the insulation layers from the temperature rise through current supply to conductor.  
     CONSTITUTION: A conductor 4 and an earth insulation 3 are incorporated by having a certain fixed gap in the iron groove 5 provided to an iron core 1. This earth insulation 3 does not contain any cavities within the insulation layers initially and has specified heat conductivity but upon long-term use, it produces cavities between the insulation layers owing to thermal expansion and shrinkage and mechanical stresses, thus resulting in the decreased heat conductivity. As a result, if the same current is supplied to the conductor 4, the conductor temperature is higher where there are cavities. The degrees of containing the cavities in the insulation layers are grasped by making use of this and the conductor temperatures are measured with time, whereby the insulation deterioration may be assessed.
