Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a display device which is capable of being driven by an LSI being small in size and having a low withstand voltage and being of inexpensive and which has small power consumption and with which a display of high quality is possible. SOLUTION: Electric charges pre preserved in the capacitor CD arranged side by side with a counter electrode P constituting the display part of a liquid crystal display device, etc., and the potential VLC of the counter electrode P is displaced every fixed period by utilizing the electric charges. That is, the potential VLC of the counter electrode P is made a high level for a certaing period and the electric charges stored at this time are transferred to the capacitor CD arranged side by side via an inductance L to be stored to make the potential VLC of the electrode a low level. After a lapse of a fixed period, the electric charges stored in the capacitor CD are transferred to the capacitance CLCD had by the counter electrode P via the inductance L to displace the potential VLC of the electrode to the high level again.  After the transferring of the charges, only electric charges equivalent to lost electric charges are supplied from the outside (potential points V1, V2) to make the potential VLC of the electrode a prescribed potential.

Title: Shaft pressing method
Inventor: HISHIDA HIROTOSHI
IPC: B21D26/037
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To prevent buckling or corner wrinkles at a swollen part when the ratio of radius of a corner part of the swollen part and the pipe diameter is small and even a processing condition is severe by varying the increased volume of liquid pressure against the increased volume of the shaft pressing stroke to be low in an early stage of the shaft pressing, high in a middle stage, and low again in a final stage, so that it reaches the final pressure. SOLUTION: At an early stage for pressing a shaft from the processing start till a given point, increased volume of fluid pressure is reduced against increased volume of a stroke of shaft pressing. In a stroke of a shaft pressing early stage where the swollen height of a metallic pipe is within a range of 1/4-3/4 of the swollen part diameter, a liquid pressure P1 is 50-90% of a given fluid pressure. At a middle stage of shaft pressing where the swollen height of the metallic pipe is within a range of 1/2-3/2 of the swollen part 5 diameter, a liquid pressure P2 is 150% or more of the liquid pressure. At the final stage of shaft pressing, a final pressure P3 is used while the liquid pressure is lowered, so that a corner part of the swollen part is enfolded along a corner part of a mold 2.

IPC: G01V3/10
Filed: 1984-03-24
Abstract: PURPOSE:To certainly detect the passage of a metal piece by a simple and small constitution, by detecting the oscillation of an oscillator circuit temporarily stopped by the passage of the metal piece. CONSTITUTION:When a metal piece such as a screw TU passes through an oscillation coil L so as to pierce the same, a part of energy of the coil L is absorbed by the screw TU to be consumed as the loss of an eddy current and the oscillation of an oscillator circuit 1, which has performed high frequency oscillation, is stopped. When this stoppage is detected by a detection circuit 2, a light emitting diode D emits light through a pulse generation circuit 3. By this mechanism, the passage of the metal piece is certainly detected by a simple and small constitution.

Title: Front window open and close device of cabin
Inventor: MIYAZAKI MASAMICHI
IPC: E05F15/16
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To contrive to reduce the size of a drive motor by winding up lockingly around a wind-up drum whose one end is mounted on the lower end of a front window on both sides and whose other end is mounted on the upper part of right and left posts of a cabin and energizing a fixed torque spring in the opening direction of the front window. SOLUTION: A front window 2 is arranged to be slidable from the front surface of a cabin 1 to the ceiling and capable of holding at a cut-off position or an open position so that a fixed torque spring 8 may be laid out on the lower end of the front window on both sides. Furthermore, the front window 2 is arranged to work upward constantly with a compression force of the fixed torque spring 8b, thereby acting effectively with the pull-up motion when the front window 2 is opened. This reduces the operation power required directly before the opening of the front door 2 and hence facilitates the opening of the front door 2. During this operation, the demand for a guide groove to be bored in a bulkhead of a ceiling frame is eliminated so that the strength of a cabin may be maintained.  The fixed torque spring 8b is constantly surrounded with the groove and the front window 2 or it is housed in a wind-up drum 9b, thereby preventing the exposure to the outside and its damage. This construction makes it possible to open the front window 2 easily.
