Title: Method and device for inspecting leakage of container
Inventor: KATAYAMA TOSHIO
IPC: G01M3/34
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To shorten the reaching time to inspection vacuum degree and also prevent the permanent distortion of a container at the same time by suppressing the expanding deformation of the container by covering the container with a chamber and deaerating the inside of the chamber under the condition wherein the inside of the container is opened to atmosphere. SOLUTION: A container A to be inspected, which is mounted on a stationary stage 2, is covered with a chamber 9. At the same time, the surrounding part of an opening B of the container A and the part between the lower edge of the chamber 9 and the surface of the stationary stage 2 is airtightly held by a sealing packing 4. Then, under the condition where the inside of the container 4 is communicated to the atmosphere and opened, the air in the chamber 9 is deaerated. The vacuum degree after the deaeration and the change of the deaeration after the passage of the specified time are detected, and the leakage of the container A is judged. By forming the inner surface of the chamber 9 so as to approach the outer surface of the container, the volume of the space in the chamber at the time of measurement is made small, and the detection is performed in the short time.  Since the detecting environment is made to be negative pressure, the pressure stabilizing time becomes short by the positive-pressure environment. Since the expansion of the container A is constrained at the inner wall of the chamber 9, deformation does not remain.

Filed: 1996-10-02
Abstract: PROBLEM TO BE SOLVED: To arrange many elements straight in line by making the occupying area of each element as small as possible by separating the active layers of two thin film transistors in a self-aligning way by utilizing a pattern for forming source electrodes. SOLUTION: The active layer of a semiconductor layer is divided into CMOS elements by forming opened groove sections 144, 145, and 146. The division is performed in a self-aligning way by utilizing a pattern for forming source electrodes. In this case, the same mask is used for dividing the semiconductor layer and patterning the source electrodes. Therefore, no special mask arrangement nor mask aligning margin are required for dividing the semiconductor layer. In addition, the intervals between the CMOS elements can be narrowed by the margin. Moreover, the intervals between the PTFT and NTFT constituting each CMOS element can be minimized by constituting the PTFT and NTFT of the same semiconductor layer.

Title: Branch distribution measurement of polymer
Inventor: KAMIYA TATSUYUKI
IPC: G01N25/04
Filed: 1989-10-31
Abstract: PURPOSE:To measure a branch distribution with an accuracy comparable to a TREF method with a simple operation and in a short time by performing an isothermal crystalization or the like gradually at an interval exceeding a fixed temperature using a heat analyzer before a melting. CONSTITUTION:A polymer is melted using a heat analyzer at a temperature higher enough than a melting point thereof and then, cooled down to a room temperature. Temperature is lowered performing an isothermal crystalization gradually at an interval exceeding 3 deg.C starting from near the upper limit of the melting point and then, it is raised to melt a crystal. A branch distribution is determined from this behaviour of melting. A heat analyzer herein used is an ordinary differential scan carolimeter or differential heat analyzer. Desirably, it provides a high sensitivity and a stable temperature control. Separation of peak becomes incomplete on a measuring chart of a melting behaviour with the interval under 3 deg.C and hence, a highly accurate determination is impossible.

Title: Electric automobile controller
Inventor: OHORI HARUMI
IPC: B60L7/24
Filed: 1994-11-16
Abstract: PURPOSE: To prevent deterioration of the feeling on a brake pedal which occurs when the transmission of hydraulic pressure on both the drive wheel side and driven wheel side is inhibited in an initial stage of braking. CONSTITUTION: Proportioning valves(P/V) 32r having large gradient characteristics are respectively provided on oil paths from a master cylinder(M/ C) 20 to wheel cylinders(W/C) 26r on the driven wheel side. The opening value of a differential pressure valve 30f on the drive wheel side is set at a value which is nearly equal to that of a differential pressure valve 30r on the driven wheel side. In an initial stage of braking, the braking force on the drive wheel side becomes the regenerative braking force of a motor 14 only and the braking force on the driven wheel side becomes the hydraulic braking force derived from the pressure of the M/C 20 proportionally reduced by the P/V 32r. Since a hydraulic pressure is applied from the W/C 26r in the initial stage of braking, the feeling on a brake pedal 18 is improved.  In addition, since the hydraulic pressure is proportionally reduced by means of the P/V 32r, the braking energy consumption on the driven wheel side does not increase abruptly. Moreover, since the braking force is distributed to the driven wheel side in the initial stage of braking, an excellent braking performance is obtained.

Title: Clock extraction circuit
Inventor: YAMAMOTO MASAKAZU
IPC: H04L7/027
Filed: 1998-10-05
Abstract: PROBLEM TO BE SOLVED: To realize a clock extraction circuit which has higher stability against ambient environment change. SOLUTION: An A/D conversion circuit 4 samples an input pulse with a quadruple clock having a quadruple cycle period of the cycle period of a clock and converts it into a digital value, and a D/A conversion circuit 5 samples an A/D conversion output with the quadruple clock and converts it into an analog value so that the input pulse can be delayed as much as time corresponding to 1/2 cycle period of the clock. The clock is extracted by attenuating this delay output, performing level inversion, adding it to the level of the input pulse, integrating this added output and further comparing it with prescribed threshold level. Because the clock is extracted by a digital circuit without using a resonance circuit in this way, stability is improved more against change of environment such as ambient temperature and humidity.
