Title: Shift controller of automatic transmission for vehicle
Inventor: SEKIGUCHI HIDEKI
IPC: F16H61/16
Filed: 1990-02-23
Abstract: PURPOSE:To secure the extent of stability at time of running downhill by controlling the shift speed of an automatic transmission so as to be maintained on the basis of a deviation between rotational frequency of an input shaft of the transmission and that of an internal combustion engine at a time when a decelerated driving state is judged. CONSTITUTION:When a decelerated driving state is judged on the basis of throttle valve opening by a throttle valve opening detecting means A, by a decelerated driving state judging means D, a shift maintaining means E maintains the shift speed of an automatic transmission on the basis of a deviation between rotational frequency of an input shaft of the transmission and that of an internal combustion engine. Accordingly, even if a driver separates his foot from an accelerator and fully closes a throttle valve, such a fear that shift-up operation might be busily performed in conformity with a shift line is prevented, thus operability is improved and simultaneously safety at time of running downhill is also secured.

Title: Manufacture of printed wiring board
Inventor: HORII YOSHIAKI
IPC: H05K3/42
Filed: 1992-03-02
Abstract: PURPOSE:To reduce breaking of discontinuity and defects by forming a conductive resin layer on a photosensitive resin film to prevent static electricity and hence deposition of foreign objects, in view of the fact that the photosensitive resin layer easily accumulates static electricity since it has no conductivity, and thus foreign objects deposit on portions of the photosensitive resin layer and these portions are not exposed to light at the time of exposure, which causes discontinuity of the wiring and defects. CONSTITUTION:A copper-clad insulating substrate 1 is coated with a positive photosensitive resin film 8 by electrodeposition, and then the insulating substrate 1 is coated with a conductive resin and dried, thereby obtaining a conductive resin layer 9.

Title: Valve system in internal combustion engine
Inventor: YANAGI NORIO
IPC: F01L1/18
Filed: 1989-02-24
Abstract: PURPOSE:To improve the rigidity of a locker arm and the durability of a spacer body by providing the spacer body which is constructed so that it may be changed over to an engaged condition or an disengaged condition between a main contact portion and a sub contact portion. CONSTITUTION:When a spacer body 26 is engaged between a main contact portion 22 and a sub contact portion 23, the clearance between both contact portions 22, 23 is decreased by the spacer body 26, and the oscillating movement of a sub locker arm 20 brought into touch with a cam 16 for high-speed is transmitted to a main locker arm 19 through the spacer body 26. Since the main locker arm 19 rotates oscillating through the cam 16 for high-speed, an intake valve 4 is opened and closed by the valve timing or valve lift conforming to a high-speed rotational range. In this case, the spacer body 26 is placed between both the contact portions 22, 23, so valve opening force does not work upon the spacer body 26 as bending moment and shearing load at the same time, but as simple compressive force.

Filed: 1990-02-27
Abstract: PURPOSE:To make it possible to perform measurement characterized by high S/N and high accuracy by using a sample pan comprising a rotary parabolic surface wherein the inner wall is constituted of a light reflecting material. CONSTITUTION:In a sample pan 1, a recess part is provided at the approximately central part of a metal stage so that the wall surface forms a rotary parabolic surface 2. The parabolic surface 2 is finished so as to have the mirror surface, and gold is plated. Therefore, light is excellently reflected from the surface 2. Light 20 from a light source is made to be the monochromatic parallel light through a spectroscopic system using a monochromator or an interference filter. The light 20 is reflected from a mirror 13 and inputted into the sample pan 1 in parallel with the rotary axis of the parabolic surface 2. Then, the light which is inputted in the sample pan 1 directly impinges a sample 5. Or the light is reflected from the parabolic surface 2 and directed to a focal point F. Then, the light impinges the sample 5. When the sample 5 is illuminated, light 21 emitted from the sample 5 is inputted into an integrating sphere 11 directly or after the reflection from the parabolic surface 2. The light is reflected from the inner wall of the integrating sphere 11 and finally inputted into a detector 12. Thus the sample 5 is analyzed.
