Title: Fixing structure of rear parcel trim
Inventor: HIRATA MIEKO
IPC: B60R13/02
Filed: 1985-12-24
Abstract: PURPOSE:To prevent exposure of a body panel structure by forming a fixing seat at a rear parcel shelf panel section in parallel with a flange at the lower edge of a rear pillar trim while inclining toward the central side of cabin. CONSTITUTION:A fixing seat 10 is formed in step in parallel with a flange 7 while inclining toward the central side of cabin at the position for securing a rear parcel trim 2 to the side section of a rear parcel shelf panel 1. Consequently, the fixing flange 11 of the rear parcel trim 2 secured onto the fixing seat 10 will be approximately in parallel with the flange 7. As a result, even upon shrinkage of the rear parcel trim 2 in the lateral direction, the dimension of a gap l0 between the flange 7 and the fixing flange 11 will not vary. Consequently, exposure of the body panel structure due to increase of the gap l0 caused by the lateral shrinkage of the rear parcel trim 2 can be avoided thereby the interior appearance is not damaged.

Title: Semiconductor device, liquid crystal display device formed by using the semiconductor device and their driving method
Inventor: NISHIHATA TOSHIHIKO
IPC: G02F1/1368
Filed: 1994-11-25
Abstract: PURPOSE: To provide a semiconductor device capable of making stable operation with lessened shift of the drain potential by carriers and a liquid crystal display device building the device therein. CONSTITUTION: A part of projecting light generates light carriers (pairs of electrons (-) and holes (+)) in a P type Si substrate 8 when this light infiltrates this P type Si substrate 8. The holes (+) among these carriers advance toward a ground electrode 5 and the electrons (-) advance toward a positively biased source 9, drain 10 and N type semiconductor region 11. Since this N type semiconductor region 11 is larger in area than the drain, the greater part of the electrons do not enter the drain and are absorbed in the N type semiconductor region 11. The shift of the potential of pixel electrodes 18 is thus minimized.

Title: Reclining device
Inventor: MIWA KAZUYA
IPC: A47C1/024
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To easily adjust the angle of a backrest by providing an operation member for separating a slider restricting the rotation of a nut which is locked in a lower bracket from the lower bracket. SOLUTION: An operation handle 71 is rotated by a half degree in a lock state. When a backward load is added to backrest in this lock release state, the seat back is gradually inclined backward since the nut A9 of an upper bracket 1 is screwed onto the lead screw part of a connection shaft 3. When the operation handle 71 is returned to an original state after the backward inclination of backrest, the slider 5 is moved by the elastic force of compression coil spring 35 and a spring 6, the rotation of the nut B4 is restricted and the lock state is obtained. Besides, unless the backward load is added to the backrest in the lock release state, the seat back is rotated by the elastic force of a return spring 12 in a forward inclining direction. In this case, it is gradually rotated since the nut A9 of the upper bracket 1 is screwed onto the lead screw part of the connection shaft 3.

Title: Correction of balance of pneumatic tire for passenger car
Inventor: YAMADA HIDEFUMI
IPC: G01M1/34
Filed: 1986-12-10
Abstract: PURPOSE:To prevent the worsening of high speed uniformity, by scraping rubber off the inner surface of a tire at a position of imbalance which exist in a tire unit. CONSTITUTION:When there is imbalance at a position A of a tire, a radial run out increases at the position A with a higher speed because of a centrifugal force due to the imbalance to enhance radial force variation and tangential force variation in the high-speed uniformity. Rubber is removed from the rear of tread at the position A, namely, the inner surface of the tire to nulify the imbalance. This cancels a balanced force working on the entire tread even when the tire rotates at a high speed to check increase in the radial run-out even in a high speed operation thereby preventing the worsening of the high speed uniformity.

Title: Method for refining high cleanliness dead-soft carbon steel
Inventor: SUETSUGU SEIICHI
IPC: C21C7/068
Filed: 1989-11-14
Abstract: PURPOSE:To reduce oxygen content in a steel and to produce a high cleanliness steel by adding CaO to a slag floating on a molten steel so that the mole ratio of CaO to predicted Al2O3 is regulated to a specific value in the initial stage of killing treatment by means of the addition of Al. CONSTITUTION:In killing treatment by means of the addition of Al succeeding rimming treatment, slag is reformed by adding CaO to the lower side of the slag by means of throwing CaO through a chute onto a molten steel in a vacuum tank in the initial stage of killing treatment in order to prevent the increase in the melting point. The melting point of the slag is reduced by adding CaO so that the mole ratio of CaO to Al2O3 is in the range where CaO/Al2O3 is 0.5 to 2.0 for the above purpose. As a result, oxygen content in the steel after vacuum degassing treatment can be reduced, and a dead-soft carbon steel of high cleanliness can be produced with certainty independently of various variances in respect of vacuum decarburizing treatment.
