Abstract: PURPOSE:To realize the contact formation in the low temperature environment and to prevent the diffusion region of needless impurity from expanding into a crystalline substrate enabling the contact to be formed in high reliability by a method wherein an upper layer metallic film previously doped with an impurity or under simultaneous doping process is deposition-formed. CONSTITUTION:In order to form a contact between an upper layer semiconductor film 4 and a crystalline substrate 1, after making a through hole 3 in an insulating layer 2 formed on the crystalline substrate 1, the upper layer semiconductor film 4 previously doped with an impurity is deposition-formed on the through hole 3. In other words, the upper layer semiconductor film 4 previously doped with the impurity or under simultaneous doping process is deposition- formed to realize the contact formation in the low temperature environment. Through these procedures, the diffusion region of needless impurity can be prevented from expanding into the crystalline substrate enabling the contact to be formed in high reliability.

IPC: G02B6/12
Filed: 1986-02-17
Abstract: PURPOSE:To provide a lower loss and higher yield by depositing a thin glass film on a silicon substrate on which a heat oxidation film is formed to form an optical waveguide layer and subjecting the optical waveguide layer to polishing at the end faces then to a heat treatment. CONSTITUTION:The heat oxidation film 2 is formed on the silicon substrate 1 and the thin glass film 3 to be made into the optical waveguide layer is formed thereon by a sputtering method. After the thin glass film 3 is deposited and formed, the end faces 4 to act as the incident part and exit part of the optical waveguide are polished and thereafter, the entire part is heat-treated in a prescribed atmosphere. The heat treatment is executed by putting a sample in a quartz tube in which a prescribed gas is allowed to flow and heating the same by a heater from the outside. The low-loss optical waveguide is thus obtd. without the exfoliation of the thin glass film 3.

IPC: B60K23/04
Filed: 1985-02-18
Abstract: PURPOSE:To improve the operability of a vehicle by providing an interlocking member for locking a differential gear while interlocking with a pair of steerable wheels when the steering angle of the steerable wheels is increased and providing a releasing member for releasing the locking by the interlocking member when required. CONSTITUTION:The power of an engine is transmitted to a differential gear through a connecting shaft 33 and rotates a pair of steerable wheels 5 to run a vehicle 2. When a steering handle 23 is rotated in any direction as a speed change lever 1 is in an operational running speed position, a pair of laterally arranged rotary members 18 are integrally rotated through an arm potion 20 and a tie rod 21 to steer the pair of steerable wheels 5.

Title: Fabrication of piezoelectric element and ink jet head
Inventor: MAKITA HIDEYUKI
IPC: B41J2/145
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To suppress fluctuation in the area of inner electrodes of a piezoelectric element by setting the width of an inner electrode narrower at the central part than at the end part when the inner electrodes are screen printed on a green sheet. SOLUTION: When inner electrodes 72, 73 composed of a paste metal material are screen printed on a green sheet 61, the inner electrodes 72, 73 are recessed in the center of the sides 72a, 73a not to be connected with outer electrodes and printing is performed while setting the width L2 at the central part shorter than the width L1 at the end part. When the printed inner electrodes 72, 73 are pressure laminated and fired, they have substantially linear sides 72a, 73a. More specifically, the inner electrodes 72, 73 are substantially rectangular under pressure laminated state. Since fluctuation in the area of inner electrodes of each piezoelectric element is suppressed when a laminated piezoelectric element is split by slit machining, fluctuation of ink drop ejection characteristics is suppressed among channels resulting in a high image quality.

Title: Gate-type shift lever device
Inventor: KOIDE TAMAKI
IPC: F16F7/00
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of unpleasant noises when a shift lever is shifted, by providing a first damper member which projects by a specified amount in the direction opposite to the direction of energization from the side to which the shift lever is energized and a second damper member which is provided at the side opposite to the direction of the projection and whose one side is in contact with a base plate. SOLUTION: If a shift lever 22 shifted to a P range is shifted to a D range, a ball 43 is moved into an engaging hole 24b and the shift lever 22 is stopped. If the shift lever 22 is pressed to a 3 range side in this state, the ball 43 is disengaged from the engaging hole 24b and is engaged with an engaging hole 24b of the 3 range side. On this case, since the shift lever 22 is hit on a first damper member 30 by energizing force of an energizing means 40 with momentum, the first damper member 30 is elastically deformed. A second damper member 32 is arranged opposite to the first damper member 30 of the upper part 24 of a base. Accordingly, the shock of the shift lever 22 is double absorbed by the first and second damper members 30, 32.

IPC: F16F13/10
Filed: 1984-02-21
Abstract: PURPOSE:To reduce a micro-vibration noise produced in a high RPM region of an engine, etc., by providing a means for absorbing high frequency micro-vibration on a partition plate for partitioning a hydraulic chamber in a mount to two subchambers. CONSTITUTION:A hydraulic chamber in a mount is divided into a main hydraulic chamber S1 and a sub-hydraulic chamber S2 by means of a partition plate 11, and a large diameter circular hole 13 is formed in the center of the partition plate 11. The circular hole 13 includes a thin film flexible member such as thin film rubber 21, etc., for blocking the circular hole 13, and a restriction member comprising porous circular plates 31, 32 for restricting a vertical movement of the thin film flexible member. High frequency micro-vibration is absorbed by vertical deformation of the thin film rubber 21, whereby prevents hydraulic pressure inside the main hydraulic chamber S1 from being raised. In addition, since the vertical deformation of the thin film rubber 21 is limited to a prescribed value, hydraulic pressure required for the low-frequency vibration can be assured.
