Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To eliminate light leakage originated from spacer beads in a horizontal electric field mode normally closed type and to improve a contrast ratio by controlling optical leak centering a spacer to become a quadripartite form. SOLUTION: In this normally closed type liquid crystal display, an active matrix type liquid crystal display device wherein it adopts the horizontal electric field mode and a pre-tilt angle between an alignment control film and liquid crystal is set to 4 degrees or less, optical leak centering a spacer is controlled so as to become a quadripartite form 41.

Inventor: SAKAMOTO HIDEKI
IPC: H04N7/173
Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To attain write processing and read processing of moving image data by using an idle time slot in the same period or another spare time slot formed because the processing has been unable to be implemented so as to retry the processing. SOLUTION: When moving image data to be read are not written yet, the data are given to a read processing queue 33 and the time slot is used for a spare time slot. In the case that the spare time slot is formed or an idle time slot is used from he beginning, a write queue 32 discriminates that the moving image reaches a control means 31 and whether or not there is any executionable processing. When the corresponding processing is not in existence, the moving image data are written in a storage device 30, and when there is any executionable processing, the moving image data are read, the time slot is finished. When the corresponding processing is not in existence, a proper time is awaited to take timing and then the time slot is finished.

Title: Heat-treatment method and treatment method
Inventor: KUREBAYASHI TAKESHI
IPC: H01L21/22
Filed: 1991-01-18
Abstract: PURPOSE:To enhance the uniformity of a sheet resistance inside the face of an object to be treated and between faces of objects to be treated when, e.g. phosphorus is thermally diffused to the objects to be treated such as semiconductor wafers or the like. CONSTITUTION:Semiconductor wafers W are introduced into a reaction container 1 which has been heated to a prescribed temperature; then, a carrier gas and a treatment gas which contains a doping component are supplied to the semiconductor wafers W via an injector 8. At this treatment, the flow rate of the carrier gas is changed. For example, the flow rate of nitrogen gas as the carrier gas is first reduced. After a prescribed time has elapsed, the flow rate is increased. Thereby, the lack of uniformity of a sheet resistance inside the face of each wafer and between faces of wafers when the flow rate has been set individually is, e.g. offset, and the uniformity of the sheet resistance is enhanced. Even when the supply position of the treatment gas is changed inside the process face of the object to be treated instead of changing the flow rate of the carrier gas, the same effect can be obtained.

Title: Lens barrel
Inventor: TAMURA MASAHISA
IPC: G02B7/04
Filed: 1990-01-30
Abstract: PURPOSE:To prevent a cam follower from coming out and to improve the operability by inserting the cam follower into a fixed cylinder from outside, inserting a screw into the center hole of the cam follower, and engaging the fixed cylinder with a cam cylinder by utilizing the expansion of the cam follower. CONSTITUTION:Since the cam cylinder 2 receives the torque from a driving member and a cam groove 2b and a surface 2b of the cam follower 3 engage each other, the cam cylinder moves in the direction of the optical axis while rotating along the cam groove 2b by receiving the torque. A surface 1c of a fitting part A deforms and the cam follower 3 does not rotate about the fixed cylinder 1. A fitting part B prevents the cam follower 3 from coming out of the fixed cylinder 1 and the screw 4 which has a larger external diameter than the hole diameter of the hole 3c of the center part of the cam follower is screwed in the hole 3c; and the surface 3a of the cam follower 3 begins to swell outward as the screw is inserted and is pressed and fixed to the surface 1b of the fixed cylinder 1. Consequently, the cam follower becomes hard to come out and the operability is improved.

Abstract: PROBLEM TO BE SOLVED: To enable power control of multipulse even under a high-speed transfer rate by controlling a laser power, which is subjected to sample-and-hold based on an output control pulse, so that the laser power runs up to a prescribed value. SOLUTION: LD control signals LDC1, LDC2, LDC3 perform the operation control of a first, second and third current sources 71, 72, 73 respectively. Each LD control signal LDC is set at a prescribed value by a recording output control circuit, while the current of the first to the third current sources 71, 72, 73 is each set at a specific value. A semiconductor laser driving circuit 70, in accordance with LD recording signals LD Data 1-LD Data 3, makes a semiconductor laser 3 generate multipulse emission. Thus, each output can be stably controlled for the peak power and bias power 1, 2 of the multipulse, even during the recording operation in which the laser power fluctuates by the effect of return light from the optical disk.
