Filed: 1990-07-16
Abstract: PURPOSE:To gradually decelerate the driving speed of a motor and to stably stop it by so controlling the frequency of a voltage to be applied to a piezoelectric element that a deviation of a vibrator from a resonance frequency is gradually increased as a deviation between the driving position detected by position detecting means and a target driving position is reduced. CONSTITUTION:A target speed and a target position for stopping a motor are set by target value setting means 7. Fuzzy control means 9 varies the output frequency of a servo amplifier 5 so as to reduce a speed deviation if a speed deviation from the target speed is large, and always operates to control to the target speed. When the positional deviation reaches a set value, the target speed is stepwisely set to a smaller value by control means 11 to stop the motor. Thus, the operation at the time of stopping can be controlled stably and accurately at the stopping position.

Title: Constituent of pedestal periphery in gas channel in chemical vapor deposition chamber
Inventor: ZHAO JUN
IPC: H01L21/205
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To increase the average number of wafers treated from chamber cleaning to the next cleaning, by improving the performance of a chamber for depositing titanium nitride. SOLUTION: The tendency that gas for deposition forms excessive product in a part of a pedestal 140 which stretches over the periphery of a substrate 142 to be treated is reduced. This constituent contains a peripheral ring 146 which is thermally insulated from the pedestal 140 and the substrate 142 to be treated. As the result of thermal insulation, the temperature decrease of the peripheral ring causes the decrease of thin film deposition rate on the surface of the peripheral ring. Thereby the average number of wafers between cleaning cycles of a treating chamber is increased. The peripheral ring 146 contains a centering boss to assist the centering when the substrate is made to descend down to the surface of the pedestal.

Title: Production of laminated lens
Inventor: ADACHI EINOSUKE
IPC: G02B3/08
Filed: 1987-07-30
Abstract: PURPOSE:To make mass production by injecting a UV curable resin into a lens mold, covering the mold with a glass plate, projecting UV rays through the glass plate to the UV curable resin packed between the glass plate and the lens mold to cure the resin and parting the laminated lens formed on the glass plate from the lens mold. CONSTITUTION:The UV curable resin 1A is injected into the lens mold 4 having the shape of a lens face and is covered with the glass plate 6. The UV rays are projected through the glass plate 6 to the UV curable resin 1A packed between the glass plate 6 and the lens mold 4 to cure the resin; thereafter, the laminated lens is parted from the lens mold 4, by which the laminated lens 7 consisting of the glass plate 6 and the resin 1A is obtd. Since the lens 7 is directly formed on one face of the glass plate 6, there is no need for previous grinding of a plastic lens and since this lens is formed not by sticking of the lens 7 and the glass plate 6, the number of parts is smaller and the stage is shorter. Intrusion of air bubbles and foreign matter into the lens is, therefore, obviated and the productivity is greatly improved.

IPC: H04R1/28
Filed: 1992-07-16
Abstract: PURPOSE:To reproduce an ultralow frequency sound over a wide band by providing a peak to each sound radiating from each duct at a different frequency and synthesizing them. CONSTITUTION:The inside of a cabinet main body 1 is parted into two parts by a partition plate 2, and a speaker unit 3 is mounted on the partition plate 2. Furthermore, an enclosed sub cabinet 4 is formed to a rear side of the speaker unit 3 through the partitioning and a main cabinet 5 is formed to a front side of the speaker unit 3. The main cabinet is separated by a partition plate 8 so as to form two air chambers 5a, 5b having ducts 6, 7 respectively. Since the air chamber 5a(5b) has the duct 6(7) respectively, the chambers act like a Helmholtz resonator. The resonance frequency of the air chambers 5a, 5b is made different by differentiating the length or the cross sectional shape of the ducts 6, 7.

Title: Focal plane shutter for camera
Inventor: TAKAHASHI SHIGEMI
IPC: G03B9/36
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To provide a focal plane shutter for a camera, constituted such that a 1st blade group and a 2nd blade group are prevented from interfering with each other at a position near the pivotally attached parts of respective arms in terms of actuation. SOLUTION: A space between a shutter base plate 1 and an auxiliary base plate 46 are partitioned by an intermediate plate 36, so as to form the blade chamber of the 1st blade group and that of the 2nd blade group. Then, two arms of the 1st blade group are pivotally attached to shaft 1r and 1s, and two arms of the 2nd blade group are pivotally attached to shafts 1t and 1u. Additionally, a well-known backlash gathering spring is laid between the arms, attached pivotally to the shaft 1s and 1u. Conventionally, the actuation plane area of the arm part of the backlash gathering spring is not partitioned by the intermediate plate. However, extended parts 36g, 36h and 36i are formed at the plate 36 and prevented from being brought into contact with the coil part of the backlash gathering spring, so as to partition the area.  Thus, the blade groups are prevented from interfering with each other in that area.
