Title: Manufacture of synthetic resin optical element having refractive index dispersion
Inventor: OOTSUKA YASUJI
IPC: B29L11/00
Filed: 1984-07-09
Abstract: PURPOSE:To obtain a vessel wall surface free from local strain and having a uniform equal refractive index dispersion by providing an initial deposited polymer layer on a vessel wall and then depositing and laminating polymer layers different in refraction index in order on the initial polymer layer. CONSTITUTION:The mixture 1 in which a small amount of benzoyl peroxide is added to a mixture composed, for example, of methyl metacrylate and vinyl benzoate with a small amount of benzoyl peroxide added to it is put in the mold 2 having a molding space enclosed by a flat mold surface 2A and a spherical mold surface 2B and is kept still setting with the flat mold surface 2A facing downward. Produced polymer continues to accumulate gradually on the flat mold surface 2B and finally the content in the mold is gelled. This gel is heat-treated, polymerized completely and taken out of the mold 2 to obtain a convex lens where the refraction indexf decreases gradually from the spherical side toward the optical axis.

Title: Clock rate detector
Inventor: KIMURA HIROYUKI
IPC: G01R29/027
Filed: 1980-10-13
Abstract: PURPOSE:To ensure the correct discrimination for the clock rate of a digital signal, by detecting the pulse duration of the digital signal and then detecting the error between the detection output of the pulse duration and the reference voltage. CONSTITUTION:A digital signal received the code modulation on a disk is detected by a pickup 5, and 1 and 0 are decided for this signal by a comparator 11 to reproduce signals. Then the rise and fall points of the reproduced signal are obtained by monostable multivibratiors 12 and 13, and the reversing point of the reproduced signalis detected via an OR gate 14. Then a sawtooth wave circuit consisting of a capacitor 17 for integration etc. is driven to produce a sawtooth wave having the waveheight value proportional to the pulse duration. Only the highest value of the sawtooth wave is peak-held, and the DC voltage proportional to the widest pulse duration is detected. The error between the DC voltage and the reference voltage is amplified by an error amplifier 24 and then added with the start voltage 7 to be applied to a motor driving circuit 2. As a result, an operation is possible with a certain clock rate.

Filed: 1989-06-05
Abstract: PURPOSE:To enhance resolution and to broaden a dynamic range by inserting an optical amplifier between an optical branching means and a photodetector or an optical fiber to be measured and controlling the gain with exciting light in relation to an optical pulse or an excitation current. CONSTITUTION:Light from a light source 2 driven by a pulse generator 1 passes from A to B in the optical branching means 3 to be made incident on the optical fiber to be measured 5 and the reflected light from the optical fiber 5 passes from the B to C in the means 3 to be made incident on the optical amplifier 6. By considering the pulse generating time of the generator 1 and a time when neighboring Fresnel reflected light reaches a semiconductor optical amplifier 6a, a control means 11 controls a driving circuit 6C and the amplifier 6a is controlled with the excitation current. The output from the amplifier 6a is allowed to pass a band pass type optical filter 6b, so that naturally emitted light is removed and only the vicinity of the wavelength of the reflected light is inputted in the photodetector 7 to be converted into an electrical signal. The signal is amplified by an amplifier 8 and the processed result by an averaging circuit 9 is displayed on a display part 10. Thus, the easiness and the accuracy of measurement are improved and a measuring range is enlarged.

Title: Automatic window opening and closing device
Inventor: MATSUMURA KAZUMASA
IPC: B60J1/17
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To automatically open and close a window in a tollhouse by laying the window of a vehicle into opened state when the vehicle approaches to a preset position and the vehicle speed becomes a prescribed speed or less. SOLUTION: The detection of a vehicle is detected by a navigation system 1, and whether it is conformed to the position of a toll road gate or parking garage gate on a map data 12a or not is judged. When the vehicle speed is a prescribed speed or less, and a wiper is not operated, the window is automatically opened. When it is found that a traffic snarl is caused in the vicinity of a tollhouse by VICS information, it is judged that the vehicle speed is lowered because of the traffic snarl, and the automatic opening of the window is not performed. Thus, when the vehicle arrives at a prescribed position such as tollhouse, the window is automatically opened.

Title: Shot blasting method for aluminum die cast product
Inventor: TOMINAGA TSUTOMU
IPC: B24C11/00
Filed: 1987-06-10
Abstract: PURPOSE:To prevent the generation of recesses and blackening by projecting zinc group blast shot having a specific hardness and in which an oxide film is removed from a blast machine to a die cast product at a specific projecting speed at the time of blasting an alternator frame, etc. CONSTITUTION:Using blast shot having a Vickers hardness of Hv=30-39, this blast shot is projected from a blast machine to an aluminum die cast product at a projecting speed of 25-34m/sec. The blast machine can be divided into an air blast type and a centrifugal projecting type. The air blast type continuously projects the shot by means of the jet-out force of air while the centrifugal projecting type carries out projection by utilizing the centrifugal force due to the rotation of an impeller. In both types, the projecting speed can be easily controlled. As for the blast shot, zinc group blast shot is desirable and, in particular, it is desirable to employ shot without oxide on its surface.
