Inventor: SEKIYA YOSHIKI
IPC: F16F15/30
Filed: 1991-12-04
Abstract: PURPOSE:To ensure stable rotation by disengaging a clutch when an engine cooling water temperature exceeds a given value, running a motor, engaging the clutch and stopping a motor during a starting and cold down, engaging the clutch when a battery voltage is low, and generating a power with the aid of a motor. CONSTITUTION:When a cooling water temperature is low during the starting of an engine, an electromagnetic clutch 16 is engaged and a flywheel 17 is connected to an engine rotary shaft 11 through a speed increase gear 15. Thereby, stable rotation is ensured togetherwith a smooth starting during cold down and idle running. When the number of revolutions of an engine exceeds a set value during warming up, the electromagnetic clutch 16 is disengaged and a flywheel 17 is separated. Thereby, an inertial mass is reduced and high acceleration response and acceleration performance are ensured. In this case, a motor 18 is run and the flywheel 17 is rotated at the given number of revolutions. When a battery voltage is reduced, the electromagnetic clutch 16 is engaged and a power is generated with the aid of the motor 18 caused to run at a high speed by means of the speed increase gear 15. Thus, power generating efficiency is improved and charge can take place in a short time.

Title: Method for manufacturing optical disc substrate
Inventor: HATASAWA TAKENOBU
IPC: B29L17/00
Filed: 1987-12-18
Abstract: PURPOSE:To obtain an optical disc substrate with properties such that the change of a birefringence caused by the heat given during drying or metal thin film adhering in following process may never happen and the birefringence at the time when it is finished is small, furthermore, the distribution in its radial direction is uniform, by anealing the substrate having a distribution of the birefringence of specified pattern in its radial direction. CONSTITUTION:A substrate having latently a circumferential tensile stress which becomes strong as it goes to the inner peripheral surface of the substrate is formed through a formation of a substrate having a distribution of birefringence in specified pattern in its radial direction in order that the birefringence is largest in the inner peripheral portion of the substrate and it becomes small an it goes to the outer peripheral portion. Following this, the substrate is given with as anealing and it is changed in its shape through the heating contraction in the radial direction. The circumferential tensile stress moving towards to the inner peripheral portion of the substrate is offset with the circumferentially directional compression stress produced by the heating contraction moving towards the inner peripheral portion of the substrate. As a result, any stress resides no longer in the region of the inner peripheral portion and the birefringence in the vicinity of the inner peripheral portion becomes considerably small, so that the birefringence is very small ranging over the whole inner surface of the substrate surface and the distribution in the radial direction becomes uniform.

Title: Flow type apparatus for measuring absorbance
Inventor: SUZUKI KOJI
IPC: G01N21/03
Filed: 1991-11-11
Abstract: PURPOSE:To converge efficiently a reflected light from a sample layer of a wide area and thereby to measure the absorbance of a liquid sample with high sensitivity by providing a Cassegrain optical system so that the focus be formed in the same region as a columnar member on the surface of which a reflecting surface is formed and which is disposed vertically. CONSTITUTION:A sample supplied from a sample discharge port is distributed in the circumferential direction uniformly by a conical part 1a and flows down, in the form of a layer having a ring-shaped section, on the surface of a columnar member 1. When a light is made to enter in this state, the light converged by a Cassegrain optical system 3 irradiates the whole circumferential surface of the columnar member 1 and is absorbed by a sample layer S formed on this surface, and then it is reflected in the direction of the whole circumference by a reflecting layer 2 and passes the sample layer S again. This reflected light is converged by a concave mirror 6 of a Cassegrain optical system 4, converged again by a semispherical mirror 8 and made to enter a light-detecting means from an emission port 6a. According to this constitution, the reflected light from the sample layer S formed on the circumferential surface of the columnar member 1 can be led to the light-detecting means efficiently and thus measurement of the absorbance with high sensitivity is enabled.

Title: Conveying device
Inventor: SUSA HARUYUKI
IPC: B65G43/08
Filed: 1992-11-06
Abstract: PURPOSE:To enhance the availability factor of a weighing device by determining the driving/stopping timing of a conveying means in response to the moving speed of articles on the conveying means; in other words, by quickening the timing from the detection of article up to the driving or stopping when the moving speed of articles is fast, while by delaying the timing when the moving speed is slow. CONSTITUTION:When a hopper sensor 12 detects that the inside of a pool hopper 7 is empty for sending out an ON signal, an exciter 5 is derived. By the excitation, the articles to be weighed flow on a trough 6, and is detected by an image sensor 10, so that the number of the articles is counted, and also the moving speed of the articles is measured. When the moving speed of the articles is relatively slow, the delay time from the point of time when the last article to be weighed has been detected up to the time when the excitation of the trough 6 is stopped is lengthened so that the articles to be measured are securely dropped inside the pool hopper 7; while when the moving speed is relatively fast, the delay time is set to be shorter, so that surplus articles succeeding the last article to be weighed can be prevented from being dropped inside the pool hopper 7.
