Title: Laser diode driving device
Inventor: HONGO YOSHIYUKI
IPC: H01S5/068
Filed: 1988-03-16
Abstract: PURPOSE:To reduce a circuit size and simplify adjustments by outputting a control voltage which is compensated for a deviation at the set operating temperature in response to the deviation from the set operating temperature. CONSTITUTION:Input data pulses of half mark ratio are applied to an on/off control input of a current switch 6, and laser diode driving current I flowing through a laser diode 2 is cut at a value between the value of zero and the value of driving current that causes rated light output at the operating temperature to be discharged. Set operating temperature is used as reference for the driving current value, and a control voltage needed to electrically conduct the driving current value during this set operating temperature is applied to the current control input from a temperature compensating voltage output means 8. When the operating temperature rises above the set operating temperature, a control voltage compensated for as much as the temperature rise is output from the temperature compensating voltage output 8. When it drops, conversely, the control voltage compensated for as much as the temperature drop is output from the temperature compensating voltage output means 8. As a result of this, since output light is not needed to be monitored, a monitor diode becomes unnecessary, reducing the circuit scale. The adjustments are greatly simplified.

Title: Advanced engine
Inventor: HATTORI SEIZABURO
IPC: F02B57/08
Filed: 1987-03-19
Abstract: PURPOSE:To obtain an engine which runs smoothly and quietly by permitting a driving shaft to be turned by virtue of a rotating movement of pistons and cylinders themselves. CONSTITUTION:The opening end of a cylinder 3 is slided in a close contact with the internal wall of a cylindrical housing 1 so that the cylinder 3 is rotated centering around a driving shaft 2, to which the base 3a thereof is fixed. A fuel inlet 9, an ignition part 8 and an exhaust port 7, which are provided on the internal wall of the housing 1, are set in motion the moment the turning opening-end of the cylinder 3 reaches the position where they are placed, so that a piston 4 is activated. When the piston 4 is pressed in, a guide protrusion 5 provided on the piston 4 is also pressed in the centripetal direction. The guide protrusion 5, which puts its portion projected outwards from a longitudinal groove 11 on the turning cylinder base 3a in an annular cam-groove 6, circulates around the cam groove 6 while the piston 4 is making one reciprocating motion. Therefore, the piston 4 provided with the guide protrusion 5 and the cylinder 3 also turn for 360 deg. within the housing 1 so that the driving shaft 2, to which the cylinder base 3a is fixed, is caused to make one revolution. By fixing many pieces of cylinder base 3a to the driving shaft 2 in directions different from each other, a stable rotational drive can be obtained.

Title: Production of nylon powder
Inventor: YAMAI FUMITO
IPC: C08J3/14
Filed: 1986-03-19
Abstract: PURPOSE:To obtain a nylon powder excellent in flow, etc., by preventing the powder from being aggregated into lumps, by dissolving nylon 6 or 12 in a lower alcohol solvent containing an anhydrous chloride of an alkaline earth metal by heating and slowly cooling this solution. CONSTITUTION:Nylon 6 or 12 is dissolved in a lower alcohol solvent (e.g., methanol or ethanol) containing an anhydrous chloride of an alkaline earth metal (e.g., anhydrous calcium chloride or anhydrous magnesium chloride) by heating. This solution is slowly cooled with stirring at a rate of 3-20 deg.C/hr to obtain the purpose nylon powder. The anhydrous chloride of an alkaline earth metal is added to the lower alcohol in this way, so that the nylon particles deposited and precipitated during slow cooling can be stably dispersed in the solvent, are made nearly spherical and are prevented from being coagulated. The distribution of particle diameters can be easily controlled by the concentration of the anhydrous chloride, the rate of slow cooling, the degree of agitation, etc.

IPC: H01L21/31
Filed: 1987-03-18
Abstract: PURPOSE:To make it possible to form a uniform thin film, and prevent photochemical reaction product from depositing on the light introducing window of a reaction chamber, by moving relatively a light for photochemical reaction on a substrate which is to be subjected to a vapor growth, via a convergent lens system, CONSTITUTION:A lens system 7 is constituted of a concave lens system 7a and a convex lens 7B movable in the direction of an optical axis. A light from a light source 6 is converged on the surface of a substrate 1 which is to be subjected to a vapor growth, via the lens system 7 and light introducing window 5. The conversion position is relatively moved on the substrate 1, via the lens 7B. By the converged light moving relatively, the reaction gas in the vicinity of the substrate 1 surface generates a photochemical reaction, and a thin layer of photochemical reaction product is uniformly formed on the surface of the substrate 1. The luminous flux introduced into the reaction chamber 2 is converged on the substrate 1, and it turns into a dispersion light of low density at the time of penetrating the window 5. Therefore, the generation probability of an active film becomes small, so that photochemical reaction product is prevented from depositing on the light introducing window.

Title: Plural vessel type heat exchange system
Inventor: AJITSUTO KUMAARU MUKAJII
IPC: B01D5/00
Filed: 1984-03-30
Abstract: A gaseous stream comprising nitrogen and solvent vapor istaken from a curing oven (not shown), is passed through preliminary heat exchangers 13 and 23, and enters a first heat exchanger 33 through conduit 30. Remaining vapor is condensed in the heat exchanger 33 by heat exchange with chilled medium entering the heat exchanger from conduit 52 and leaving via conduit 37. The medium then enters a second heat exchanger 43 via conduit 42 where it is chilled by liquid nitrogen supplied via conduit 47, the chilled medium being recycled to the first heat exchanger. The resulting vaporised nitrogen is supplied to form gas curtains at the entrance and/or exit of the oven. This nitrogen leaving the first heat exchanger 33 is used to supply a return stream to the interior of the oven at a rate that substantially matches that at which nitrogen is withdrawn from the oven. This enables a mass balance to be maintained in the oven atmosphere.
