Title: Manufacture of thin polydiacetylene film
Inventor: SHIMANOE NORITAKA
IPC: G03F7/025
Filed: 1988-06-10
Abstract: PURPOSE:To produce a thin polydiacetylene film which has less defects and is excellent in mechanical strengths, by transferring a diacetylene compound, which has been formed into an incompletely polymerized spread film by irradiation with ultraviolet light, to a base material and irradiating it with ultraviolet light or an electron beam to complete the polyemerization. CONSTITUTION:A diacetylene compound containing one or more conjugated diacetylene groups in the molecule is spread and irradiated with ultraviolet light in a dose insufficient to complete the polymerization of the diacetylene compound, thereby obtaining an incompletely polymerized spread film. This film is transferred to a base material to form a unimolecular or built-up film, and irradiated with ultraviolet light or an electron beam to complete the polym erization to obtain the aimed film. Examples of the diacetylene compound include 10,12-tricosadiynoic acid and 10,12-pentacosadiynoic acid. The diacetylene compound is dissolved in an organic solvent which can dissolve the diacetylene compound but is incompatible with water, and the solution is used as a spread ing liquid.

Title: Tunnel excavator
Inventor: UEHARA TOSHIAKI
IPC: E21D19/04
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To provide a tunnel excavator which can be propelled without being influenced by the condition of the ground and can be easily moved rearward and prevented from slipping sideways so that devices can be protected when the ground collapses. SOLUTION: A crawler 13, as a propulsion and retreat engine, is provided in a cutter holder 3 provided with cutters 2 for excavating the ground, and supporting plates 15, 16, each of which can move in radial directions of an excavated bore so as to contact the inner surface thereof, are provided in the cutter holder 3. For advancing the holder 3, the plates 15, 16 are brought into contact with the inner surface of the excavated bore and the holder 3 is propelled by the crawler 13, whereupon the holder 3 is advanced, being guided by the plates 15, 16, and hence the holder can be prevented from slipping sideways. For retreating the holder 3, the plates 15, 16 are moved radially inwardly to separate the plates away from the inner surface of the bore and the crawler is driven reversely.  Since the holder 3 is advanced by the crawler 13, there is no need to push the bore by means of gripper so that propulsion can be effected regardless of the condition of the ground. Since the ground is supported by the plates 15, 16, devices in the holder can be protected from the collapse of the ground.

Abstract: PURPOSE:To enable pulverization of wet soil clods and separation from potatoes by providing a soil clod treating device under an outlet of a rotary bucket conveyor. CONSTITUTION:Dug up potatoes (P), stones (S) and soil clods (R) of a harvester are discharged from an outlet 22 of a rotary bucket conveyor 13 onto a soil clod treating device 30. Potatoes (P) having smooth surfaces and stones (S) are hardly bit by helical rolls and smooth rolls mutually rotating in the opposite directions, sent by the helical rolls and transferred to a grader. The soil clods (R) are bit by the helical rolls and smooth rolls, pulverized into fine particles and dropped onto the ground surface. The stones are bit by the helical rolls and smooth rolls depending on the shape thereof. Although a hydraulic motor for driving the helical rolls and smooth rolls is overloaded, the hydraulic motor is reversely rotated for a prescribed time by a control circuit to discharge the bitten stones. The soil clods are pulverized and only the potatoes (P) and stones (S) are fed to the first grading rolls 18 of the grader to separate the stones. Thereby, only the potatoes reach the top of the final grading conveyor.

Title: Temperature control circuit of semiconductor laser
Inventor: YASUJIMA HIROMI
IPC: H01S5/042
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To enable the temperature of a semiconductor laser to be maintained at a specific value even if the environmental temperature fluctuation is notable by a method wherein the output of the second sensor is added to the inside of a feedback loop as a feed forward signal so as to make the temperature of the semiconductor laser approach to a target temperature. SOLUTION: The temperature of a semiconductor laser 4 detected by a thermistor 5 is compared with the target temperature 1 by a comparator 2 so as to drive a Peltier element 3. At this time, the feedback control is repeated according to the temperature detected by the thermistor 5 to be operated for making the temperature of the thermistor 5 coincide with the target temperature 1. Furthermore, the environmental temperature is detected by an environmental temperature sensor 6 to compare the difference between the target temperature 1 and the environmental temperature by another comparator 7 for adding the difference to an adder 8 thereby enabling the fluctuation in the environmental temperature to be cancelled.  Accordingly, even if the environmental temperature is notably fluctuated, the target temperature 1 can be made coincide with the thermistor temperature thereby enabling the precise temperature control to be made feasible.
