Title: Device for feeding powder into gas transportation line
Inventor: KISHIWADA TAKESHI
IPC: B65G53/40
Filed: 1994-02-04
Abstract: PURPOSE:To prevent generation of the leak of the powder such as medicine from a moving part and a flange part by providing a sectional area reducing part of the gas for transportation in a gas transportation line in the vicinity of a powder feeding part to accelerate the gas for transportation flowing in the gas transportation line. CONSTITUTION:Air 5 for transportation to be fed from a blower flows in the piping of the air transportation line in the direction of the arrow. A sectional area reducing part 1 made of rubber to reduce the sectional area in the piping is provided in the piping to provide the negative pressure in the vicinity of a part to feed the powder 6. A opening part 2 to the atmosphere is provided immediately above a feeding part of the powder 6 to allow the atmospheric air flow into the negative pressure part. The powder 6 in a medicine tank 3 is fed to the sectional area reducing part 1 by a medicine feeding blade 4, and transported by the air for transportation. A rubber member of the sectional area reducing part 1 generates fine vibration, and prevents the clogging immediately below the feeding part. The powder 6 is prevented from being leaking by the negative pressure in the vicinity of a powder feeding part, and prevents the pollution of the working environment.

Title: Driving method for photographing lens
Inventor: AMIKURA TAKASHI
IPC: G02B7/09
Filed: 1986-01-23
Abstract: PURPOSE:To prevent a motor from idle running by surely stopping a photographing lens on an infinite end at the time of infinite photographing independently of a state that an infinite switch is fitted to a lens barrel or not. CONSTITUTION:Since the stop of a motor 50 or its driving in the infinite direction can be judged in accordance with ON/OFF of a contact 52 of an infinite switch 51 at the existence of the switch 51, operation is returned to a main program and no decision is processed. When there is no infinite switch 51, whether a photographing lens reaches the infinite end or not is decided. Namely, when a prescribed time has elapsed to make the photographing lens reach from the nearest end to the infinite end after generating an infinite signal and moving the motor in the infinite direction, the motor 50 is stopped. Consequently, the photographing lens can be accurately stopped on the infinite end at the time of infinite photographing independently of the state that the infinite switch is added to the photographing lens or not, so that the motor 50 can be prevented from idle running.

Abstract: PURPOSE:To obtain a hydraulic pressure circuit of an injection molding machine which has prevented drooling by quickening starting of a suck back action, by applying pilot pressure to the rod side chamber of an injection cylinder directly before completion of a charging process. CONSTITUTION:The piston rod 10A of an injection cylinder 10 is moved backward according as resin is charged to a heating cylinder 21 and the rod side chamber 10B of the injection cylinder 10 is replenished with oil through a tank 3. Then a hydraulic motor 11 is turned, the oil of the tank 3 is pressed in the rod side chamber 10B of the injection cylinder 10 through a hydraulic line 19 and pilot pressure is applied to the rod side chamber 10B. With this construction, when a process has shifted to a suck back process by completing a charge process, hydraulic pressure is raised immediately and the piston rod 10A is moved backward by overcoming back pressure. Therefore, drooling is not generated as the back pressure to the applied to an injection cylinder 10C is lowered entirely at the time of completion of charging, in the hydraulic pressure circuit.

IPC: H04N5/238
Filed: 1990-01-22
Abstract: PURPOSE:To prevent hunting without fail when light is turned on/off by providing a light quantity detecting means in addition to a solid-state image pickup element, turning the light on by one output and turning the light off by the other output. CONSTITUTION:The output of a white balance sensor 7 is synthesized by an adder 8, further amplified by an amplifier 9 and supplied to a light control circuit 10 afterwards. The output of a solid-state image pickup element 3 is sampled/held, further AGC amplified and supplied to the light control circuit 10 afterwards. The light control circuit 10 executes control so as to turn light L on based on the output of the above-mentioned amplifier 9 and to turn the light L off based on the output of an AGC circuit 6. Since the light can be controlled to be turned on/off by a histresis loop while using the two light quantity detecting means, the hunting can be prevented without fail differently from the conventional use of the same input signal (the output of AGC).

Abstract: PURPOSE:To obtain a low-cost tubelike film having no connecting part and to further improve a film thickness accuracy by incorporating thermoplastic polyimide resin as a main ingredient and forming a film in a tube state by a melting extruding method. CONSTITUTION:Thermoplastic polyimide resin is contained as a main ingredient, and a film is formed in a tube state by a melting extruding method. Accordingly, the obtained film has no connecting part, and can sufficiently achieve characteristics of the resin of its material. Since melted viscosity is low, it has a low cost, and excellent dimensional accuracy and film thickness accuracy. Since it is sufficiently dried for use, generation of bubbles in the film due to decomposition of the resin and deterioration of thermoplastic fluidity is prevented. The drying is executed by heat treating in a blast circulating type drying oven at 250 deg.C for 24 hours. Thus, excellent heat resistance, radiation resistance and low water absorption rate are provided.
