Title: Lens which can change focal length and irradiation field
Inventor: NAKAGO GENTARO
IPC: G02B3/12
Filed: 1985-06-22
Abstract: PURPOSE:To change the focal length and irradiation field of a lens by filling the inside of an elastic film with fluid and changing the pressure and refractive index of the fluid. CONSTITUTION:A lens-shaped bag is fashioned by using a material having large modulus of elasticity. The curved face of the lens is pushed outward and a concave lens can be fashioned in the central part when an inport tube 2 and an export tube 3 are closed and when rotation ins exerted thereto. This lens does not allow the transmission of light because of scattering when the fluid 6 which scatters the light having a large mol.wt. but the materials which scatter the light having the large mol.wt. gather to the periphery on the outside of the lens and the materials which do not scatter the light having the low mol.wt. gather toward the central part and therefore the optical path can be opened when the rotation is exerted thereto. The focal length and irradiation field can be thereby changed continuously.

Title: Inspection method of system tester
Inventor: TOMONARI NORIO
IPC: G01D18/00
Filed: 1992-04-14
Abstract: PURPOSE:To shorten an inspection time by impressing/fixing a testing false input signal, switching input ranges to/from each other, carrying out an operation on a measurement true value and a delivery threshold value in the respective input ranges, comparing them with an actual measurement value, and judging the quality. CONSTITUTION:A false input signal of prescribed voltage is outputted from a reference voltage generator 3, and when this signal is stabilized, the voltage of the false input signal is measured by means of a digital multimeter (DMM) 4. The voltage is set in the prescribed voltage, and input ranges are set in a prescribed range, so that a measurement value of a system tester 1 can be obtained. Next, an operation on an ideal value (true value) and an operation on a delivery threshold value are carried out, and the accuracy is judged lastly. In order to continue further an inspection by means of the same false input, the input range is switched to the prescribed range, and an inspection procedure is repeated. In this way, an output stabilization waiting time of the testing reference voltage generator 3 is shortened by switching the input ranges to/from each other after the false input signal is fixed, and as a result, an inspection time can be shortened.

Abstract: PURPOSE:To keep the image surface energy constant even if the recording density is switched and to obtain an image of a high quality by providing a collimating beam diameter reducing means and an optical attenuating means on an optical path extending from a collimator lens to a cylindrical lens. CONSTITUTION:On an optical axis of a light emitting part 2 consisting of a light source and a collimator lens, a diaphragm plate 3 being a collimating beam diameter reducing means and a filter 4 being an optical attenuating means are provided and a polygon mirror 6 being an optical deflector is provided so as to be freely rotatable through a cylindrical lens 5. In this state, at the time of high density recording, the light cut-off quantity is decreased by making the inclination quantity of the diaphragm plate 3 small, and also, a light beam is attenuated by placing the filter on the optical path, and at the time of low density recording, the light cut-off quantity is increased by enlarging the inclination quantity of the diaphragm plate 3, and also, the light beam is allowed to pass through by removing the filter 4 from on the optical path. In such a way, even if the recording density is switched, a main scanning speed and an optical output are roughly proportional to each other, and the image surface energy is kept constant.

Title: Manufacturing method of chalcogenic amorphous semiconductor
Inventor: SEGAWA HIDEO
IPC: H01L45/00
Filed: 1978-11-09
Abstract: PURPOSE: To safely manufacture a good semiconductor through a simple process, by hermetically packing raw material elements under a vacuum in a quartz tube ampule, hermetically setting the ampule in a metal tube and vibrating them in a heating furnace to cause the raw material elements to react with one another.  
     CONSTITUTION: Raw materials 1 weighed to a desired composition are put in a thoroughly washed quartz tube ampule 2. The ampule is then removed of air and sealed up. The ampule 2 is put in a metal tube 3. The tube 3 is sealed up with an O-ring 8. The ampule metal tube 3 is heated at a reaction temperature in a heating furnace 4. At that time, a vertical moving mechanism 6 is actuated to vibrate the metal tube 3 at a period of 10 minutes to 1 hour in the furnace 4 through a support 7. The molten raw materials are thus thoroughly mixed to react with one another without taking the quartz tube ampule 2 out of the furnace on the way of the heating and then stirring the materials. This prevents the rupture of the ampule 2 to eliminate dangerousness and provides a good amorphous semiconductor such as As 2 Se 3 .

Title: Ion source
Inventor: HAKAMATA YOSHIMI
IPC: H01L21/265
Filed: 1986-06-16
Abstract: PURPOSE:To maintain an arc discharge to realize stable plasma even in case of introducing compound gas of CF4 or the like, by setting an enough high temperature at a current inflow part of an anode to prevent accumulation of reaction product. CONSTITUTION:An anode projection 3 being electrically conducted to a vessel 1 is installed on an inner side surface of the vessel 1 in the vicinity where a permanent magnet 2 is set up. Electrons emitted from a cathode 4 go toward an inner wall of the vessel 1 or the anode while ionizing gas. And, they take spiral rotation motion by a cusp field 19 produced by the permanent magnet 2, and are converged to flow into a tip part of the projection where the electric field is concentrated. Therefore, the tip of the projection 3 is continuously heated to a high temperature by electron bombardment and Joule heating, thus accumulation of an insulating reaction product can be prevented. With this constitution, stable arc discharge can be secured.

Title: Two-cycle diesel engine
Inventor: MIYAMOTO KANENORI
IPC: F02D9/02
Filed: 1990-05-30
Abstract: PURPOSE:To decrease discharge of harmfull components by providing at an intake passage of air, a control means which decreases scavenging quantity of intake air with respect to a combustion chamber according to decrease of engine load at a no-load operation range including idling operation from low- middle load operation to idling operation. CONSTITUTION:When an engine, during operation is judged by a microcomputer 84 to be in low/middle load operation range at which scavenging quantity is decreased, opening of a control valve 26 (a control means) is determined from a map, and it is decreased according to decrease in engine load. Intake air quantity to a crank chamber 13 is decreased accordingly. When a scavenging port 12 is opened, the scavenging quantity flowing into a combustion chamber 8 from the crank chamber 13 is decreased. As a result, combusted gas remains in the combustion chamber 8. Since a large quantity of components of specific heat is included in the combusted gas, highest temperature of combustion is decreased. Furthermore since the combusted gas is also inactive gas, intake air introduced from the crank chamber 13 is diluted, so that O2 concentration is decreased.
