Title: Method for extracting medicinal component from melia azadirachta
Inventor: SHIRASAWA KEN
IPC: B01D11/00
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To efficiently extract an effective component from Melia Azadirachta at a low temperature in a short time by subjecting the bark, leaves, blossoms, fruits or root part of the Melia Azadirachta to extraction treatment with a supercritical fluid. SOLUTION: The medicinal properties are extracted from MELIA Azadirachta with a supercritical fluid such as carbon dioxide, ethylene or propane gas. Supercritical carbon dioxide is preferably used in consideration of operability, toxicity and the handling of an extract. Since supercritical carbon dioxide has a density close to that of liquefied carbon dioxide, high solvent power and a high diffusion coefficient, a high extraction rate is attained, and rapid extraction is enabled because of low viscosity. Since supercritical carbon dioxide becomes gas at normal temperature and normal pressure, solvent treatment operation after extraction is unnecessary. Extraction temperature is preferably in the range of 32-80 deg.C and the extraction pressure is preferably in the range of 73-250 kg/m2. Extraction is efficiently carried out in about 16-60 min.  After extraction, an expansion nozzle is released to give normal temperature and normal pressure and the extract can easily be collected.

Title: Automatic answering telephone set
Inventor: SAKAI HAJIME
IPC: H04M1/65
Filed: 1987-02-23
Abstract: PURPOSE:To prevent the electric shock due to a telephone circuit and at the same time to omit a transformer by connecting a specific switch between a ground and a metallic part which is covered by a magnetic tape when the tape is loaded. CONSTITUTION:A switch 6 works in response to the shift of a magnetic head 3 and is turned off when the head 3 moves away from a cassette tape 8 and then turned on when the head 3 moves close to the tape 8 respectively. Then, the switch 6 is connected between a circuit earth and a metallic part which is covered by the tape 8 when this tape 8 is loaded. Thus, the generation of noises can be avoided despite omission of a transformer because said metallic part is connected to the ground when a message is recorded and reproduced. Then, the electric shock due to the voltage of a telephone line or an electric light line can be avoided because the metallic part is separated from the earth when the head 3 is moved away from the tape 8.

IPC: H04Q1/32
Filed: 1990-02-22
Abstract: PURPOSE:To perform the opening/closing of a DC current loop with simple configuration by performing the on/off control of the loop by connecting a photocoupler to the base of a transistor to which the DC current loop is connected. CONSTITUTION:When the supply of a voltage +VCC to the light emitting diode of the photocoupler Pc0 in a loop opening/closing circuit is cut off in a state where a positive voltage is applied to a terminal A and a negative voltage to a terminal B, no light emission of the light emitting diode is performed, thereby, a phototransistor PTr keeps an off state, and the transistor TR0 also keeps the off state, and an open state between the terminals A and B is generated. Also, when the voltage +VCC is supplied to the light emitting diode of the photocoupler Pc0, the light emitting diode emits light, and the phototransistor PTr is turned on, and the transistor TR0 is also turned on, thereby, a current flows from the terminal A to the terminal B via the transistor TR1 and a resistor R0, which closes the DC current loop.

Title: Circuit breaker
Inventor: NISHIZAWA TAKASHI
IPC: H01H73/38
Filed: 1991-03-06
Abstract: PURPOSE:To reduce the operating force for resetting at the time of tripping and facilitate maneuvering by furnishing a supporting plate and a supporting pin to be fitted in a guide groove, which is carved in the direction of energizing a tripping spring for an operation handle. CONSTITUTION:A resetting motion after the tripped state is generated, turns an operation handle 14 from the trip position further in the counter-arrow A direction against the energization force of a tensile spring 15 for toggle. This causes a catch 10 to be pushed by the contacting part 24b of a handle receptacle 24 with the catch 10, which is thus rotated rotund a pin 11 in the counter-arrow C direction, and the free end 10a of the catch 10 is detained with a latch 13 of a tripping device 12. A stationary contacting piece 4 separates from a movable contacting piece 5, and No.1 and No.2 link 7, 8 are left in the bent attitude as they are. A supporting pin 23 of the tensile spring 15 is fitted in a guide groove 24a in the handle receptacle 24 and moves with turning of the handle 14, wherein the locus is in contact with the orbit of a supporting plate 25. Thereby the operating force for resetting at the time of tripping can be reduced, and the maneuvering be facilitated.

Abstract: PURPOSE:To improve the driving stability and utilization efficiency of space, enable direct driving or highly accurate positioning, and improve the energy efficiency by arranging an elastic body coming into contact under pressure with a travel surface and an ultrasonic motor having a vibrator installed in the elastic body in a block member or a rail member. CONSTITUTION:Electric power supply is inputted to an ultrasonic motor 13a arranged in a block member 11 or a rail member 12, and high frequency voltage is impressed upon a piezoelectric element or the like, for example, as a vibrating element. Then, the vibrating element vibrates in a frequency of an ultrasonic wave, and deforms an elastic body 14a, and relatively movable force acts between the block member 11 and the bendable rail member 12, and relative motion can be made between the block member 12 and the rail member by this force. Since the ultrasonic motor 13a can secure acceleration and deceleration large and does not cause electromagnetic noise, a bad influence such as malfunction is not exerted even when it is used in a peripheral equipment such as a computer.

Abstract: PURPOSE: To improve stall margin of a fan by setting an air flow branched at a downstream branch position at a front edge of a rotor blade to be circulated to an upstream branch position at a specific rate to the whole flow of a fan rotor. CONSTITUTION: Fan air is eliminated through a passage 34 at a downstream point of a blade 32, and it is reintroduced through a passage 36 at an upstream point of the passage 34. A front straight wall formed in the passage 34 is cautiously provided having an angle, so a weak axial flow around a case to finally stop components is selectively recirculated. In addition, a strong axial flow is not recirculated to be left in a gas passage, while the weak axial flow is inversely injected into a fan air flow at high speed. Air recirculation of more than twice which may be harmful to component efficiency can thus be avoided. An air flow eliminated from the fan air flow is set to be within 8% of the whole flow flowing to a fan.

Abstract: PURPOSE:To further reduce weight and shorten seek time by inspecting if laser light deflected by way of a triangle prism is vertical to the plane of a glass plate with an auto-collimator, controlling the angle of the triangle prism, and fixing the triangle prism with a carriage section. CONSTITUTION:Laser light 10 deflected by way of a triangle prism 9 is measured by an auto-collimator 1 so as to confirm if the laser light is vertical to the plane of a glass plate 2, which is previously adapted to be vertical to parallel cross light 11.
