Title: Device for controlling injection speed of injection molding machine
Inventor: MATSUDA KAZUO
IPC: B29C45/50
Filed: 1987-01-14
Abstract: PURPOSE:To switch over quickly injection speed without a response delay at the changing part of the rising and falling of injection speed by controlling the opening area of an injection nozzle with a specified controller. CONSTITUTION:Injection speed is controlled with a controller 30. The comparison between the actual screw position provided with a screw position detector 21 and the screw position set in a screw position setting device 31 is carried out with a comparator 33. When both positions coincide with each other, a read out signal is sent to an injection speed setting device 32 and is comparated with the actual screw speed detected with a screw speed detector 24, and then the opening degree of a nozzle valve 14 is increased or decreased under control, while feeding a control current to a comparative solenoid 17 until both speeds coincide with each other. Since the injection speed is controlled by changing the opening degree of the nozzle valve 14, the response delay at the changing part in the rising and falling of injection speed becomes small, whereby the injection speed may be quickly dropped or raised.

Title: Driver insertion detector
Inventor: KAMIMURA NOBUYA
IPC: B25B21/00
Filed: 1985-01-16
Abstract: PURPOSE:To prevent the positioning accuracy of a product from dispersing during working by providing a driver insertion detector for the automatic assembly of electrical machinery with the tip bit of a driver and a positioning member to keep a distance between a moving distance detector and the product constant. CONSTITUTION:When a motor mount 7 is advanced by a cylinder 2 under, the guidance of a shaft 8 for its sliding, the whole device goes ahead, and a positioning rod 15 comes into contact with a product 10. The device goes ahead farther and stops after a fixed advance. In this case, a housing 14 is stopped at a position apart by a fixed distance from the product 10 by the positioning rod 15. Consequently, a detector 12 always takes a fixed position to the product 10, and then the tip bit 3 of a driver is brought into contact with a screw 11 under the pressure of a spring 18. In addition, the detector 12 detects a position taken by a disc 13 in a-a' direction and the tip bit having been inserted in the groove of the screw 11. Thus when the tip bit has been inserted into the groove of the screw 11, the screw 11 is rotated by a motor 1.

Title: Low temperature handling device for ic
Inventor: KASE SEIICHI
IPC: H01L21/66
Filed: 1991-01-22
Abstract: PURPOSE:To prevent frost at joint parts between a lower temperature tank of a measuring part and dry chambers and at a movable part of the inside, and prevent dew condensation at IC after concluding the measurement, by providing dry chambers in front and rear of the low temperature tank of the measuring part, and controlling the moisture. CONSTITUTION:A shutter 5 of a before-measurement dry chamber is opened, and an IC 17a is set inside of a before-measurement dry chamber 3. When the inside of the chamber 3 is replaced with nitrogen gas, the shutter 5 is closed, and the inside of the chamber 3 becomes under the condition at an ordinary temperature and a low humidity. On the other hand, nitrogen gas is supplied from a supply part 10 to a low temperature tank of a measurement part, and the low temperature 1 is maintained under the low temperature condition. Under this condition, a shutter 6 is opened, and an IC 17b is set at a measuring position 16 inside of the low temperature tank 1. An IC 17c, of which measurement is concluded, is exhausted into an after-measurement dry chamber 4, but a shutter 7 is opened during the movement. Since the humidity inside of the chamber 4 is less than 0.3%, frost and dew condensation to the surface of the IC is not generated. An IC 17d, of which temperature is returned to the ordinary temperature, is ejected, and a shutter 8 is opened to make the inside of the chamber 4 under the condition at an ordinary temperature and a high humidity, but the inside of the chamber 4 is replaced with nitrogen gas by a supply part 11, and the shutter 8 is closed.

Title: Flyback transformer
Inventor: OKUMURA MASUSAKU
IPC: H01F38/42
Filed: 1989-01-12
Abstract: PURPOSE:To simply improve voltage regulation by mutually shifting resonance frequency by a primary winding part and resonance capacitors. CONSTITUTION:When resonance frequency by a primary winding part PC and resonance capacitors CP1 and CP2 is mutually shifted, a synthetic primary pulse waveform is approximated to a rectangular wave, whereby a peak current Ip flowing through a secondary winding becomes small. That is, voltage regulation is made improved by making the peak current Ip small for making a forward voltage drop Vr due to a diode, a voltage drop Vr due to winding resistance and a voltage drop Vx due to leakage reactance small. Thereby, addition of a separate circuit is not necessary while causing no rise in cost.

Title: Settling tank
Inventor: YASUDA HARUHIKO
IPC: B01D21/06
Filed: 1984-01-18
Abstract: PURPOSE:To obtain concentrated sludge of high concentration by constructing a stirring blade with a net material to prevent generation of bridge without disturbing the flow of the sludge. CONSTITUTION:Filthy water contg. sludge is fed from a feed pipe 3. The direction of the flow is once deflected upward by a feeding port 15, but is straightened thereafter in a flow straightening cylinder 4. The raised water, i.e. the water to be treated flows over an overflow weir 2 and is gathered in a discharging groove 5 and is discharged to the outside of the system from an outlet port 6. On one hand, the sludge is stirred during settling by the stirring blade 13, splitted finely by the net material 14 in the vertical, and horizontal direction and also in the composite direction. Thus, upward passage of water flow is secured, and formation of bridge by the sludge particles with each other is eliminated. Further, the dispersed sludge gathers again and settles as sludge of high concn. The sludge settling to the bottom surface of the settling tank 1 is collected by a sludge collecting blade 12 and is withdrawn to the outside from a discharge pipe 8.

Title: Torque motor
Inventor: KONDO JIRO
IPC: H02K33/18
Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To widen an angle range in which a torque is developed, while not generating torque ripples. SOLUTION: A rotor 41 consists of a core 42 and permanent magnet groups 43 and 44 which consist of 6 flat plate permanent magnets 43a and 44a respectively and bonded and fixed to the outer circumference of the core 42. A stator 45 consists of tooth parts 46 and 47 and an arm part 51. An angle θ3 between the front edge 46a of the tooth part 46 and the front edge 47a of the teeth part 47 is expressed by a formula θ3 =180 deg.-θc /2 with respect to the rotary shaft of the rotor 41. With this constitution, a torque ripple generated in the neighborhood of the front edge 46a of the tooth part 46 and a torque ripple generated in the neighborhood of the front edge 47a of the tooth part 47 cancel each other.  If an angle with which the tooth part 46 surrounds the rotor 41 is denoted by θ1 and an angle with which tooth part 47 surrounds the rotor 41 is denoted by θ2 inequality θ2 >θ1 is satisfied. As a result, torques generated in the later period of rotation can be increased.

Title: Stabilized high voltage power source
Inventor: MAEBA YUKIO
IPC: H02M7/537
Filed: 1983-01-17
Abstract: PURPOSE:To prevent the intermittent oscillation at the no load time and to establish the protecting operation of a stabilized high voltage power source at the load short-circuiting time by accelerating the rising speed of the output voltage of a control circuit, thereby effectively starting an oscillator. CONSTITUTION:When a power source circuit is started, an input level to the reverse phase input terminal of a comparison amplifier AMP of a negative feedback controller 6 becomes low. Since the output of the controller 6 rises in a H level direction, the output voltage of the output point P1 of a controller 2 becomes high. Since a capacitor C5 is provided between the connecting point P2 and a ground voltage point P4, the rising speed of the operating voltage of the connecting point P3 is delayed as compared with the rising speed of the output voltage of the output point P1. As a result, a base current is supplied to the base of an oscillation transistor Tr4, and an oscillator 3 is abruptly oscillated. When the high voltage output is short-circuited, a protecting transistor Tr3 is conducted, and the oscillation of the oscillator 3 is stopped.
