Title: Control equipment of measured back pressure of motor driven injection molding machine
Inventor: SAKAUCHI SABURO
IPC: B29C45/76
Filed: 1986-05-13
Abstract: PURPOSE:To perform high and uniform kneading of resin, by a method wherein reaction force to be generated according to a rotation of a screw is detected by a load cell and driving force of the screw in an axial direction is controlled on this detected value. CONSTITUTION:At the time of measuring, a screw 11 is moved backward by reaction force of resin stored at the tip of a barrel 13 and an electric motor 22 for a movement of the screw in an axial direction. Resultant force of these two backward movement force are detected through a load cell. A detected value is applied to a comparator 33 after being divided by cross-sectional area of the inside diameter of the barrel 13 and converted into a pressure unit by an arithmetic unit 32 after being amplified by an amplifier 31. The value applied to the comparator is compared with that preset in the comparator and when the deviation value is generated, a control signal is amplified by an amplifier 35 and sent to the electric motor 22 through a driver 36. Output of the electric motor 22 is controlled to a value suitable for the deviation value. Then uniform and high kneading of resin is always possible.

Title: Nozzle clogging detection for ink jet recorder
Inventor: MURAI TOSHIHARU
IPC: B41J2/125
Filed: 1985-05-23
Abstract: PURPOSE:To utilize 'wait' time to detect nozzle clogging with the help of an ink droplet out phase detection means by charging ink droplets on a charging signal having a longer time width than the (t) cycle of vibration applied to ink and detecting their existence with a detection electrode. CONSTITUTION:A pressurized ink is injected through a nozzle 3 and at the same time, a vibration of fixd cycle is applied to the ink. Then it is charged by a charging electrode 7 the moment when it is atomized into droplets. At that time, the time width of the charging signal is made longer than a single cycle of vibration applied to ink by an electric distortion vibrator 4. That is, the m-1 pieces of ink droplets are charged by making the time width of the charging signal on the charging electrode 7m times as much as a single cycle of an exciting signal (a) by the electric distortion vibrator 4. The ink droplets collide with a detection electrode 11 after being deflected, releasing the electric charge to be transmitted by a detection circuit 12. If no detection is made by the detection electrode 11, it is judged as clogging. Thus it is possible to utilize the conventional ink droplet cut phase detection means as such and detect any clogging by utilizing 'wait' time until a stable state after the making of a power supply.

Filed: 1994-05-24
Abstract: PURPOSE:To make it possible to freely change the coefft. of expansion of a casting mold by compounding a specific ratio of tungsten metallic powder with a binder. CONSTITUTION:The tungsten metallic powder is compounded at 5 to 40wt.% of the binder with the binder of the molding material for a titanium alloy consisting of the binder, such as alumina cement or zirconia sol, and aggregate, such as zirconium oxide or magnesium oxide as basic components.

Title: Engine driving type heat pump air conditioner
Inventor: TANITAKA TOSHIHIRO
IPC: F25B43/00
Filed: 1990-04-27
Abstract: PURPOSE:To prevent a lack of refrigerant at the beginning of starting an operation and further to prevent liquid refrigerant from entering a compressor by a method wherein a plurality of accumulators are connected to a refrigerant circulation circuit and an accumulator placed near a suction side of the compressor in respect to the refrigerant circulating direction is disposed in an engine room and the remaining accumulators are disposed outside the engine room. CONSTITUTION:An accumulator 15b disposed outside an engine room 30 holds liquid refrigerant under an environment of low temperature and the accumulator may act as an entire refrigerant reservoir for a refrigerant. Keeping the refrigerant under its liquid condition does not produce any lack of refrigerant. An accumulator 15a disposed within the engine room 30 is disposed under a higher temperature environment than that of other locations. Due to this fact, the refrigerant within the accumulator 15a is gasified. That is, the liquid refrigerant fed from the accumulator 15b is gasified, thereby the refrigerant may not flow into the compressor 2a at the beginning of starting operation while being kept in its liquid state.

Title: Indirect type hydraulic elevator
Inventor: NISHIOKA KENICHI
IPC: B66B5/02
Filed: 1995-05-09
Abstract: PURPOSE: To easily judge propriety of upward thrust allowance by storing the action of a plunger thrust-out preventing switch when the plunger thrust-out preventing switch near the uppermost floor of an elevator shaft is put in action by a cam at the tip of a plunger due to the increase of the thrust-out quantity of the plunger caused by the elongation of a main rope. CONSTITUTION: When a main rope is elongated with the lapse of time and upward thrust allowance becomes small, a plunger thrust-out preventing switch is put in action to open an electric switch 3b. A relay Y drops out (is demagnetized), a b-contact 11 is turned on, and a relay Z picks up (is magnetized), so that an a-contact 12 is turned on to self-hold. Pickup is continued until a push button 13 for resetting the relay Z is pushed. When the relay Y drops out, an a-contact 14 is turned off, so that a relay U for making an elevator ascend drops out, and the ascent of the elevator is stopped. Adjustment timing of upward thrust allowance can be known only by confirming the pickup of the relay Z.
