Title: Steel corded conveyor belt
Inventor: OKAMOTO HIROSHI
IPC: D07B1/06
Filed: 1978-12-29
Abstract: PURPOSE: To improve the breakproof and life expectancy of a conveyor belt, by keeping the twist factor of center strand with a magnification of 1W1.8 against the twist factor of the cord and using the same size of wires as side strands.  
     CONSTITUTION: For a 7×7 steel cord 1, the twist factor of its center strand 3 is about 1W1.8 times that of the cord 1, so that the center strand 3 alone is not broken prior to the cord break. Since the same size of wires used as side strands 4 reduces the effect of contact among the side strands 4 and accordingly reduces the internal wear of the cord, the resistance to bending fatigue is improved. So a conveyor belt 2 reinforced with steel cords of this construction has its strength and life expectancy greatly improved under any vulcanizing conditions as compared with those of conventional belts.

Title: Waterproof optical fiber tube unit
Inventor: KUNIFUMI TOSHINAO
IPC: G02B6/44
Filed: 1985-07-25
Abstract: PURPOSE:To improve the connecting work efficiency and producibility by sticking a water absorbing material to the inner wall of a tube and interposing a waterproof resin or a water absorbing material between optical fiber tapes in the tube. CONSTITUTION:A waterproof resin 2 is filled into the gaps between optical fiber tapes 1a, 1b, 1c, 1d and a water absorbing nonwoven fabric 5 is stuck to the inner wall of a tube of polyethylene 4 lined with an Al tape 3. Since the fabric 5 is easily stuck to the Al tape 3, a tube unit having a water absorbing nonwoven fabric stuck to the inner wall can be easily formed. A waterproof resin having low viscosity selected among conventional waterproof resins for a waterproof cable such as petroleum resins and jellylike compounds is suitable for use as the waterproof resin 2. The water absorbing nonwoven fabric 5 is made of a water absorbing cellulosic material. In the dry state, the fabric 5 is fibrous and nonsticky, but when the fabric 5 absorbs water, it swells and fills the space in the tube.

Title: Device and method for operating simulation
Inventor: SHIMIZU KAZUMA
IPC: G05B19/4097
Filed: 1992-06-22
Abstract: PURPOSE:To facilitate an operation when a CAD diagram is used by defining the angle of rotation for rotation or interference movement for translation and calculating an operation amount. CONSTITUTION:In an operating method deciding step 3, a defined operating method is decided. In an interference translation operation definition step 10, an interference translation operating method is defined and in an interference translation operation calculation step 11, an interference translation operation amount is calculated. In a display and registration step 16 for an operation result, the arrangement of the object shape to be operated is altered by the calculated operation quantity and displayed again. Thus, the operation is carried on until the object figure comes into contact with an interference object figure. The angle of rotation for the rotation or the interference operation for the translation is defined, and then the operation amount is calculated to enable the operation. Consequently, the operation is facilitated when the CAD figure is used.

Title: Fuel injection pump
Inventor: NOZAKI MASAYA
IPC: F02M41/12
Filed: 1985-07-25
Abstract: PURPOSE:To improve injection performance during high speed revolution by using, in addition to a first pressurizing chamber, a second pressurizing chamber and by introducing fuel pressurized in the second pressurizing chamber during the stroke of pressurized feed of fuel in the first pressurizing chamber into a separately formed cylinder chamber. CONSTITUTION:A barrel 6 is of a two-stepped shape consisting of a smaller diameter section 61 and a greater diameter section 62. A first pressurizing chamber 9 is formed by the smaller diameter section 61 and a plunger 7 tip. A second pressurizing chamber 10 is formed by the greater diameter section 62 and the tip of the base section of the plunger 7. While the first pressurizing chamber 9 is in pressure-feed stroke, fuel oil in the second pressurizing chamber 10 is pressurized and stored in a cylinder chamber 141. During the suction stroke of the first pressurizing chamber 9, pressurized fuel in the cylinder chamber 141 is introduced into the first pressurizing chamber 9, while fuel in a pump chamber 4 is introduced into the second pressurizing chamber 10. As a result, adequate fuel can be introduced into pressurizing chambers even when the plunger is driven at high revolutions.

Title: Image forming device
Inventor: INUZUKA TSUNEKI
IPC: G03G15/00
Filed: 1979-12-15
Abstract: PURPOSE: To control the roller pressing force of an image forming device with simple constitution and form a good quality image by detecting pressure by the use of a piezoelectric high polymer composite material for electro-mechanical conversion and controlling the pressure-contact force between a revolving roller and pressure roller.  
     CONSTITUTION: When a transistor Q2 is turned off by a CPU at the starting of copying, the reference voltage applied to an operational amplifier Q1 is the reference voltage corresponding to the required pressing forces of a revolving roller 1 and a pressure roller 2. On the other hand, the voltage corresponding to the detected pressure from a piezoelectric high polymer composite material 7 for electro-mechanical conversion forming part of the pressurizing mechanism is applied to this amplifier Q1 and the pressurizing mechanism is controlled by way of a DC motor 9, whereby the pressing forces between the rollers 1 and 2 is controlled to a required value. When the reference voltage of the amplifier Q1 lowers at the end of copying, the motor 9 turns until it is stopped by the similar operational amplifier Q4 and transistor Q5, thus the rollers 1, 2 are so controlled that no unnecessary pressing forces are generated between them while not in use. Hence, the roller pressing forces of the image former are controlled with the simple constitution and good quality image formation is accomplished.
