Title: Noise reducing device for step motor
Inventor: NISHIZAWA HIROSHI
IPC: G11B21/02
Filed: 1988-03-10
Abstract: PURPOSE:To decrease undesired vibration and therefore reduce noise by adding inertia to the shaft of a step motor to produce no torque coaxially to the step motor shaft after formation of the groove of a lead screw. CONSTITUTION:An inertia 18 is added to a lead screw 15. In other words, the inertia 18 is added coaxially to the screw 15 and works as the total inertia of a step motor 19 which produces no torque. As a result, the inertia 18 functions to change undesired intermediate resonance points at start/stop of the motor 19 and to improve the damping action to ensure smooth start characteristics. At the same time, the reaction caused by a carriage 12 at the stop time can be reduced. Furthermore, the motor 19 can be stabilized at a point having the energy of a low level with increase of the inertia at the drive side. Then hysteresis can be reduced.

Title: Floating point multiplying circuit
Inventor: AMAMIYA TAKESHI
IPC: G06F7/52
Filed: 1990-03-08
Abstract: PURPOSE:To improve the throughput of multiplication by selecting any one of the data of a multiplied result, data shifting one digit to left in the matissa part of the multiplied result and the output data of an arithmetic result register storing data, for which the multiplied result is normalized by a normalizing shifter, according to a normalizing amount deciding signal. CONSTITUTION:Based on floating point data 10 and 20 to be inputted to a multiplier 1, a normalizing amount deciding circuit 6 calculates the normalizing amount of a multiplied result 100 from the multiplier 1. The circuit 6 outputs 00 and a circuit 8 selects the output of an intermediate result register 2. When the normalizing amount is one digit on the left side, the circuit 6 outputs 01 and the circuit 8 applies the mantissa part of an output 200 from the register 2 to a left-side one digit shifter 5 and normalizes the mantissa part by shifting one digit to the left side. Then, normalized data 500 is selected and outputted as an output signal 800. When the normalizing amount is neither 0 digit nor 1 digit, the circuit 6 outputs 1X and the circuit 8 selects normalized data 400 from an arithmetic result register 4. Thus, the through-put of a floating point multiplying instruction can be improved.

Title: Electric cable having self-repair protective function

IPC: H01B3/30
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To allow self-repair after mechanical damage that causes disconnection in one or more coating layers by providing a cable comprising a core and one or more coating layers with an internal layer containing a self-repair substance having a predetermined coagulating property and controlled flowability. SOLUTION: An internal layer of a self-repair layer 3 having a predetermined thickness is preferably formed between an insulating layer 2 of a polymer composition or the like covering a core 1, and an outer protective sheath 4, and it may be arranged between the core 1 and the insulating layer 2 or two insulating layers. A self-repair substance has a predetermined coagulating property and spontaneously forms bonds between molecules again after its rupture, and its flowability is controlled in a manner that does not cause substance loss due to drain from an end of the cable or leakage from a ruptured position. The self-repair substance is preferably a dielectric that can recover electrical insulation after the rupture, and an amorphous polymer of a high viscosity liquid or a semi-solid which is physicochemically inert to an abutting plastic.  Accordingly, even if rupture occurs in the coating layer, it can be used for a predetermined period.

Title: Device for preventing gas fuel evaporation
Inventor: FUKAMI AKIRA
IPC: B01D53/44
Filed: 1979-05-10
Abstract: PURPOSE: To bring an active carbon temperature close to the atmospheric temperature, accelerate adsorption-desorption reaction, and thereby enhance a cainstor capability by a method wherein a part of heat exchanger fins are made to contact with active carbon and at the other part fins are protruded out of container.  
     CONSTITUTION: When an automobile is stopped, fuel vapor from the tank is passed through pipe 9, holes of punched metal 4b, and glass fiber layer 6b, and is admitted into active carbon layer 7 to be adsorbed. At this time, adsorption heat is dissipated through good conductivity heat exchanger fins 5 which contact the active carbon at one part and are extruded out of canistor at other part. This relaxes temperature rise in the canistor internal and lowers a maximum temperature. When the fuel vapor is to be desorbed, heat required for desorption is supplied through the heat exchanger fins 5 from the external of the canistor. This results in gradual temperature fall in canistor internal and raises a minimum temperature.
