Title: Picture image formation device
Inventor: NAGATSUMA TORU
IPC: B65H1/18
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To steplessly detect residual quantity of sheets accumulated on a paper feeding part without increasing the number of parts, complicating a mechanism and complicating a control circuit. SOLUTION: This device checks a state of a paper surface position detection detection sensor 4 when a paper feeding cassette is set and raises a bottom plate 1 until the paper surface position detection sensor 4 is put on when it is off (not detected), Time to reach a state where the paper surface position detection sensor 4 is put on from starting to rise is counted in a rising process of the bottom plate 1. Thereafter, sheet accumulated quantity (n) is assumed from this counted value (t) and rising speed of the bottom plate 1, and it is recorded in a non-volatile memory. When picture image forming motion is started, the sheet accumulated quantity (n) is decreased for each of the paper feeding motion, and recording value of the non-volatile memory is renewed. This newest recording value is regarded as sheet residual quantity at the current point of time. The motion is repeated in the case when the paper feeding cassette is removed when an electric power source is on.

Title: Highly-responsive angular acceleration detector
Inventor: HONMA ISAO
IPC: G01M17/007
Filed: 1988-04-20
Abstract: PURPOSE:To perform highly responsive angular acceleration detection by means of a torque meter using a piezo type load washer. CONSTITUTION:A piezo type load washer 13 is inserted between the circumferential surfaces of a driving-side flange 9 and absorbing-side flange 12. A rotational inertia body is connected with the flange 12 through an absorbing shaft 10 and an angular velocity is given to the other flange 9 through the shaft end coupling 8 of a dynamometer. A load is applied to the washer 13 in the direction of the rotational tangent of the flange 9 and the washer 13 outputs the load after converting the load into a change in electric charge. The detect signal of the washer 13 is constant-changed by means of the quantity of inertia of the rotational inertia body and fitting radius of the washer 13 and then highly- responsive angular acceleration detection is realized.

Filed: 1985-05-04
Abstract: PURPOSE:To improve the thermal efficiency of an engine, according to the method wherein rotation of a crank shaft, connected to a piston, is transmitted to a second crank shaft through a gear train to fetch a power. CONSTITUTION:A crank shaft (first crank shaft) 5 is pivotally secured to a portion where another crank shaft (second crank shaft) 1 of well-known gasoline engine is coupled to a connecting rod 6 connected to a piston 13, and the one end of a crank pin connecting rod 6 of the shaft 5 is coupled to the above coupling portion.

Title: Controller for dc motor
Inventor: SAITOU KUNIO
IPC: H02P7/298
Filed: 1978-08-09
Abstract: PURPOSE: To perform the weakened field drive of a DC motor with a high power- factor without the failure in commutation, by detecting that the control delay angle is minimum in power running and that the armature voltage of the motor is constant in regenerative braking.  
     CONSTITUTION: In the power running, a running/braking discriminator 11 energizes a relay 84 to close a contact 86 and open a contact 87. The motor is then accelerated. When the control delay angle of an armature thyristor 1 falls below a minimum advancement angle, a minimum control delay angle detector 10 supplies an output signal to a limiter 83 to start the weakened field drive to raise the power-factor. In the regenerative braking, the running/braking discriminator 11 deenergizes a relay 84 to open the contact 86 and close the contact 87. The armature voltage is compared with a reference voltage -E by a subtracter 82, whose output is applied to the limiter 83 to perform the weakened field drive as well as in the power running. The reference voltage for the armature voltage is set near the minimum value of the voltage of power to prevent the failure in commutation.

Title: Drawing of solid from hardened cement material
Inventor: YAMAMOTO TAKASHI
IPC: E02D9/02
Filed: 1982-06-07
Abstract: PURPOSE:To easily draw steel pipes, etc., out of a hardened cement material placed in contact with the surface of the solid material by providing a layer composed mainly of a cement setting retarder and a leaching regulator in advance on the surface of the solid material, e.g., the steel pipe, etc. CONSTITUTION:A layer composed mainly of a cement setting retarder (e.g., an oxycarboxylic acid or its derivative, a polyol complex, etc.) and a leaching regulator (e.g., carboxylmethyl cellulose, polyvinyl alcohol, polyacrylic acid, etc.) is provided on the surface of a stel pipe 2, and then concrete 3 is placed into a formwork 1. Since the leaching regulator gradually dissolves in contact with the concrete to cause the retarder to leach, no hardening of concrete occurs in and near the surface of the steel pipe 2 and thereby the steel pipe 2 can be separated without causing the breakage of the surface layer of the concrete by weak forces.

Title: Semiconductor photodetector
Inventor: MAKIUCHI MASAO
IPC: H01L31/10
Filed: 1990-04-16
Abstract: PURPOSE:To lessen electrostatic capacitance and inductance and perform a response at a superhigh-speed by impressing reverse bias voltage to a pin photodiode which is equipped with a p-type impurity introduction region having a small area as a structure element and further, impressing sequential bias voltage to the pin photodiode which is equipped with a p-type impurity introduction region having a large area as the structure element. CONSTITUTION:A pin photodiode PD1 is composed of an n-type conductive semiconductor layer 2, an i-type photoabsorption semiconductor layer 3, and a p-type conductive semiconductor region 5A or the like. As shown obviously by the p-type region 5A, it has a remarkably small pin junction area and pin photodiodes PD2A and PD2B have remarkably large pin junction areas in comparison with the pin photodiode PD1. Then bias voltage is impressed to a connecting electrode 8A for taking out a photoelectric current so that its electrode is negatively polarized and also to a connecting electrode 8B for taking out the photoelectric current so that its electrode is positively polarized. Thus parasitic inductance and capacitance are exceedingly lessened and the deterioration of characteristics is prevented.
