Inventor: NIHEI GUNJI
IPC: F03G5/00
Filed: 1984-04-02
Abstract: PURPOSE:To obtain the human powered driving device for rotation, which is light in weight and easy to drive, by a method wherein two sets of rubber strings are wound around a cylinder to generate a couple and the rubber strings are pulled so that the tangentials of both strings are parallel and the directions of the forces of pulling are contrary mutually while the cylinder is idled when the strings are returning to their initial conditions. CONSTITUTION:When a grip 7 is pulled into the arrow sign direction in the diagram, the string 4 is pulled with a speed, double of the pulling speed of the grip 7, and the cylinder 2 begins to rotate. In this case, pawl gear 2-3 at the end face of the cylinder 2 applied with the pulling force is being meshed with a pawl 3-1, therefore, a pawl arm 3 is rotated together and a rotation driving shaft 1 is also rotated into the arrow sign direction by turns corresponding to the turns of the string. Next, when the pulling force is released, the rubber string 5 around a small cylinder 2-2 is moved reversely and the pawl 3-1 is released, therefore, the grip 7 returns to the initial position thereof together with the cylinder 2.

IPC: A47J27/21
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To effectively prevent the outflow of a liquid inside a vessel at the time of falling-down of the vessel body. SOLUTION: The pressure discharge port 21 of an electric water heater is provided with a filter 23 having a plurality of fine pores through which a gas can be passed but a liquid 4 cannot be passed; and even if the pressure inside the vessel 5 is risen when the vessel body 1 is fallen down, only the gaseous pressure is discharged through the filter 23 to the outside of the vessel body 1. Thus, the deformation of the outer packaging part 3 or the cover 10 due to the pressure rise can be prevented, and also the outflow of the liquid 4 through the vessel packing 13 part can be prevented.

Title: Constant-current circuit
Inventor: YOSHIDA YOSHIHIRO
IPC: G05F3/26
Filed: 1981-04-30
Abstract: PURPOSE:To obtain the titled circuit which can operate under low voltages and can be constructed with integrated circuits, by controlling the electric current in such a way that the potential difference across both ends of a resistance will  be equal to the offset voltage of a differentially amplifying circuit which is generated because of the difference in current density. CONSTITUTION:A constant current is obtained by controlling an electric current IREF flowing into a resistance R12 in such a way that a potential difference DELTAVBE across both ends of the resistance R12 will be equal to offset voltages of differentially amplifying circuits Q1-Q4 which are generated because of the difference in current density. In the constant-current circuit, the difference in current density of a differential amplifier composed of transistors Q1 and Q2 is produced by a current mirror circuit composed of transistors Q3 and Q4. Since DELTAVBE due to the difference in current density and R12XIREF operate so as to balance with each other under the same condition, operations under low voltages become possible.

Title: Force converter
Inventor: SUZUKI KENICHIROU
IPC: H01L29/84
Filed: 1984-04-03
Abstract: PURPOSE:To implement a highly accurate force converter readily, by performing position alignment in the direction of one dimension, i.e., only in the direction of a free boundary of a strain yielding body, with respect to the position relations between force transmitting bodies and the strain yielding body and between the strain yielding body and gage resistors. CONSTITUTION:Gage resistors 1 are formed in a region held by two force transmitting bodies 7 on the surface of a strain yielding body 30. Stress acting on the gage resistors 1 has a constant magnitude with respect to the direction in parallel with the long side of the strain yielding body. The stress is hardly changed in the direction perpendicular to the long side. In this constitution, the force converter has a constant value in the broad area of the strain yielding body 30, which is held by contact ends 32 of a pair of the force transmitting bodies 7. The respective contact surface of a pair of the force transmitting bodies are measured along the long sides. The position aligment is performed so that the distances from boundary sides 34 become equal. The gage resistors 1 are placed at arbitrary positions of the surface of the strain yielding body held by a pair of contacting ends 32. Only by this way, the highly accurate force converter can be obtained.

Title: Front end resist position adjuster for image recorder
Inventor: HIRATA KAZUHIRO
IPC: G03G15/00
Filed: 1987-03-20
Abstract: PURPOSE:To permit easy and quick setting of a front end resist position by recording plural pieces of the sample images corresponding to a part or the whole of the graduations of a setting means for variably setting the front end resist position simultaneously, emitting the sample image corresponding to the desired resist position from these images and setting the resist position. CONSTITUTION:An operator inputs the output command of the sample images by operating a start switch 5. Then, an image processor 4 generates the image data of cross lines A-E in the same state as the state of the graduations of a setting switch which are successively shifted in 5 stages. On the other, a control processor 3 feeds paper 6 at the same timing when the switch is set at the min. graduation regardless of the set position of the switch 2. Five pieces of the cross lines A-E corresponding to the number of the graduations of the switch 2 are, therefore, recorded at the spacings corresponding to the spacings between the respective graduations. Execution of the recording always from the desired resist position is thereafter permitted if the switch 2 is held set in the position of the min. graduation unless the conditions such as expansion and contraction of the paper change.

Title: Apparatus for damping vibration of column with double structure
Inventor: NOGUCHI MITSUO
IPC: F16F7/116
Filed: 1981-05-06
Abstract: PURPOSE:To obtain an excellent vibration damping effect with a weight being not very heavy, by arranging the weight between an inner column and an outer pipe and at the upper end thereof through a coil spring. CONSTITUTION:The coil spring 3 and the weight 5 are arranged between the outer pipe 2b and the inner column 2a. The clearance 6 between the outer pipe 2b and the weight 5 should be equal to the clearance 7 between the inner column 2a and the weight 5. As a result, in the case the column 2 is vibrated, the weight 5 collides with the outer pipe 2b and the inner pipe 2a, so that compared with the prior apparatus the dissipation of the energy due to the collisions is large. Accordingly, a vibration damping effect larger than that of the prior apparatus can be effected.
