Title: Knife mark inspecting device
Inventor: OOHATA HIKARI
IPC: G01N21/89
Filed: 1981-02-13
Abstract: PURPOSE:To lighten the positioning accuracy of a device, and also to elevate the inspection capacity, by detecting a light beam from an optical image bearing a knife mark generated by being irradiated by a band-like light beam through a cylindrical lens and a slit, through 3 prescribed slits. CONSTITUTION:A light beam emitted from a light source 1 is made a band-like light beam by a cylindrical lens 2, and diagonally irradiates a knife mark 8 on a veneer 9 carried on the belt conveyor. The knife mark 8 is made to form an image as a dark line on a screen 5 through a slit 3 and a cylindrical lens 4. Its optical image is detected by a photomultiplier 7 through 3 slits which are in parallel with the knife mark 8 and make an angle of + or -2 deg. against it. In this way, not only the positioning accuracy of a device is lightened but also its inspection capacity is elevated.

Title: Rectifier circuit
Inventor: HARA YASUSHI
IPC: H03D1/18
Filed: 1991-01-22
Abstract: PURPOSE:To improve rectifier efficiency and to improve a temperature feature in an AC signal rectifier circuit. CONSTITUTION:A capacitor C3 and a ground resistance 3 are connected to the collector of a transistor TR1 which is base-grounded. When an input signal is positive, the transistor TR1 is turned on and it operates as an impedance converter so as to charge the capacitor C3. At that time, most current flowing into an emitter flows into the collector and voltage between the emitter and the collector is saturated. When the signal is negative, the transistor is turned off and the charge of the capacitor C3 is discharged through the resistance R3. Since impedance is converted by using base grounding, efficiency is satisfactory. Then, the saturation of the transistor is used and the temperature feature is improved.

CONSTITUTION:When printing characters, a lead screw 29 is reversely rotated by one rotation by the motor 28, a paper is fed by a one-line amount by the contact of a ratchet roller 39 with a ratchet gear 36 through a clutch gear 37 and a paper-feeding gear 38, and a carriage is returned to a home position HP. In this case, the clutch gear 37 prevents the ratchet gear 36 from being rotated, so that the paper is prevented from being fed reversely. When recording an image, the lead screw 29 is rotated by 2/3 of rotation, whereby a line space of 2/3 of the above is obtained, and solid printing required for recording the image can be performed. Accordingly, a printing cycle can be performed by forward and reverse rotations of a single drive source, and both printing of characters and recording of images can be performed.

Title: Table device
Inventor: UEDA KATSUNOBU
IPC: B23Q1/00
Filed: 1988-02-02
Abstract: PURPOSE:To move a moving table at a high speed even with a small-size driving source and simplify a controlling system by providing a balancing means for loading a force which oppositely balances with a force that the mass of a moving-table driving source and a moving body receives due to gravitational acceleration, on the moving body. CONSTITUTION:The weight of a moving body consisting of a moving table 2 and members which move in the same direction following the table 2 is balanced with a weight 14 via pulley blocks 13. Hence, when the table 2 moves upward, although a load due to gravitational acceleration is applied in the moving direction, this load is offset by the load in the opposite direction of the weight 14. On the contrary, at the time of lowering the table 2, a weight due to the gravitational acceleration is added to the table 2, which however is also offset by the weight of the weight 14 balancing therewith. Thus, even when the table 2 is moved in the direction of gravity, always no gravitation is applied irrespective of the moving direction of the table 2 enabling the drive of the table 2 with a slight thrust of the same value, without requiring a high- output driving motor thereby, without need for providing a large table device.

Title: Semiconductor integrated circuit device
Inventor: INOUE YOSHIO
IPC: H01L21/82
Filed: 1990-02-01
Abstract: PURPOSE:To make it possible to transfer signal change without wrong operation even if it is a change of high frequency input signal by installing a capacitor element which outs off a direct current component to a cell built-in a gate array and a feedback amplifier. CONSTITUTION:A gate array is provided with a capacitor element 4 which outs off a DC component of signal change and a feedback amplifier in the next stage of the capacitor element 4. Since the capacitor element 4 is designed to cut off a DC component of input signal in this case, a gate input potential is constantly biassed to a threshold potential by a resistor element 3 which constitutes the feedback amplifier. The input signal change transferred by way of the capacitor element 4 is converted into the signal change to the threshold potential. The input signal converted into the signal change to the threshold potential is transferred to the subsequent stages amplified by the next stage feedback amplifier. This construction makes it possible to transfer even high frequency signal change.
