Title: Recording head inclination adjusting device in ink jet recorder
Inventor: SUGIYAMA HIROSHI
IPC: B41J25/316
Filed: 1992-09-21
Abstract: PURPOSE:To facilitate an operation and prevent a shift of an adjusted position of a recording head to always keep a recording condition for a minimum image disturbance by a method wherein a part corresponding to a top surface of a pressing force receiving part has an appropriate curved-face structure. CONSTITUTION:A recording head 1 is fixed to a movable mount 2 by fastening screws 18, 19. At this time, a pressing force receiving part 21 on the recording head 1 comes into circular contact with a spacer 23 at approximately the same radius of curvature. Therefore, if a considerable force is applied from above by the screws 18, 19 with the lower surfaces of heads of the screws 18, 19 in nonparallel to the top surface of the recording head 1, the center of the circular contact of the pressing force receiving part 21 easily positionally shifts to always position the recording head 1 invariably just on the movable mount with respect to the center of curvature of the circle. Thus, the recording head 1 is always pressed down vertically without a corrective force acting to shift its adjusted position.

Title: Linear induction motor
Inventor: NIHEI HIDEKI
IPC: B66B9/02
Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To effectively cool a linear induction motor without ensuring an excess space by a method in which the air is convected in spaces which are formed between a plurality of U-shaped frames used to hold a primary side and the primary side is cooled. SOLUTION: A linear induction motor is composed of five frames 4 formed by combining three square beams each in such a way that every horizontal cross-sectional shape becomes U-shaped. The frames are arranged horizontally at equal intervals, spaces are formed between the respective frames 4, two primary-side cores 1 each on which coils 2 are wound at the inside are fixed so as to be faced with each other, and a secondary conductor 3 is installed between the primary-side cores 1. Then, when a primary side which is composed of the cores 1, of the coils 2 and of the frames 4 is moved in the up-and-down direction, the open air is circulated inside the frames 4, the open air is blown directly on the coils 2 from the upper direction so as to flow out to the direction of every arrow from the spaces between the five frames 4, and the open air cools the coils 2. As a result, the cooling performance of the linear induction motor can be enhanced without making its external dimensions large.

Title: Driving of gas concentration sensor
Inventor: KURUMIYA YOICHI
IPC: G01N27/41
Filed: 1988-10-06
Abstract: PURPOSE:To enable measurement at a high consn. area along with a higher measuring accuracy at a low consn. area by raising a monitoring voltage to be applied to a solid electrolyte having an icon conductivity in proportion to a sensor output current while the ratio thereof is reduced gradually. CONSTITUTION:Operational amplifiers OP1-OP3 convert an output current Ic of a sensor S into a voltage signal to create a voltage Vb as base of a sensor monitoring voltage Vs through a feedback circuit M (Fig. 3). Operational amplifiers OP4-7 convert an amplification factor according to a magnitude of a voltage Vb to change the rate of a change (rise) in the voltage Vs (Fig. 4). With such an arrangement, a rising rate of the voltage Vs to be applied to a solid electrolyte is reduced gradually by stages in proportion to the current Ic as indicated by monitoring voltage curves Vso1 and Vso2 in Fig.(a). Hence, even when the voltage Vs is lowered at a low concn. so as to minimize effect of a dark current, the inclination of the curve is limited and the extension of the inclination can not hit an output current curve A before a limit current is reached, thereby enabling the extending of the voltage Vs to a limit current area at a high gas concn.
