Title: Arm-worn portable equipment and adjusting method for its band length
Inventor: YASUKAWA HISAAKI
IPC: G04G21/02
Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To enable a device main body to be surely and quickly worn on the arm and to enable a wristband to be easily attached to and removed from the device main body. SOLUTION: In an arm-worn pulse wave measuring device, a wristband 12 is connected along the twelve-hour direction of a device main body 10 via a band connecting shaft 14 which can be mounted in and removed from a holding hole 171 in the device main body 10. A band fastener 60 is mounted along the six-hour direction of the device main body 10 to hold a part of the wristband 12 folded back at the band fastener 60. A locking piece 123 covering the end face of the band is bonded to a band end 121 with an adhesive to form a stepped level 127. Thus the stepped level 127 of the wristband 12 is hooked to a band passage 611 in the band fastener 60, preventing the band end 121 from being inadvertently loosened from the band fastener 60.

Title: Dot impact serial printer
Inventor: TSUJI TAKAO
IPC: B41J33/26
Filed: 1989-06-23
Abstract: PURPOSE:To prevent a printing wire from cating, to reduce a breakage accident, to eliminate a slack of a ribbon and to prevent a ribbon jam by providing an installation type ink ribbon cassette, a ribbon guide mechanism for generating a frictional force to the ribbon to move a pulley through the ribbon passing therein in front of a printing head and a detector for detecting position of the pulley of the ribbon. CONSTITUTION:When a printing head 6 is conveyed from left to right or from right to left of a ribbon cassette 1, a slide pulley 3 can be moved oppositely to a carriage 8 by a frictional force between the ribbon 2 of the front face of the head 6 and a ribbon guide mechanism 10. If a right side slide pulley position detector 11-b detects the pulley 3 when the head 6 is disposed at the right side. When the head 6 is disposed at the left side, a left side slide pulley position detector 11-a detects the slide pulley 3, printing is not conducted, but only the head 3 is conveyed. Thus, when the head 6 is disposed at the right side, the pulley 3 can be returned to the left side, while when the head 6 is disposed at the left side, the pulley 3 can be returned to the original positional relationship of right side.

Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of blurring and artifact even when an overlapped image or a subtraction image is generated by making an interpolation arithmetic means perform an interpolation arithmetic by means of a secondary or higher order function. SOLUTION: The interpolation image data Q1 and Q2 on the interpolation points xP1 and xP2 corresponding to the position of an interpolation point P0 set in the (x) axis direction are defined as Q1 =(1-Tx )DA+TXDB and Q2 =(1-TX) DC+TXDD based on the image data DA, DB, DC and DD on the existing pixels SA, SB, SC and SD (unit grids forming a square grid) of the converted images of nearby four points surrounding an interpolation point P6 corresponding to an image pixel point. Thus, the linear interpolation is decided based on the data Q1 and Q2 . Then a linear interpolation arithmetic is performed in the (y) axis direction of the point P0 based on an equation Q0 =(1-Ty )Q1 +Ty Q2 where the data Q1 and Q2 are used. Thus, the interpolating image data Q0 are obtained.

IPC: H02P7/288
Filed: 1983-09-02
Abstract: PURPOSE:To obtain a drive circuit for a motor which is inexpensive and has a low voltage drop by using a semiconductor element only for a switching and a relay for the other. CONSTITUTION:When a motor M is rotatably driven in a positive direction, signals are outputted from the output terminals (1) and (4) of a control circuit C to energize a solenoid of a relay RY1 to connect a contact, and to conduct a transistor TR4. On the contrary, when the motor M is rotatably driven in a reverse direction, a signal is outputted from the output terminals (2) and (3) of the control circuit C to energize a solenoid of a relay RY3 to connect a contact, and to conduct a transistor TR3. Thus, the number of large current semiconductor elements is reduced to provide a drive circuit for the motor which has low voltage drop inexpensively.

This bottomed cylindrical body is set inside the female die 7 which has the square peripheral part 4 of bottom and its inner wall surface 5 is enlarged in the tapered state toward the opening part, is brought the male die 9 in contact with the opening peripheral edge of the cylindrical body having bottom and with its bottom wall 3, and is compressed and the edge is formed. Next, the bottomed cylindrical body is pressed in the dies 15 and its outer periphery is formed straight and so the opening peripheral edge is prevented from becoming thinner. In such a way, because the plastic deformation degree is comparatively little and the bottom edge part is formed squarely, so the validity as the piston is long. And the high accurate finishing of the outside wall surface is executed, and the mass production is suitable because the working process is little.

Abstract: PURPOSE: To cut the wound wire at the portion near a terminal and to begin the next wire-winding operation immediately after the previous winding operation, by combining a tension-keeping action and cutting action of wire by a cam at a specified timing.  
     CONSTITUTION: A tip 112a of a sliding member 112 is pushed toward a small block 108 against a force of a pulling spring 114. Then, a rack gear 115 is moved, a pinion is rotated, and a cutting lever 110 which is extended in the lateral direction is rotated on a vertical shaft. Wire is cut at the vicinity of a terminal with the cooperation of the lever 110 and the final terminal when the lever 110 crosses the wire which has been wound on the last terminal according to the wire-winding pattern of a core. Thereafter, the pushing of the tip 112a of the lever 110 is released, the lever 110 is rotated into the reverse direction and returned to the original position by the action of the spring 114. After the wire has been cut, since the wire is held by a wire holder and is continued from the holder to a wire feeding nozzle in the tightened state, the next winding operation can be readily begun.

Title: Dc power supply circuit with overvoltage protecting function
Inventor: UCHIDA KOICHI
IPC: G05F1/10
Filed: 1985-07-25
Abstract: PURPOSE:To cut off the output voltage when it exceeds a prescribed level by connecting an overcurrent protecting circuit containing a latch function and a discharge tuber which flows a high discharging current at a prescribed level of voltage to an output terminal. CONSTITUTION:A discharge tube 3 is connected to an output terminal T0 to flow a current at a prescribed level of voltage. Therefore the tube 3 functions to flow a short circuit current to a resistance R0 when the voltage of the terminal T0 exceeds a prescribed level even in case the constant voltage control function of an overcurrent protecting circuit 2 is lost. When an overcurrent flows to a load circuit, the current flowing to a switching transistor TRQ increases suddenly. Then a current limiting circuit monitoring the terminal voltage of a resistance R works to supply the detection signal latched at an L level to a drive circuit 1. Thus the TRQ is turned off to prevent the damage by burning with a DC power supply circuit or/and the load circuit.
