Filed: 1997-06-23
Abstract: PROBLEM TO BE SOLVED: To automatically set the current time of a portable information communication processor to the current time of a host just by connecting the communication processor to the host without performing a manual time setting operation, to eliminate the waste of time due to the manual time setting operation and also to improve the operability of the communication processor. SOLUTION: The data held by a built-in clock of a portable information communication processor 102 are automatically updated based on the current time data received via a data receiving part 103 when the processor 102 is connected to a communication network. Thus, the error can be corrected between the current time information on a host 10 and the current time information on the processor 102. As a result, a user has not to perform a manual time setting operation. In such a constitution, the operability of the processor 102 is improved and also the reliability is improved for the management of data on a time base. Furthermore, the correction of time can be notified to the user in various ways.

Title: Wire electric discharge machine
Inventor: YAMAUCHI MOTOO
IPC: B23H7/10
Filed: 1987-07-02
Abstract: PURPOSE:To prevent a powder brake from generating unstable torque by driving the powder brake, which applies torque to a main tension pulley, to be rotated by a forcedly driving motor even in stopping of electric discharge machining. CONSTITUTION:In the time of normal electric discharge machining, generated torque of a powder brake (main tension brake) 5 is transmitted to a main tension pulley 4, and tension is given to a wire electrode 3. In the time of stopping the electric discharge machining, rotation of the main tension pulley 4 stops, but here a forcedly driving motor 6 transmits its turning effect to the powder brake 5 continuing its rotation. The turning effect of this rotation is not transmitted to the pulley 4 by a one-way clutch. Accordingly, even when the electric discharge machining is stopped, because the powder brake 5 continues its rotation and holds the generated torque to a fixed value, tension given to the wire electrode can be always stably obtained.

Title: Twist drill
Inventor: HOSONO HIDEJI
IPC: B23B51/02
Filed: 1987-07-02
Abstract: PURPOSE:To eliminate the necessity of laborious repetition of a thinning process during repolishing, and to reduce cutting resistance, by shortening a predeter mined range of a recess groove formed along a twisted groove than the lead length of the twisted groove. CONSTITUTION:A twisted groove 2 is formed in the outer peripheral surface of a tool body 1, having a predetermined lead length L1 while a cutting edge 2a is formed in the front end ridge line section of the tool body, and a recess groove 3 which is concave toward the axis of the tool body 1 is formed in the circumferentially center part of the twisted groove 2. The lead length L2 of the recess groove 3 is set to be shorter than the lead length L1 of the twisted groove 2, and the rake angle of a thinning blade 3a is set in a direction which is more than that the lead length L2 of the recess groove 3 would be equal to the lead length L1 of the twist groove 2. In this arrangement, the recess groove 3 is shifted in the direction opposite to the rotating direction by repolishing so that the length of the cutting edge 2a becomes shorter. The lead length of this recess groove 3 is set to a value which is three times large as the diameter of the drill, and is made to be equal to the lead length of the twisted groove 2 on the base end side.

Inventor: TANABE AKIO
IPC: G02B6/255
Filed: 1993-06-11
Abstract: PURPOSE:To provide a method for reinforcing an optical fiber juncture with a heat shrinkable tube without disconnecting optical fibers. CONSTITUTION:This method consists of reinforcing optical fiber juncture with a heat shrinkable tube 2 by putting the heat shrinkable tube 2 on the optical fiber juncture and shrinking the heat shrinkable tube 2 by heating the tube. The temp. drop of the heat shrinkable tube after the shrinkage by heating is measured and the optical fiber juncture covered with the heat shrinkable tube is held fixed until the temp. falls down to the curing temp. of the heat shrinkable tube or below. Then, the optical fiber juncture covered with the heat shrinkable tube 2 is kept fixed up to the curing temp. of the heat shrinkable tube 2 and, therefore, the disconnection of the optical fibers of the optical fiber juncture does not arise.

Filed: 1984-08-08
Abstract: PURPOSE:To obtain a rotary actuator of high performance which is allowed to make constant light incident upon an objective lens and set up a turning range to a tracking following range by using the hollow part of a rotary shaft as an optical path and arranging optical elements to be moved unitedly with the rotary shaft on the inside and outside of the rotary shaft. CONSTITUTION:A mirror 17 turns the direction of light guided from a hole part 16 into the rotary shaft 14 and guides turned light to the outside of the shaft 14 through a window 18 and a mirror 19 guides the light projected to the outside of the shaft 14 to an objective lens 2. The mirror 19 is fitted to the inwall of an objective lens barrel 1 through a fixing board 20 and light from a light source is projected to the lens 2 through an optical path 21. Since the mirrors 17, 19 are fixed on the shaft 14 and the cylinder 1 respectively, these mirrors 17, 19 are moved unitedly with the barrel 1. Since the optical path 21 is also moved unitedly with the barrel 1, no light loss due to kick is generated even if the lens 2 is moved, and the whole turning range of the lens 2 can be used as a tracking following range.

IPC: G21F9/06
Filed: 1990-06-25
Abstract: PURPOSE:To shorten work time for replacement and reduce worker's danger of exposure to radiation, by providing a filtrate extraction pipe extending bottomward from a piping plate. CONSTITUTION:A filtrate chamber 5 is formed between a piping plate 3 and a housing top lid 4 by providing a hollow yarn film filter 2 toward the axis direction in a vertical cylinder housing 1 having a filtrate supplying pipe 6 and the top lid 4 above the piping plate 3 on the filter. A filtrate extraction pipe 18 is so fixed that its one end opens in the piping plate 3 and the other end penetrates the side wall of the housing 1 below the piping plate 3 and extends to the outside of the housing. Thus, the replacement of the used filter 2 is managed by dismantling a flange fastener 9 between the housing 1 and the top lid 4 to pull it out upward, and so working time is shortened and the possibility of exposure to radiation accompanying the work is reduced.
