IPC: G11B21/02
Filed: 1986-05-30
Abstract: PURPOSE:To relieve the load of a step motor by fitting a roller to a drive piece and pushing the drive chip onto the slot of a screw thread via the roller. CONSTITUTION:In driving a stop motor 1, the screw thread 2 coupled directly to the rotary shaft of the step motor 1 is driven and the roller 6 of a needle rod 2 pressed onto the slot of the screw thread 2 is being driven in response to the drive of the screw 2, the needle rod 3 is moved forward or backward in response to the drive direction of the screw thread 2 to move the carriage main body 4 forward or backward. Thus, since the torque for carriage drive is delivered via the rotation of the roller, the torque is delivered smoothly. Thus, the load of the step motor is relieved and wear is reduced.

Title: Semiconductor laser device
Inventor: TANAKA NOBUKAZU
IPC: G11B7/125
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To monitor outputs of diffused beams and reduce beam operating current for use in recording and reproducing an optical disk, by providing a light receiving element for receiving peripheral light beams among the diffused beams emitted from a laser chip in the vicinity of a light emitting window. SOLUTION: A light receiving element 104 having a doughnut-type light receiving surface capable of directly catching peripheral light beams 103, which are not employed for recording and reproduction of an optical disk among diffused beams 102 emitted from a front light emitting point of a laser chip 101, is disposed on the peripheral portion of a window glass 105 serving as a beam emitting window. The light receiving element 104 can narrow the diameter of a beam 107 emitted from a semiconductor laser 106 and function to shield harmful light which becomes stray light within the optical system of a pickup. That is, beams in the center position suited for recording and reproduction of the optical disk are emitted from the semiconductor laser and efficiently converted into collimate light beams by a collimator lens.

Title: Back light for panel
IPC: G02B6/00
Filed: 1992-04-20
Abstract: PURPOSE:To make the surface light emission of a screen display device uniform by forming a reflection pattern on a light guide plate so that the reflection factor is higher nearby both end parts of a tubular light source than nearby the center part of the light emission part. CONSTITUTION:Liquid crystal 18 and the tubular light source 24 are united by a module cover 26 to constitute a liquid crystal display device. The specific reflection pattern 25 is formed on the light guide plate 23 so that the reflective index is higher nearby the end parts of the tubular light source 24 than nearby the center part of the light emission part 24a, so even when an effective light emission part parallel to a light guide-in end part 23a is made nearly as long as the tubular light source 24, the periphery of a light non-emission part 24b is prevented from becoming darker than the periphery of the light emission part 24a. The outward shape of the liquid crystal display device can be stored almost in a square. Further, the shape of the individual reflection patterns 25 is varied with the distance from the tubular light source 24 to prevent variance in the printing precision of the pattern and fringes due to moire, thereby obtaining uniform brightness.

Filed: 1979-10-01
Abstract: PURPOSE: To obtain the energy collector that is small-sized, inexpensive and, efficient, by attaching a heat exchanger with a fan to the backside of the energy collector to subject the heated air to heat exchange with water.  
     CONSTITUTION: The heat exchanger 2 with a fan and an air duct 3 are attached to the backside of the solar energy collector 1. The air that has collected energy and has been heated is led through the duct 3 to the heat exchanger 2 where it is subjected to heat exchange with the cold water, which is heated and is stored in a hot water reservoir (not shown). If it is desired to further collect solar energy, a solar energy collector 1" without the heat exchanger 2 is arranged adjacent to the solar energy collector 1 with the heat exchanger, an air outlet of the collector 1 is connected with an air inlet of the collector 1", and an air outlet of the collector 1" is connected through the duct 3 to the heat exchanger 2 to effect heat exchange. Therefore, even if there are plurality of collectors without heat exchangers, heat exchange becomes possible by only one heat exchanger.

Title: Operating method for bag filling machine
Inventor: OKIMOTO NOBORU
IPC: B65B43/50
Filed: 1991-03-09
Abstract: PURPOSE:To avoid improper detection, and improve productivity by a method wherein the opening condition of a bag is detected in an opening process by utilizing cases with and without negative pressure occurring in the pipe to a vacuum pump and, if no negative pressure is detected, the bag is filled with its contents and sent back to the opening process to repeat the aforesaid detecting action. CONSTITUTION:A detecting vacuum pressure switch 8 is for detecting the existence of negatice pressure when a bag 2 is opened in an opening process and, if any negative pressure is detected, the bag is filled with its contents, its opening is sealed and the bag is sent to the next process. On the other hand, if no negative pressure is detected, the bag 2 is filled with the contents, its opening is left unsealed, the bag is sent back to the opening process without being carried out and by being clamped by a table clamping means and the aforesaid detecting action is repeated. Since this negative pressure detection is numerically performed by the instructions from a sequencer 7, independently of the shape and size of the bag 2 or changes in the material, the aforesaid method provides a proper and efficient inspection and freedom in mounting a detecting vacuum pressure switch 8.

Filed: 1995-04-26
Abstract: PURPOSE: To improve the detecting accuracy in a simple constitution by holding a differential signal of a differential circuit outputting a difference of output voltages of a pair of piezoelectric elements for every predetermined integral cycle of an oscillation cycle of an oscillation circuit. CONSTITUTION: A differential signal 61 from a differential circuit 6 which outputs a difference of output signals 43 and 44 converted from voltages by piezoelectric elements 41, 42 is held by a holding circuit 10 and output as a holding voltage 11. The differential signal 61 is held with a rise timing of an oscillation signal 51 of an oscillation circuit 5 and held once every cycle afterwards. Accordingly, the holding voltage 11 can be obtained approximately at a peak point of the differential signal. Then, the holding voltage 11 is smoothed by an LPF 8, thereby an angular velocity signal 81b is obtained. If an oscillation frequency of the oscillation circuit 5 is high to a certain extent to a jitter frequency, a step difference of signals appearing in the output of the holding circuit 10, namely, the difference of output values resulting from samplings becomes small.

Title: Method for continuously casting thin cast slab
Inventor: KUMAKURA SEIJI
IPC: B22D11/128
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To provide a continuous casting method of a thin cast slab with an unsolidified rolling reduction method, in which the rolling reduction causing the trouble on the operation is avoided and the length in the unsteady part is shortened as little as possible. SOLUTION: The unsolidified rolling reduction continuous casting method for producing the thin cast slab, is executed by drawing out the cast slab 2 which is formed in a mold 1 in a vertical and bending type continuous caster and of which the inside is in the unsolidified state, and applying the rolling reduction while supporting with guide rolls. The cast slab 2 is vertically supported just below the mold 1 with two to five sets of support rolls 4 so as to become parallel with the inner surface of the mold 1 without applying the rolling reduction and the unsolidified rolling reduction is applied with rolls 4 following the support rolls. In the way, the cast slab can smoothly be drawn out and the strain caused by the bending of the cast slab can be made small.  Therefore, it can be eliminated that in such a case of applying the rolling reduction just below the mold, the contact between the cast slab and the mold is worsened and the operational troubles such as longitudinal crack, breakout, are caused.
