IPC: G06F3/043
Filed: 1988-11-11
Abstract: PURPOSE:To easily execute arithmetic by detecting oscillation, which is inputted by an oscillating pen, by plural sensors to be provided on an oscillation transmitting board, subtracting an oscillation transmitting time, which is from a stored reference point, from an obtained oscillation transmitting time and obtaining a coordinate input point. CONSTITUTION:A user has an oscillating pen 3 in a hand a inputs coordinates in a position on an oscillation transmitting board 8. The oscillation transmitting board 8 transmits the ultrasonic oscillation, which is received from the oscillating pen 3, to oscillation sensors 6a-6c. The information of the measured oscillation transmitting time from a reference point 8a, which is equally distant from the sensors 6a-6c, to the sensors and the true oscillation transmitting time are stored to the memory of an arithmetic and control circuit 1. The oscillation transmitting time from the arbitrary coordinate input point to the sensors 6a-6c is obtained by a signal waveform detecting circuit 9, the circuit 1 subtracts the stored oscillation transmitting time from the obtained oscillation transmitting time and operates the coordinate input point based on the result of the subtraction and the information of the true oscillation transmitting time.

Abstract: PURPOSE:To easily replace a wooden bathtub and floor at less construction cost by a method wherein a bathtub and the floor including a washing space are continuously constructed in a bathroom so as to prevent water leakage, and a wooden bathtub body made of natural wood and wooden floor panels are attached on the surfaces of the bathtub and floor by means of inlay joint. CONSTITUTION:A bathtub 14 and a floor 16 including a washing space are continuously constructed in a bathroom 12 so as to prevent water leakage, and a wooden bathtub body 38 made of natural wood and wooden floor panels 40 are attached on the surfaces of the bathtub 14 and the floor 16 by means of inlay joint to form a wooden bathtub 10. The wooden bathtub body 38 and the wooden floor panels 40 are removable from the bathtub 14 and the floor 16 so as to allow replacement. Thus, as the wooden bathtub can be constructed by attaching the wooden bathtub body and the wooden floor panels on the surfaces of the existing floor, etc., by means of inlay joint without removing the existing bathtub and floor, and the wooden bathtub and the wooden floor panels can be attached on the surfaces of the existing bathtub and floor by means of inlay joint with the shape of the existing bathtub and floor remaining unchanged, the construction is easily carried out. Moreover, the construction cost is kept low because the wooden bathtub body and wooden floor panels can be formed using thick wood scraps.

Filed: 1989-10-31
Abstract: PURPOSE:To satisfactorily reduce the shock applied to a work tool at the time of executing dry run without deteriorating the work accuracy in a normal state by providing a 1st acceleration/deceleration part which performs the acceleration/deceleration in a normal working state and a 2nd acceleration/ deceleration part which performs the acceleration/deceleration at the time of executing dry run to form an acceleration/deceleration part. CONSTITUTION:The parameter of a 2nd acceleration/deceleration part 25b is set larger than the rise-up time or the breaking time of acceleration/ deceleration set by the parameter of a 1st acceleration/deceleration part 26a. The part 26b is switched to the part 26a via a switch SW when the acceleration/ deceleration is required after distribution in a normal working mode. On the other hand, the part 26a is switched to the part 26b at the time of executing dry run. As a result, the work accuracy is never deteriorated in the normal working state and the satisfactory acceleration/deceleration is applied in a dry run state respectively. Then the speed change is reduced and the shock applied to a work tool can be evaded.

Title: Thermal transfer printer
Inventor: MIYAZAWA HISASHI
IPC: B41J2/33
Filed: 1987-11-11
Abstract: PURPOSE:To enable high-speed printing and obtain satisfactory printing quality by providing a transfer process a few times and further preheating a wax ink layer to be transferring by using a thermal head. CONSTITUTION:A heater 1 heats and melts wax ink 2, and a wax ink application thickness adjusting roller 5 controls an application amount. The wax ink is then applied on an application roller 3 and the viscosity is adjusted by a heater 4. After being applied, the wax ink becomes solid with a thickness of about 5mu. The wax ink 2a in a softening state by heating of a thermal head 6 is transferred to a transfer roller 7. However, since the wax is in a comparatively low pressure-contact state, it is not transferred to the transfer roller 7 excepting that it is ready for printing, even when it is in a softening state. The unevenness of paper 8 is smoothed by a thermal pressure roller 9. In addition, the paper is heated and given a sufficient pressure by equal peripheral speed of both rollers. The rotating load is small, and the wax ink 2d to be transferred to paper is transferred to paper due to the application of ample heat and pressure to the transfer portion of the paper.

Filed: 1996-10-08
Abstract: PROBLEM TO BE SOLVED: To provide a small and low cost optical pickup with a simple structure usable for the reproduction of both DVD(digital video disk) and CD(compact disk) with one lens. SOLUTION: When the DVD 20D is reproduced, a laser beam is made stronger like as (A) in the figure. The transmitting area on a light control plate 16 is widened, and the substantial numerical aperture NA of an objective lens 18 is increased, then the opening part PA having the transmittance of higher than 50% becomes like as (B) in the same figure. When the CD 20C is reproduced, the laser beam is weakened like as (C). The transmitting area of the light control plate 16 is narrowed, and the substantial opening rate of the objective lens 18 is decreased, then the opening part becomes PB narrower than PA like as (D) in the same figure. The laser beam is passed through only around a center of the objective lens 18. Thus, the beam is focused on the information recording surface for any of the CD or DVD.
