Title: Method for accommodating optical fiber
Inventor: IKEDA MIKIKO
IPC: G02B6/00
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To decrease the area necessary for optical components along with reduction of an optical fiber accommodation area by making an optical fiber move in any direction and avoiding the stress concentration on the optical fiber. SOLUTION: A laterally movable mechanism component 2 is installed on an optical fiber led-out port 4. An optical fiber 1 inside a case 3 moves so as to follow the movement of this mechanism component 2. Stresses are not applied from the surroundings to the optical fiber inside the case even if the case 3 moves, because the optical fiber 1 has a sufficient looseness inside the case 3. The movable area of the mechanism component 2 is set to laterally open at up to 90 degrees so that the optical fiber 1 is not caught in the case 3.

Title: Radio call system
Inventor: OSANO TSUNEO
IPC: H04W84/08
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To improve the transmission efficiency of a radio call system. SOLUTION: When each calling device receives a common polling command that is issued from a center unit (step 101), it supervises whether a calling device whose order 1 to m-1 is earlier than the response order m of its own device that is preliminarily assigned already responds (step 103 to 107) and returns response from its own device to the center unit (step 108). Furthermore, the center unit sets a response order only to an operating calling device and notifies this of each calling device. Thereby, only issuing a common polling command one time makes it possible that is efficiently communicates with a call and response from/to plural calling devices which operate.

IPC: G01F11/06
Filed: 1989-12-26
Abstract: PURPOSE:To discharge fluid effectively, repeatedly, and quantitatively by providing a fluid supply means which supplies simultaneously the fluid having the same pressure to a 1st and a 2nd flow passage and a selector valve mechanism which switches and communicates the 2nd flow passage and a discharge port on a 2nd cylinder internal chamber.

The inside of the internal chamber 1b is shielded from the high pressure in a communication pipe 9 and opened (reduced) to an atmosphere. At this time, the high pressure in a chemical supply path operates on the inside of a 1st cylinder internal chamber 1a, so the pressure in the internal chamber 1b becomes lower than the pressure in the internal chamber 1a and a piston 3 moves toward the internal chamber 1b with the pressure difference to send chemicals in the internal chamber 1b from the outlet 2c.

Title: Steel plate for painting and method for evaluating the steel plate
Inventor: INOUE MASATAKA
IPC: G01B21/30
Filed: 1989-12-28
Abstract: PURPOSE:To improve the painted sharpness of a steel plate for painting and press moldability by setting the coefficeint KS of the steel plate for painting which is expressed with a specified expression at a specified value or more. CONSTITUTION:The surface of a sample 40 is scanned with a probe 10. The random waveform corresponding to the roughness of the irregularities of the surface is outputted. The ramdom waveform is inputted into a three-dimensional surface-shape measuring device 3 and converted into a voltage signal. Then, the input signal undergoes Fourier transformation in frequency analyzing device 4. The signal is decomposed into amplitude levels for individual frequencies. Thus frequency analyzing curves are plotted. Then, a wavelength region which blocks the painted sharpness is set within a wavelength range of 1.0 - 6.0 mm on the frequency analyzing curve with a microcomputer 5. A wavelength region for improving press moldability is set within a wavelength region of 0 - 1.0 mm on the frequency analyzing curve. Then, power spectrum sums PA and PB of the wavelength region which blocks the painted sharpness and the wavelength region for improving the press moldability are obtained. The power spectrum sums PA and PB are used, and the coefficient KS of the steel plate for painting is obtained by the expression KS = (PA + PB)/PA. Thus, the painted sharpness of the steel plate for painting and the press moldability can be improved.

IPC: H02P25/06
Filed: 1999-11-30
Abstract: PROBLEM TO BE SOLVED: To prevent overshoot or the like and perform excellent control in quick response by effectively using a control system showing the conventional stable control characteristic. SOLUTION: A control device of an LSM type vehicle is constituted by containing a speed controller. In the controller, when it is decided that a calculated current value is in the outside of an allowable range in the last timing (NO in S200), whether the velocity deviation in the current timing is closer to zero as compared with the last timing and is satisfying the condition that the velocity deviation is in a specified range or not is decided (S210, S211). In case the above condition is not satisfied, a processing is executed in which the value eliminating a proportional term of the velocity deviation from an integrated value (called an immediately preceding integrated value) just before the calculated current value is in the outside of the allowable range is used as an integrated value Yn in obtaining the calculated current value (S214).  When the above condition is satisfied, a process (S213) that the preceding integrated value is used as the above integrated value Yn is repeated until velocity deviation becomes practically zero.
