Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To manufacture a wire with proof load. SOLUTION: A proof tension control mechanism 30 is provided in a wire passage between a wire-drawing mill 20 and a winding bobbin 50. The proof tension control mechanism 30 includes dancer mechanism 15 and a tension detector 16. On the wire w, tensile load (e.g. 120% or higher) larger than an estimated load expected applied by the wire saw is applied by the proof tension control mechanism 30 before the wire is taken up by the winding bobbin 50. It is guaranteed that the wire w wound on the winding bobbin 50 is not cut under the estimated load along its overall length. Reliability is further enhanced if the test is conducted while applying bending stress in addition to the tensile stress.

Title: Air flowmeter
Inventor: KOBAYASHI CHIHIRO
IPC: G01F1/68
Filed: 1990-11-30
Abstract: PURPOSE:To prevent influences of a divagation by controlling the ventilation resistance of a rectifier grating, and making constant the flow velocity of a measuring part in accordance with the pattern of the sneaking divagation. CONSTITUTION:A rectifier grating 12 bordered by a holding frame is rigidly held by a grating fixing member at an entrance where a suction air enters the body of the flowmeter. The grating is fine over an entrance 15 of a bypass, so that the ventilation resistance becomes large and the flow velocity is decreased. On the other hand, the grating 12 becomes coarse at the opposite side of the entrance 15, and therefore the ventilation resistance is small and the flow velocity is consequently increased. When a divagation pattern 17 which flows fast over the entrance 15 and slowly at the opposite side enters the body through a suction air duct 13, the flow velocity of the air entering the entrance 15 becomes generally uniform. Accordingly, even if the distribution of the flow rate after the air passes thought the grating 12 is not uniform, since the ventilation resistance over the entrance 15 is controlled so as to achieve the same flow velocity at the same flow rate, the influences of the divagation can be prevented.

Title: Electrode-less discharge lamp
Inventor: UKEKAWA MAKOTO
IPC: F21S2/00
Filed: 1991-12-13
Abstract: PURPOSE:To provide an electrode-less discharge lamp which can be easily started using a small-sized high frequency power source. CONSTITUTION:An induction coil 2 is wound around a cylindrical bulb 1 made of a light transmission material. The bulb 1 is formed, at its bottom surface, with a recess portion 1a in which a preliminary discharge coil 3 is disposed. When a high frequency current is supplied to the preliminary discharge coil 3, a small-diameter annulus like configuration discharge occurs, as a preliminary discharge, owing to a high frequency field formed around the preliminary discharge coil 3. If, thereafter, a high frequency current is caused to pass through the induction coil 2, annular discharge occurs due to the high frequency field formed around the induction coil 2. By this annular discharge, a discharge gas sealed in the bulb 1 is excited to fluoresce. Since the annular discharge occurring from the preliminary discharge coil 3 is small in diameter, starting becomes easy.

Title: System and method for reproducing continuous media streams
Inventor: HO TOMOO
IPC: H04N21/44
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive and simple system capable of reducing degradation in the quality of continuous media streams to be reproduced even when the load of a transmission line gets light or heavy by successively reading and reproducing the contents of continuous media streams stored in a buffer part through a reproducing part. SOLUTION: The contents of continuous media streams received through an I/F part 110 are stored in a buffer part 130. A reproducing part 150 successively reads and reproduces the contents of continuous media streams stored in the buffer part 130. Then, non-reproduced contents stored on a disk part 140 are read out, written in an 'empty buffer' and reproduced. Thus, the reproduction of streams can be immediately restarted and in spite of whether the load of internet is light or heavy, the degradation in the quality of reproduced media streams caused by instability on the transmission line of internet can be reduced.

Title: Cpu device containing plural memory elements
Inventor: OKAMURA NAOYA
IPC: G03G15/00
Filed: 1989-12-19
Abstract: PURPOSE:To prevent such a case where a CPU runs away with abnormality of a certain memory element and damages other memory elements by storing previously a prescribed instruction to the head address of each memory element. CONSTITUTION:A program is described to each memory element of a ROM 2 and a RAM except a ROM 1 serving as a memory element including a program start address at and after the head address of each memory element. When the ROM 1 has no operation at all, the program is carried out at the head address of the ROM 2 while passing through the address of the ROM 1. In this case, the program run is stopped at the head address of the ROM 2 where a program is already described. Thus no damage is given to the RAM nor a system. An exactly same operation is carried out even with no actuation of the ROM 2. Thus it is possible to reduce the probability to rewrite other memories or to damage the system.

Inventor: NAKAI SATOSHI
IPC: H05B6/68
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To accurately control a quantity of a microwave, and perform proper cooking by actuating a timer by detecting a start of oscillation of a magnetron, and impressing the microwave for a fixed time by this timer. SOLUTION: An actuating part 12 of a timer to control a start of a count of a timer 11 to turn off a timer switch 10, is provided. The actuating part 12 starts a count by actuating the timer 11 by generating, for example, a trigger pulse by information from an oscillation detector 4 to detect a start of oscillation of a magnetron. Therefore, time counted by the timer 11 is time after the magnetron starts oscillation, and microwave impressing time is accurately set. In an electromagnetic switch 15b, since a cooking switch 17 is normally a temporary contact type switch, a closed circuit of an exciting coil 15a is formed so that an electromagnetic switch 15 can maintain an on-condition even if the switch 17 separates.

Title: Optical head positioning device for optical disk driver
Inventor: OKAYA HIDEKI
IPC: G11B7/085
Filed: 1991-12-13
Abstract: PURPOSE:To provide an optical head positioning device for an optical disk driver which can accurately position an optical head at a target track at a high speed. CONSTITUTION:An optical head positioning device for an optical disk driver contains a linear motor 8 which moves the mobile part of an optical head 5 into the radial direction of an optical disk 4. The motor 8 is provided with a linear scale 16 which has a pitch equal to the track pitch of the disk 4 or a pitch equal to a fraction of an-integer value of the track pitch. The head 5 moves with detection of the graduation of the scale 16 and therefore does not need to detect the track information out of a pre-group of the disk 4. Thus the head 5 can move at a high speed. Therefore the positioning time of the head 5 is shortened and a high speed seeking operation is attained.
