Title: Damage detecting device for cutting tool employing ae wave
Inventor: NAKAGAMI RYUZO
IPC: B23Q17/09
Filed: 1987-09-26
Abstract: PURPOSE:To remove the noise signal component of a main shaft system and to prevent the occurrence of erroneous detection, by a method wherein a differential circuit is situated between an average value detector, effecting average value detection on 8 signal from an AE conversion element, and a comparing circuit, comparing an average-value-detected signal with a threshold. CONSTITUTION:An AE signal from an AE conversion element 10, detecting damage of a cutting tool by means of an acoustic emission wave, passes a preamplifier 11 and an average vale detector 12 to effect average value detection thereon. The d.c. component of noise. e.g. friction noise of a bearing due to rotation of a main shaft, and impact noise of a main shaft transmission gear, is removed by means of a differential circuit 14 formed with a CR circuit. An average-value-detected signal is compared with a threshold, preset by a variable resistor VR, by means of a comparator 13, and when it exceeds the threshold, a flip flop circuit 15 is set to output an alarm. This constitution enables high-precise detection of an AE signal during damage of a tool irrespective of a fluctuation in the number of revolutions of a main shaft, and permits prevention of the occurrence of erroneous detection and a trouble occasioned thereby.

Title: Temperature control device for heat roller
Inventor: KUSUMOTO KEIJI
IPC: G03G15/20
Filed: 1985-10-29
Abstract: PURPOSE:To prevent temperature to be controlled from being dropped from an target value by increasing the level of a set temperature and increasing the heat value of a heater when the temperature difference between the surface of a heat roller and a portion near a pyroelectric sensor. CONSTITUTION:The electric output of a pyroelectric infrared-ray sensor 23 arranged near the heat roller 4 is outputted to an input terminal ANo of an one-chip microcomputer 40 through a circuit 36 in a processing circuit 35. On the other hand, the output of a reference diode sensor 25 arranged near the roller 4 is sent from a circuit 38 in the circuit 35 to an input terminal AN1 of the computer 40 through a chopper 29. Both the signals are synthesized by a detecting signal synthesizing part. A set signal generating part generates an electric signal with a level corresponding to the surface temperature of the roller 4 to compare the output with the synthesized signal. Current supply to a heater 5 stored in the roller 4 is controlled on the basis of the output of a comparison control part in accordance with compared result.

Title: Insert
Inventor: YAMADA HIROSHI
IPC: H05K7/14
Filed: 1993-09-29
Abstract: PURPOSE:To remarkably reduce time for decomposition and assort by providing a ring which has spring-like extention/contraction performance, enlarging the ring part while screwing a screw, and contracting the ring while removing the screw. CONSTITUTION:A ring 7 is provide on an outer side of a cylindrical insert 4. The ring 7 bites into a boss 3 by inserting the insert 4 into the boss 3, and screwing a screw 6 thereinto. Then the insert 4 is fixed to the boss 3. The insert 4 recovers its measurement and shape of the state at the time of insertion by contraction force of the ring 7, and is removed easily. At the time of decomposing electronic equipment, the insert installed on a plastic case is easily demounted by removing the screw. It is thus possible to remarkably reduce decomposition and assort time, and promote recycling.

Title: Multiplexer with wavelength selectivity for optically adding and eliminating without loss
Inventor: FATEHI MOHAMMAD T
IPC: H04B10/29
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To eliminate a passage loss due to the addition or elimination of wavelength, by optically exciting a fiber amplifier that is subjected to doping treatment by rate earth elements. SOLUTION: A wavelength division multiplexing signal is fed as an input to an optical circulator 310. When it exits the light circulator 310, it is amplified by an optical fiber segment 340 that is subjected to doping treatment by erbium before reaching a Bragg lattice 330. The Bragg lattice 330 is adapted to reflect and return the subset of a light signal with a selective wavelength toward the optical circulator 310. These reflected signals are eliminated, subjected to multiplex separation, or divided as needed. In this configuration, an excitation source 360 is coupled to an area between the optical fiber segment 340 and an output port 312 of the light circular 310, thus exciting the optical fiber segment 340 so that an erbium ion reaches a high meta-stable energy state.

Title: Surface type light source device and its manufacture
Inventor: TOYODA KOICHI
IPC: F21V8/00
Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To obtain high luminance and decrease the number of components as to the surface type light source device which is constituted by making a linear fluorescent lamp abut against an end surface of a transparent resin plate body and providing a reflecting layer containing a light diffusing and reflecting material partially on the reverse surface of the transparent resin plate body. SOLUTION: When a scatter pattern 3 is formed by covering the reverse surface 2 of a light guide plate 1 made of a light-transmissive material with a light diffusive material 17, the film thickness of the coating is increased in proportion to the distance from the fluorescent lamp 8 as a light source. Consequently, high luminance can be obtained without lowering the transmissivity of the diffusion plate 6 since no light beam is projecting from the light guide plate 1 because of diffuse reflection or without lowering the transmissivity by increasing the number of elements of the diffusion plates 6, so that the surface type light source device which has high efficiency, low cost, and handling improved can be obtained.

Title: Wire bonding device
Inventor: SHIMIZU NAGAO
IPC: H01L21/60
Filed: 1989-09-19
Abstract: PURPOSE:To obtain a wire bonding device capable of obtaining time required for bonding within a specified time even if the number of bonding is increased by detecting the end of bonding for each bonding head section and laying out a synchronizing device which synchronizes a motion up to bonding. CONSTITUTION:Bonding head sections 13a and 13b transmit end information to a synchronizing device 14 at the time when each bonding operation is finished. The synchronizing device 14 controls the end information of every bonding head section 13 and transmits carrier start information to an outside circuit board carrier device 3 at the time when the device 14 has received every end information. Based on the above performance, the outside circuit board carrier device 3 can start the carrier of an outside circuit 5 in automatic mode at proper timing irrespective of the number of wire bonding or the classification method for a region. It is, therefore, possible to carry out bonding in 1/2 time compared with the prior art method, if the number of wire bonding is the same, by laying out two bonding head sections 13 as described above.

IPC: F25B13/00
Filed: 1994-09-12

Title: Optical rotation angle detector
Inventor: SUZUKI HIROYOSHI
IPC: G01D5/26
Filed: 1991-09-24
Abstract: PURPOSE:To accurately detect a rotation angle of a rotation axis by converting light emitted from a light source toward the rotation axis into a parallel flux and condensing it onto a position detecting element after deflecting it by a 180-degree deflecting means which rotates integrally with the rotation axis. CONSTITUTION:Light emitted from a light source 3 passes through a collimator lens 4 and an aperture member 5 to produce a parallel flux of predetermined diameter, which is incident to a prism lens 6 fixed on a rotating member 7. The incident light is reflected on a first reflecting surface 61 and a second reflecting surface 62, and after being deflected by 180 degrees in total, the light is condensed into a spot light on a light receiving surface of a light position sensing element 8 by a condenser lens part 63. When a rotation axis 2 is rotated, the spot light moves on the light receiving surface of the element 8, so that a light incident position of the element 8 is equal to a rotation angle of the member 7, that is, the axis 2, and the current output is led by a detecting circuit 10 thereby providing a rotation angle output corresponding to the light incident position. Thus highly accurate rotation angle detection is possible for a long term.
