Title: Deviation direction discrimination circuit for positioning system using incremental encoder
Inventor: MARUSHIMA KUNIYOSHI
IPC: G05D3/12
Filed: 1988-10-14
Abstract: PURPOSE:To obtain a deviation direction discrimination signal directly from the output of a counting circuit by providing a gate circuit and an RS flip-flop circuit and using the output of the RS flip-flop circuit as the deviation direction discrimination signal. CONSTITUTION:For example, the output of a digital counting circuit DC varies from N-1 to '0', the MOSB signal (b) varies from LOW to HIGH and only when the output is '0', a Z signal (c) goes down to LOW. In this case, the output of a NAND gate circuit which inputs the MSB signal (b) and Z signal varies from HIGHT to LOW when the output of the digital counting circuit DC varies from '0' to '1'. Further, the output (e) of the RS flip-flop circuit FF which inputs the MSB signal (b), the output (d) of the NAND gate circuit, an R input signal, and an S input signal has hysteresis characteristics. Consequently, the deviation direction discrimination signal is obtained directly from the output of the counting circuit DC.

Title: Digital type protective relay
Inventor: IGUCHI KENJI
IPC: H02H3/46
Filed: 1990-09-26
Abstract: PURPOSE:To see that operation errors do not occur even during the ripple of generator output frequency by equipping it with an SSG, which detects the output frequency of a generator, and a frequency multiplier, which outputs the sampling pulses of that multiplied frequency. CONSTITUTION:The output pulses of an SSG 3 are input to a counter 4, which constitutes a frequency multiplier, and in the counter 4 is input a reference clock of 500KHz. When the output pulses of the SSG 3 are counted by the reference clock, data '10000' are gotten from 500KHzdivided by 50Hz=10000, and the data are input into the dividing circuit 5 at the following stage, which constitutes a frequency demultiplier similarly. Since the reference clock of 60MHz is input in the dividing circuit 5, if it is divided by 10000 by the reference clock data '10000', it follows that 6MHzdivided by 10000=600Hz, and the diving circuit 5 outputs the pulses having the frequency of 600Hz.

Title: Wafer conveying mechanism
Inventor: NAKATANI KENJI
IPC: B65H5/06
Filed: 1986-10-30
Abstract: PURPOSE:To prevent dust or the like from sticking to the backside of a wafer as well as to keep off any drop in yield of a product obtainable from top of the water in the after-process, by pivotally supporting a set of large diametral rollers, supporting the wafer and giving feed to it, on a turning shaft parallelly. CONSTITUTION:When a wafer is supported by large diametral rollers 5c and 4c at the rightmost end and rollers 5b and 4b in front of them, each large diametral roller gives left feed to the wafer as rotating and the wafer is supported by the large diametral roller one after another, giving the feed force to each, conveying it in succession. Accordingly, such one that comes into contact with the backside of the wafer is the large diametral roller made of fluorocarbon resin excellent in wear resistance such as Teflon or the like, so that occurrence of dust is held down to minimum, while a contact area to the wafer backside can be minimized. And, since it is of a roller contact type, any dust from a belt is not transferred to the wafer backside, thus any drop in yield of a product obtainable from top of the wafer by resticking or the like onto a surface of the wafer in the after-process is preventable.

Title: Method for welding contact point material
Inventor: KUBO MASAO
IPC: B23K26/00
Filed: 1988-10-14
Abstract: PURPOSE:To obtain welding in a deeply penetrated state with high reliability by arranging a contact point material slantingly with one end thereof in contact with a metallic sheet and irradiating a gap formed on the other end thereof with a laser beam. CONSTITUTION:The contact point material 1 is arranged slantingly so that an angle formed between the contact point material 1 made of Ag, etc., and the metallic sheet 2 such as a Cu sheet is made to <=about 30 deg.. The one end 1a side of the contact point material 1 is brought into contact with the metallic sheet 2 and the other end 1b side thereof is opened to form the gap 3. The gap 4 is irradiated with the laser beam 4 from the horizontal direction. The laser beam 4 is confined in the gap 3 while repeating multiple reflection between the contact point material 1 and the metallic sheet 2. As a result, even if the contact point material 1 or the metallic sheet 2 has high reflectivity with respect to the laser beam 4, heat required for welding is applied thereto effectively. Accordingly, welding with deep penetration is obtained.

Title: Vehicular seat device
Inventor: EGAMI SHINKO
IPC: A47C7/46
Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To restrain the deterioration of a posture in sitting over a long time by detecting the posture variable of a sitting person, and rectifying the posture to a proper status whenever the variable exceeds the preset value. SOLUTION: A seat back 13 is fitted with a sensor for detecting the posture variable of a sitting person M and a valve 18 controls an air flow from a compressor 19 to an airbag 17, according to a valve control device 23 to determine the operation of the valve 18 depending on output from the sensor. When the sitting person M comes to have a stoop due to a long-time drive, his/her chest B tilts forward and the pelvis C turns back. At the same time, the deflection of the F part of the lumbar F becomes large. According to the change in bending of the F part of the lumber, the air is made to flow from the compressor 19 to the airbag 17. The internal pressure of the airbag 17 is thereby made to rise, and the airbag 17 increases a supporting force for the F part of the lumber F.  The deflection thereof is, therefore, gradually reduced and the posture of the sitting person M is fixed at an initial status. According to this construction, the posture of the sitting person M is kept within a proper range, thereby reducing his/her fatigue.

Title: Lighting device
Inventor: MARUYAMA TATSUO
IPC: F21V7/00
Filed: 1990-09-29
Abstract: PURPOSE:To obtain a lighting device which is miniaturized and whose output is heightened by forming reflecting films on the reflecting surface of a reflector made of resin and the bulb surface of a lamp disposed opposite to the reflector, and providing a translucent cover to an opening for projecting light. CONSTITUTION:Only the infrared component of light emitted from a filament 9 at the lighting of a lamp 4 is reflected by a reflecting film 5 and allowed to return to the filament 9. Visible light and the remaining infrared component which has not been removed are transmitted through the reflecting film 5 and emitted outside of a bulb. Infrared radiation is further removed by a reflecting film 3 from the component of the light directed onto a reflector 1. Most part of infrared radiation is thus eliminated with little infrared radiation included in the light which is not allowed to pass through the reflector 1 but is directed onto a translucent cover 6. Overheating of the reflector 1 and the translucent cover 6 is thereby restrained, achieving the miniaturization and high output of the device.
