Title: Automatic centering method for wafer protective tape
Inventor: SHINOHARA MASATOSHI
IPC: H01L21/68
Filed: 1990-08-17
Abstract: PURPOSE:To prevent the protective tape at a peripheral edge from protruding due to eccentricity when the protective tape having nearly the same size as that of a wafer is pasted by a method wherein an eccentricity amount with reference to a reference length and an eccentricity amount from a reference line are computed by using a microcomputer from the distance between detections by means of a position detection sensor. CONSTITUTION:The winding amount of a conveyance tape 3 is advanced by a distance of P+ X from a distance of S by using detection sensors 5A, 5B; the tape is once stopped. On the other hand, while a grit 7 as one example of a suction body of a wafer 1 is being advanced by a distance of L to its negative direction, it corrects + or - Y and is stopped. Then, the grit is situated on the same core as that of a protective tape 2 on the conveyance tape 3. While a suction force is being made to act, the conveyance tape 3 and the suction grit 7 are moved to the positive direction at the same speed. Then, the protective tape 2 is stripped from the conveyance tape 3. When the suction grit 7 corrects + or - Y and is stopped at the distance of L, it is returned to its original position. Thereby, the pasting operation of a wafer 1 and the protective tape 2 is started on the same core.

Title: Focal point detecting device
Inventor: SUDA YASUO
IPC: G02B7/34
Filed: 1984-10-17
Abstract: PURPOSE:To make highly accurate focal point detection, by setting each element so that the length in the shorter side direction of the image of the visual field mask of a focal point detecting device using an image re-forming system can be made longer than the length in the shorter side direction of a photoelectrically converting element row. CONSTITUTION:A diaphragm 5 has two openings 5a and 5b and the luminous flux made incident on the opening 5a is passed through the 1st inclined section 2a of an image separating prism 4. The luminous flux made incident on the opening 5b is passed through the 2nd inclined section 2b of the prism 4. An image re-forming lens 6 forms images 7a and 7b of a visual field mask 2 on photoelectric conversion element trains 8a and 8b and, since the image separating prism 4 is provided in the optical path, the images 7a and 7b of the visual field mask 2 are separated into two in the upward-downward direction. The photoelectric conversion element trains 8a and 8b are constituted by arranging photoreceptor, each of which is composed of about 10 picture elements, and convert the luminance distribution of an object into electric signals. Since the diaphragm 5 is projected to the vicinity of the exit pupil face of a photographing lens 1 by means of a field lens 3, the images 7a and 7b of the mask 2 never produce vignetting of lens caused by the photographing lens 1.

Title: Controller for stepping motor
Inventor: OKUCHI HIROAKI
IPC: B60Q1/076
Filed: 1996-08-20
Abstract: PROBLEM TO BE SOLVED: To surely correct the positional deviation of a rotor immediately before the driving of a stepping motor is started by predicting the next driving starting timing of the motor and preexciting the coil of the same phase as the last excitation phase at the preceding driving time within a prescribed period of time before the predicted next driving starting timing. SOLUTION: The control circuit 16 of a stepping motor 24 functions as a driving starting timing predicting means which automatically predicts the next driving starting timing of the motor 24 by calculating a target number of driving steps within a prescribed period of time. The circuit 16 drives the motor 24 to a target position by outputting a drive signal based on the computed result of the target number of driving steps. While the motor 24 is stopped, in addition, the circuit 16 stops the power supply to the motor 24 and, at the same time, corrects the deviation of the stopping position of the rotor of the motor 24 immediately before the driving of the motor 24 is started by preexciting the coil of the same phase as the last excitation phase at the preceding driving time with a prescribed period of time before the predicted next driving starting timing. Therefore, the rotation of the motor 24 can be controlled accurately.

IPC: H04N5/445
Filed: 1984-10-18
Abstract: PURPOSE:To recognize easily timer execution contents and timer reservation contents by displaying timer reservation contents on CRT surface immediately after or before the timer reservation execution. CONSTITUTION:Timer reservation contents are checked in accordance with program data written in the ROM of a control circuit 20. The presence or absence of the on-time arrival is checked in case of on-reservation, and the power source of a television receiver is turned on at the on-time. Simultaneously the processing for executing the on-reservation is started, and the television picture of the reserved channel is projected on a CRT surface 5. Then checking is made whether or not the prescribed period expires after channel reservation display. A channel reservation picture keeps on displaying on the CRT surface until the prescribed period expires. For instance, after 5sec expire, the television picture of the reserved channel is displayed instead of the channel reservation picture.

Title: Heating device for semiconductor
Inventor: SAIJO YOSHIAKI
IPC: H01L21/56
Filed: 1986-09-19
Abstract: PURPOSE:To realize the change in a heating condition according to the state of an object to be heated and according to its accommodated location by a method wherein, at a heating device for a semiconductor, a region to accommodate the object to be heated is installed in a story-like structure inside a heating chamber so that a circulating path can be formed around this heating chamber made of metal. CONSTITUTION:If an 'array of lead frames' 8 is accommodated in a region 3 installed in a story-like structure, the information on its location or the like is input to a control device 15 by an input device 16. On the basis of this information, a heater 10 and a blower 11 are driven. If a laminar hot blast is fed in a predetermined direction, the rate of the rise in temperature at the 'array of lead frames' 8 becomes slow at the downwind side. Therefore the sense of rotation of the blower is switched at regular intervals so that the direction of an air blast can be reversed. In addition, even when a new object to be heated is accommodated after completion of the heating operation of the 'array of lead frames' in one region 3 installed in a story-like structure, a low-temperature hot blast is not fed to the other region 3 where the temperature is kept constant by each circulation path. Therefore, it is possible to prevent the drop in temperature and to keep the temperature constant.

Title: Magnetic recording and reproducing device
Inventor: TOURIYUU KOUJI
IPC: G11B5/41
Filed: 1991-08-30
Abstract: PURPOSE:To prevent the deposition and adhesion of dust on the contact surface of a magnetic recording and reproducing element by providing a cleaning means which cleans the magnetic medium sliding surface of the element integrally with the element. CONSTITUTION:The surface S of a magnetic recording and reproducing element 5a which slides on a magnetic medium M is cleaned by reversely rotating a cleaning means A in an interlocking way when the running direction of the medium M is reversed. As a result, the deposition and adhesion of dust on the sliding surface S of the element 5A caused by the frictional heat of the medium M produced when the element 5A slides on the medium M can be prevented and the sliding surface S is always maintained in a clean state, because the sliding surface S is cleaned whenever the running direction of the medium M is reversed. Therefore, recording and reproduction of information can be performed normally for a long period even when no special cleaning is made.
