Title: Thin film inspecting device
Inventor: SUGIYAMA SACHIHIRO
IPC: G01B11/06
Filed: 1987-11-30
Abstract: PURPOSE:To uniformize the angles of incidence on and reflection from a body to be inspected and to perform thin-film inspection with high accuracy by generating light emitted by a light source to uniform intensity, and converging and guiding only the parallel component of the reflected light from the body to be inspected. CONSTITUTION:The light emitted by the light source 10 is diffused uniformly by a diffusion plate 13 and reflected by a half-mirror 14 to illuminate the surface of a wafer 1 vertically. The reflected light from the wafer 1 passes through a mirror 14 and only parallel light on the wafer 1 is converged by a condenser lens 15. Then only single-wavelength light is selected through an interference filter 16 and electrode into an image pickup device 17. Then the light intensity is detected as to respective parts of the wafer 1 from the picked-up image data to measure the thickness, etc., of a film. Thus, the angle of the light incident on the wafer 1 is equal at the respective parts and the light propagation distance in the thin film becomes equal, so the same interference conditions are set at the respective parts. A thin film of resist formed on the wafer 1 is inspected with high accuracy.

Title: Image forming device
Inventor: FUSHIMI SEIICHIRO
IPC: G03G15/08
Filed: 1987-11-30
Abstract: PURPOSE:To drive to rotate a detection probe with the rotation of a photosensitive drum and to quickly and accurately detect the density of toner by providing the detection probe on a specified position. CONSTITUTION:The detection probe 45 obtained by integrally molding a power supply part 70 with a detection part 71 is fitted out of the image forming area of the photosensitive drum 21. And the toner supplied to the drum 21 is made to adhere to the detection part 71. Then a light beam from a light emission diode is radiated onto the detection part 71 and the reflected light is received by a photodiode so as to detect the density of the toner by converting the variation of a light receiving quantity into a voltage. Thus it is unnecessary to turnably mount the probe 45 and a special driving mechanism is not necessitated. Since the probe 45 is provided on the end part of the drum 21 opposite to the toner replenishing port of a developing unit 56, toner detecting speed becomes high and the detection becomes accurate.

Title: Semiconductor element mounting device and method thereof
Inventor: KOGA YASUTAKA
IPC: H01L21/60
Filed: 1993-12-02
Abstract: PURPOSE:To accurately mount a semiconductor chip without extra bonding by a method wherein the chucking force of the semiconductor chip is controlled by bonding tool before the press of the semiconductor chip is finished based on the pressing force detection signal by the bonding tool. CONSTITUTION:When a bonding tool 21 lowers, the electrode-formed surface of a semiconductor chip 5 is pressed to a printed board 1 through the intermediately of an anisotropic conductive film, and the pressing force of the bonding tool 21, which is detected by a pressing force sensor 30, begins to increase. When the pressing force of the bonding tool 21 reaches the first pressing force P1=3kg, the operation of an evacuating device 24 is stopped by a control part 32. As a result, the chucking strength of the semiconductor chip 5 by the bonding tool 21 is released, and the semiconductor chip 5 can be moved in the lateral direction with respect to the bonding tool 21. Consequently, the semiconductor chip can be mounted in a precise manner without extra bonding.

Title: Modulation wave frequency measuring method
Inventor: SAITO SHIGEKI
IPC: H04L27/227
Filed: 1989-11-20
Abstract: PURPOSE:To unnecessitate setting of preamble and to improve the transmission efficiency by measuring a frequency of a modulation wave while a clock recovery preamble is sent and converting the frequency into a frequency of a reference signal. CONSTITUTION:A timer 26 of a gate signal generating circuit 25 and a timer clock 27 are used to generate a gate signal in response to a time equivalent to an integral number of multiple of the period of the symbol in the frequency measurement of a modulation wave and a counter 23 counts edges of the modulation wave by a gate time represented by a gate signal. Thus, the average frequency of the modulation wave measured in this way is converted into a data representing the frequency of the reference signal by a reference signal conversion circuit 29. Thus, the frequency of the reference signal is obtained from the clock recovery preamble. The preamble signal provided separately is not required to measure the frequency of the reference signal.

Abstract: PURPOSE:To improve the yield by a method wherein a laser generator, a reflective laser detector, a processor and an air pressure controller are provided for alignment and exposure. CONSTITUTION:A laser beam 10 is applied and a reflected light is detected by a detector 12 and positions of alignment marks A1-A4 and B1-B4 in a one- shot region 20 are obtained and X-Y direction distances between the alignment marks A1 and A3, A2 and A4, B1 and B2 and B3 and B4 are obtained by a processor 13. A pattern discrepancy, i.e., the variation of the contraction factor of a contraction lens 3, in the one-shot region can be detected by comparing the obtained distances with a reference value. The output of the processor 13 is inputted to an air pressure controller 15 to control enclosed gas in a regulating part 4 and the contraction factor of the lens 13 is corrected. With this constitution, when a device pattern is aligned with a wafer and a reticle, the pattern discrepancy in the one-shot region can be reduced.

Title: Operation detecting device
Inventor: YAMASHITA KENICHI
IPC: H01H35/14
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To surely detect operation regardless of the magnitudes of vibration, inclination, and reaction by providing two or more conductors on the internal wall of a case, and causing the conductors to be short-circuited or opened by means of a moving object. SOLUTION: A case 4 is covered on its inside with a film substrate 1, and a first contact 2 is provided in the form of a fence on the circular part of the substrate which corresponds to the upper surface of the case. A second contact 3 is provided in the form of a fence on the circular part of the film substrate which corresponds to the lower surface of the case. By means of vibration, inclination, and reaction caused during the operation of a subject whose operation is to be detected, a conductive sphere 5 is moved and becomes conducting on contact with the contacts 2, 3; when not in contact with the contacts 2, 3, the sphere 5 becomes nonconducting. By detecting these conducting and nonconducting states using an external device, whether or not the subject whose operation is to be detected is operating can be determined.  When an operation detecting switch is inclined, for example, since the contacts 2, 3 are arranged alternately also in the circumferential direction the sphere 5 is moved horizontally by the horizontal movement of the subject whose operation is to be detected, and repeats moving into and out of contact with the contacts 2, 3.

Title: Method for discriminating disk size
Inventor: SHIMIZUME KAZUTOSHI
IPC: G11B19/12
Filed: 1994-12-08
Abstract: PURPOSE: To discriminate the disk size without erroneous discrimination by generating kick pulses for a specified period of time when a reference speed is attained after rapid increasing of the rotating speed of a spindle motor by the kick pulses and making decision in accordance with the measurement time until the reference speed is attained. CONSTITUTION: The kick pulses are supplied from a pulse generator 57 via a system controller 20 of a spindle servo circuit and the rotating speed of the spindle motor 2 increases sharply when a play key of the disk player is operated. Servo control by a rough servo circuit 30 is executed and the frequencies and phases of a clock WJCK based on a reproduced synchronizing signal and reference clock RFCK coincide and a GFS signal from a phase difference measuring section 41 turns to an H. The kick pulses are again supplied for the prescribed period of time and the time until the reference speed is attained again is measured by the controller 20 when the motor 2 reaches the reference speed. The disk size is decided by the result of this measurement.  The discrimination without the erroneous discrimination is thus executed as there is much influence of the mass, such as dust, without setting the kick time for long.
