Title: Clean room
Inventor: MATSUO TAKENOBU
IPC: F24F7/06
Filed: 1989-12-27
Abstract: PURPOSE:To exclude the influence of a contamination source in a room by installing a partitioning wall which generates little dusts and is electric- conduction-treated, between the high and low clean regions in a clean room and preventing the influence of the clean gas stream which is disturbed on a working region side from exerting directly to the high clean region. CONSTITUTION:A partitioning wall 22 consisting of the wall member 24 of a transparent member which generates little dusts whose surface is electric- conduction-treated is installed between a high clean region H and a low clean region J in a clean room 10 so as to surround the transport passage of a transport device 14. The partitioning wall 22 is set in parallel to the flowing direction of a downflow (a) due to clean gas and at a height at least of a contamination source in transfer. During an operator I monitors the transport state of a wafer port 12 and the operation state of a thermally processing furnace 11, the exertion of the influence of the gas stream of the clean gas which is disturbed in a working region G by an operator I directly to a high clean region H is reduced. Accordingly, the influence of the contamination source which transfers in a room can be excluded, and the air cleanliness which is set can be maintained in a stable manner.

Title: Matched filter and large scale integrated circuit and communication system using the same
Inventor: TOYOYAMA SHINJI
IPC: H04B1/7093
Filed: 1999-11-30
Abstract: PROBLEM TO BE SOLVED: To provide a matched filter that can suppress an increase in the circuit scale even when the number of codes is increased by decreasing the circuit scale of a correlation arithmetic circuit and suppressing a signal change in a delay sequence. SOLUTION: This matched filter is provided with circuits 9, 11 that calculate exclusive OR of two input data and with circuits 17-20 that calculate the exclusive OR of two codes respectively corresponding to the two input data. Thus, the logic of correlation arithmetic circuits 13-16 is simplified compared with that of a conventional matched filter. Accordingly, 15 XORs and 5 selection circuits can configure the correlation arithmetic circuits 13-16 to decrease the circuit scale more in comparison with the conventional matched filter. Thus, even when the number of the codes is increased, the increase in the circuit scale can be suppressed.

Title: Image signal processing unit
Inventor: MIZUFUJI TARO
IPC: H04N5/232
Filed: 1994-12-28
Abstract: PURPOSE: To avoid mis-recognition of an object by detecting a moving object in image data based on number of picture elements in which a change in luminance of Y, R, B of image data and delayed image data is a threshold level or over in the automatic tracking of a video camera. CONSTITUTION: While the field angle of a television camera 1 is not changed, an input image signal S2 is A/D-converted, and a processing circuit 7 processes image data Y, R, B periodically and stores them to a memory 10. A characteristic picture element extract means of a tracking processing circuit 11 extracts picture elements in which a change in the luminance is a prescribed threshold level or over with respect to picture elements of optional characteristic luminance and chrominance information between the image data and image data delayed by a prescribed time. A moving body detection means of the tracking circuit 11 counts the number of extracted picture elements to detect a moving amount from the number of changed picture elements thereby detecting the moving body in the image data.  Thus, the moving body is detected based on luminance and chrominance information to avoid mis-recognition of the object in the case of automatic tracing.

Patent JP-H03130967-A (JP)
Title: Magnetic reproducing head amplifier
Inventor: IWAMURA SOICHI
IPC: G11B5/02
Filed: 1989-12-27
Abstract: PURPOSE:To make the output amplitude characteristic of a magnetic reproducing head amplifier smooth and a wide band by making a negative feedback circuit part where a negative feedback element is set as a resistance function simultaneously with a positive feedback circuit part where a positive feedback element is set as a capacitor. CONSTITUTION:The phase of a charging current IC1 flowing to ground stray capacity CS1 is the same as the current If8 of the positive feedback element C8. Therefore, only a differential current IS1 is supplied from a signal source 1 and the supply current is reduced. As the result, effective input capacitance is reduced and a resonance frequency can be shifted to the maximum of an FM carrier transmission band. Besides, the current If9 of the negative feedback element R9 damps the resonance characteristic of a resonance circuit formed by the capacity CS1 and the inductance of a magnetic head 1 and smooths the output amplitude characteristic. By making the negative feedback circuit function simultaneously with the positive feedback circuit in such a way, the resonance frequency is shifted and the head amplifier is stabilized in a wide band.

Title: Driving power source of capacitative element
Inventor: FUJITA YUJI
IPC: B06B1/06
Filed: 1991-12-24
Abstract: PURPOSE:To provide a miniaturized driving power source of a capacitative element with the power consumption lowered. CONSTITUTION:A DC voltage at about 12 Vdc is used as the input voltage Vcc. When a capacitative element 10 is charged, the primary side of a transformer T1 is turned on and off by an FET Q3, and a voltage generated on the secondary side is impressed on the element 10. When the element 10 is discharged, the secondary side of the transformer T1 is turned on and off by an FET Q4, the voltage generated on the primary side is returned to a charge recovering capacitor C1, and the electric charge is recovered. The FETs Q3 and Q4 are controlled by a control circuit 20 (IC), and a specified voltage is impressed on the element 10. Accordingly, since a single power source is used and the control circuit is furnished with one or two ICs, the driving power source is significantly miniaturized, and the power consumption is lowered since the charge is recovered and reutilized when the element is charged next time.

Title: Semiconductor laser and its manufacture
Inventor: FUJII HIROAKI
IPC: H01S5/00
Filed: 1993-12-10
Abstract: PURPOSE:To obtain a high-reliability semiconductor laser and a method for manufacturing it by relieving stress due to a deviation in composition ratio of a current block layer by a mesa. CONSTITUTION:This semiconductor laser has a double hetero structure machined from a clad layer 2 in a mesa stripe form and a current block layer 8 which selectively buries the mesa side face and the bottom face of this clad layer 2. A raw material gas used for selectively growing the current block layer 8 is mixed with a trace of HCl gas to accelerate the reevaporation of a raw material species on a selective mask. This relieves a deviation in composition ratio at an edge of a selective mask, thereby reducing the projection thickness of the current block layer in a mesa side face to a 10% or less of the thickness of the current block layer in a flat part.
