Title: Solid-state image pickup device
Inventor: IDE YUJI
IPC: H04N9/07
Filed: 1985-12-13
Abstract: PURPOSE:To suppress the generation of vertical moire by modulating the 1st color light by a spatial frequency of horizontal 2-picture-element period of a solid-state image pickup element, modulating the 2nd color light by a 4-picture- element period of spatial frequency and modulating the 2nd color light in opposite phase with the 2nd color light. CONSTITUTION:After an optical image incident via an image pickup lens 1 passes through an optical crystal filter 2 to reduce moire, the image is formed on the light receiving surface of an image pickup element 3 through a mosaic filter. An image pickup element 3 outputs the signal of each picture element by charge coupling transfer. For example, with the horizontal drive frequency of 4fsc (fsc is a chrominance subcarrier frequency) and horizontal picture elements and 500 vertical picture elements, the modulation component G is modulated by 2fsc and modulation components R, B are modulated by fsc. The moire for R, B components is caused at the locations of fH/2 and its multiple in horizontal direction and at the locations of fv and its multiple in vertical direction. Since the moire in the vertical direction is less, it is not required to locate an optical crystal filter in the vertical direction and the picture with less moire is obtained without decreasing the vertical resolution.

IPC: H04B1/7087
Filed: 1996-10-23
Abstract: PROBLEM TO BE SOLVED: To use an inexpensive crystal oscillator with relaxed precision by extending a pull-in enable range of automatic frequency control(AFC) to make a reception frequency stable. SOLUTION: An AFC correlation device 9 of a different system from a data demodulation correlation device 6 is provided, and the receiver is provided with a control means 14 that sets an integration time of the AFC correlation device 9 independently of an integration time of the data demodulation correlation device 6 to decrease an integration time of the AFC correlation device 9, so as to extend the phase rotation speed detection range due to an error in the carrier frequency in a carrier phase rotation detection circuit 10. Thus, when power is applied, the AFC pull-in range is extended and after the end of pull-in, the S/N is enhanced and the AFC control residual difference can be suppressed small.

Title: Drilling device for printed board
Inventor: SHIRAISHI HIROYUKI
IPC: H05K3/00
Filed: 1989-10-26
Abstract: PURPOSE:To prevent a crack between adjacent holes by providing a short and long difference in the lengths of adjacent punching punches of the punching punch forming a through hole on a printed board. CONSTITUTION:The side pressures generated from long punching punches 14x and 14z give no large effect on the scheduled hole 17b which is penetrated by a short punching punch 14y. The side pressure generated from the short punch 14y gives no large effect on the holes 17a and 17c because of the holes 17a and 17c being already penetrated by the long punches 14x and 14z even in case of the short punch 14y penetrating a printed board 1. The side pressure flared onto the circumference of mutual holes is not generated simultaneously by giving long and short difference in the lengths of mutually adjacent punches and a crack can thus be prevented.

Title: Method for detecting collision in lan, collision detector and its terminal
Inventor: IWAI MASASHI
IPC: H04L12/46
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To surely detect collision of data in a LAN branched in terms of high frequencies. SOLUTION: The LAN that is branched in terms of high frequencies is provided with a collision transmission 10 and terminals 30. Each terminal 30 has a detection signal generation section 35 that generates a collision discrimination AC signal, thereby a collision discrimination AC signal Fs is generated in the case of data transmission. Since the Fs is an AC signal, the signal passes through each branching device 20 and propagates up to the collision detector 10. The collision detector 10 superimposes the signals and discriminates collision of data based on an amplitude of the superimposed signal. Since frequencies of the collision discrimination AC signals Fs sent from the terminals 30 differ slightly from each other, a maximum amplitude is surely obtained. When this amplitude is a prescribed amplitude or over, occurrence of collision is discriminated.  Thus, access control of the CSMA/CD system is available by using this collision detection method even in the case of the LAN that is branched in terms of high frequencies.
