Patent JP-H0582561-A (JP)
Title: Semiconductor device
Inventor: TSUJI HIROMI
IPC: H01L21/338
Filed: 1991-09-24
Abstract: PURPOSE:To provide a semiconductor device provided with a FET and a an electrode (for instance, an electrode of a Schottky diode in a level shift circuit) which is provided adjacent to the FET and to which a negative voltage larger than that applied to a source electrode is applied, where a side gate effect is hardly induced as compared with a conventional one. CONSTITUTION:In a FET 53, a drain electrode 53d is arranged on the same side as an electrode 55. By this setup, when the FET 53 becomes high in drain voltage, holes are generated in the channel region of the FET to flow into the other electrode 55, but the generated holes are prevented from flowing into the electrode 55 by a positive potential barrier induced at a substrate under the drain electrode 53d.

Title: Fsk signal demodulator
Inventor: KAMEI HISAAKI
IPC: H04L27/148
Filed: 1990-09-14
Abstract: PURPOSE:To improve the S/N of a demodulation signal by employing a low pass filter LPF and a high pass filter HPF and dividing a frequency component included in an FSK signal into two at a center frequency location to convert upper and lower undesired frequency components into signal components. CONSTITUTION:A frequency component whose frequency is lower than a center frequency included in an inputted FSK(Frequency Shift Keying) signal passes through an LPF 13 and converted into a voltage signal smoothed by a 1st detection element 15 and a capacitor 18 and a frequency component higher than the center frequency included in the FSK signal passes through an HPF 14 and converted into a voltage signal smoothed by a 2nd detection element 17 and a capacitor 19. Even when lots of frequency components in the neighboring of designated frequencies f1, f2 in addition to them are included in the FSK signal, the frequency components are shared to the lower and upper frequency components around the center frequency and the shared components pass through each filter. Thus, since the frequency components being noise components are extracted as signal components, the S/N of the voltage signals smoothed and outputted from the detection elements 15, 17 and the capacitors 18, 19 is considerably improved. Thus, the S/N of the final demodulation signal is improved.

Title: Solid-state image pickup element and manufacture thereof
Inventor: MORI HIROYUKI
IPC: H01L27/14
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To prevent smear from occurring by forming an anti-reflection film as a low-reflection film, which forms an upper layer than a light-shielding film while at least covering the entire imaging region. SOLUTION: Related to a solid-state image pickup element, a low-reflection film 5 is formed as a layer that forms the upper layer of a light-shielding film 6, while entirely formed at least in an imaging region. Since the low-reflection film 5 is entirely formed and no gap occurs to an end surface facing the light- receiving window of the light-shielding film 6, no diagonal light comes from the outside of the light-receiving element through the gap between the light- shielding film 6 and the low-reflection film 5, resulting in very little smear. With the method for manufacturing it, the low-reflection film 5 is entirely formed after the light-shielding film 6 is selectively formed, so a solid-state image pickup element is easily provided. Here, it is required to be entirely formed at least in an imaging region, so no minute patterning is required. Thus, formation of a low-reflection film is very easy.

Title: Hydraulic pressure type booster device
Inventor: TOTSUKA TAKASHI
IPC: B60T13/12
Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To solve the problem of rattling sounds arising from the part of a throttle valve without reducing servo pressure generated in a servo chamber. SOLUTION: A method whereby pressures in front of and behind a throttle valve are reduced in two steps is employed. The throttle valve used includes a first valve 710 located closer to an inlet and a second valve 720 located closer to an outlet, on the axis of a pool 600, the area contracted by the second valve 720 being greater than the area contracted by the first valve 710. For example, of pressure differences equal to or exceeding 120 kg/cm<2> needed in front of and behind the throttle valve, the range wherein the problem of rattling sounds does not arise, e.g. the range of 100 to 120 kg/cm<2> , is allotted to the first valve 710, while the remaining range of 20 to 30 kg/cm<2> is allotted to the second valve 720.  Therefore, no pressure differences such that the problem of rattling sounds arises are gnerated between in front of and behind the actual throttle (main throttle by the first valve 710 and auxiliary throttle by the second valve 720).
