Title: Micro wave doppler sensor
Inventor: TORITSUKA HIDEKI
IPC: G01S13/536
Filed: 1990-09-20
Abstract: PURPOSE:To achieve a high reception sensitivity and enable radiation power to be restricted by introducing a reflection wave which is emitted and obtained from an antenna by utilizing a leak wave from a drain terminal side of an FET to a gate terminal side as a Doppler output signal from a drain terminal of the FET. CONSTITUTION:A micro wave signal source 1 is connected to a drain terminal 6D of an FET 6 and a small amount of micro wave which leaks from the terminal 6D to a gate terminal 6G is radiated through an antenna 4. Then, the transmitted micro wave is shifted at a traveling target by Doppler frequency and becomes a reflection wave and then is supplied to the terminal 6G through the antenna 4. Then, it is amplified by the FET 6 and is outputted to the termi nal 6D. At this time, by mixing with a micro wave from a signal source 1 according to non-linear characteristics of drain voltage versus drain current of the FET 6, frequency constituents of difference of transmission and reception frequency, namely only a low-frequency Doppler output signal, is outputted to an output terminal 5 through a low-pass filter 7 from the terminal 6D.

Title: Typographic printer
Inventor: TAKEKOSHI TARO
IPC: B41J7/48
Filed: 1990-09-20
Abstract: PURPOSE:To prevent noise emanated from a backward rotation-checking mechanism from diffusing directly to the outside of a type drum by placing the position of the backward rotation-checking mechanism on the inside of the type drum. CONSTITUTION:Contact surfaces 3-h of ratchet teeth 3-f formed on an internal wall of a type drum 3 are constructed so that a very small gap becomes existent between the said contact surface and a front end of a first claw 34-a of a backward rotation- checking claw 34 when selection is made for printing. In a very short period of time when a drum gear 2 and the type drum 3 are made overshot, the backward rotation- checking claw 34 is made to thrust in the direction B, being energized by a spring 35, and is made to enter an area where the claw engages with the contact surface 3-h of the ratchet tooth 3-f. In a very moment right after that, the drum gear 2 and the type drum 3 are about to bounce, but the bounce is checked as the contact surface 3-h of the ratchet tooth 3-f of the type drum 3 runs against a first claw 34-a of the backward rotation-checking claw 34. A backward rotation-checking mechanism consisting of the backward rotation-checking claw 34 and the ratchet tooth 3-f is housed in the type drum 3, and thereby noise source is confined in the type drum 3, preventing diffusion of the noise to the outside.

Abstract: PURPOSE:To effectively act a change in the refractive index near a center and to lower the threshold voltage of a switching element by providing a 1st electrode on a 1st waveguide on input and output port sides and continuously between the 1st and 2nd waveguides near the center. CONSTITUTION:The 2nd electrode 42 is formed broad and is superposed on the 2nd waveguide 14 over the entire length of this 2nd electrode. The 1st electrode 40 is superposed on the waveguide 12 on the input port side and output port side of the 1st waveguide 1, is provided to shift toward the waveguide 14 side in the region 20 near the center and is so provided as to exist between the waveguides 12 and 14 in the extreme central part region. Further, the 3rd electrode 44 is provided. The 1st electrode and the field distribution of the light of an even mode overlap when the element is operated by impressing a +DELTAn voltage to increase the refractive index to the 1st electrode and a -DELTAn voltage to decrease the refractive index to the 2nd and 3rd electrodes. On the other hand, the field distribution of the odd mode is poor in the overlap state with the 1st and 2nd electrodes. Then, the difference in propagation constant between the even and odd modes is effectively generated even in the region near the center and the interference effect is utilizable. The threshold value of the operating voltage is thus decreased.

Abstract: PURPOSE:To obtain an X-ray transmitting film whose transmission factor is stable by a method wherein an alignment-light anti-reflection film is formed on the whole surface or in an alignment region on an X-ray transmitting support film and an X-ray absorber pattern is formed on it. CONSTITUTION:An SiNx film 2 which is used as an X-ray transmitting thin film and as a protective film is formed on the whole surface of a silicon wafer 1 by using a low-pressure CVD apparatus. Then, SiO2 3 as an antireflection film is formed by using an EB heating vapor-deposition apparatus. Then, a Ta film 4 as an X-ray absorber is formed by using a sputtering apparatus. Then, a resist pattern is formed on the Ta film 4 by an electron beam exposure operation; in addition, the Ta film 4 is patterned by a dry etching operation; after that, the resist 5 is removed. Then, in order to form a window from the rear, a prescribed part in the SiNx film 2 on the rear is removed by an RIE operation; the revealed face of the silicon wafer 1 is etched by using a hot alkali; and silicon in a prescribed part is removed. Thereby, the influence of reflection by the film-thickness interference of alignment light at a specific wavelength which is incident from the rear of a mask is reduced by the action of the anti-reflection film 3, and it is possible to obtain a high transmission factor which is always stable.

Abstract: PURPOSE: To realize the file transfer device in which the transfer of a file relatively high in security is taken into consideration. CONSTITUTION: Security levels are written in files received by a file read part 22 in relation to transfer destinations. A security management part 26 registers respective transfer destinations and security levels of received files in a security management table 31; and at the time of transfer of a file, the security level of this file is compared with that of the transfer destination, and the file is transferred from a transfer part 41 only when the security level of the transfer destination is higher or security levels of both of them are equal to each other. Consequently, the file is not transferred to secure the safety if the destination designated as the transfer destination of the file has a lower security level.
