Patent JP-2001028454-A (JP)
Title: Semiconductor photodetector
Inventor: KUHARA MIKI
IPC: H01L31/0232
Filed: 1999-07-15
Abstract: PROBLEM TO BE SOLVED: To prevent the stray light of transmission light from entering by providing an absorption layer for selectively absorbing the transmission light on a substrate and at the same time directly below a light receiving layer in a device for transmitting and receiving reception light with long wavelength and the transmission light with short one. SOLUTION: Incidence light A of λ2 entering from backside is absorbed by a depletion layer 62 for forming an electron/hole pair. This is a region for picking up light. By backward biasing, the electron and hole run to n- and p-type regions, respectively, for allowing photocurrent to flow. This is photoelectric conversion operation of normal PD. However, incidence light B of λ1 (transmission light wavelength) similarly entering from the backside is absorbed by an n+-InGaAsP absorption layer 58. Since the light B of λ1 does not reach a light receiving layer 59, the PD does not have sensitivity to the transmission light wavelength λ1. Even when incidence light C of the λ1 enters the PD from a slanting lower part, the incidence light C is absorbed by the absorption layer 58 and does not reach the light receiving layer 59, thus preventing sensitivity to light B and C of λ1.

Abstract: PROBLEM TO BE SOLVED: To improve the reliability by forming various insulation films between overlapped parts of source and drain diffused regions formed in gate electrodes and semiconductor substrate. SOLUTION: A thermally oxidized film 105 is formed on gate electrodes 104 of MOS transistors and source and drain diffusion regions 102. An insulating film 106 is buried in overlapped parts of the gate electrodes 104 and source and drain diffusion regions 102. By CVD method a nitride insulation film 106 is deposited.

Title: Vehicle key and communication controller of same
Inventor: NISHIYAMA KATSUHIKO
IPC: B60R25/04
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To facilitate discrimination of an authorized vehicle key even if there are a plurality of keys used collectively. SOLUTION: This key starts to be charged when receiving a carrier wave for charging from an immobilizer controlling device, and when charging is complete, code hopping is generated with a code hopping generating portion 56. Then, a timing controller portion 54 activates a switch portion 52 according to the delay timing corresponding to that code hopping so that an identification code is sent out from a transponder. The delay timing differs every time since the code hopping code generated every time differs. This makes it so that a plurality of identification codes are not sent from a plurality of keys simultaneously. Therefore, even if a plurality of keys are used collectively, identification codes are sent out from respective keys at different timings such that the immobilizer controlling device can easily discriminate the identification codes.

Filed: 1982-11-19
Abstract: PURPOSE:To remove dust and paper powder attached to a feeding belt by drawing an air-suction port near to a conductive fiber brush in touch with at least one of a paper-feeding means and a hooking means. CONSTITUTION:On one face of a box-shaped housing 2, an opening 3 is opened.

Title: Target tracking method
Inventor: KIRA FUMIO
IPC: G01S3/786
Filed: 1995-08-09
Abstract: PROBLEM TO BE SOLVED: To accurately detect the direction of a target moving at a high speed by catching the signal of a target by a receiving antenna having asymmetric directionality to record a change with the elapse of time and comparing this change with the elapse of time with the supposed locus of the target and the calculation value of a change with the elapse of time being the receiving level output of the receiving antenna. SOLUTION: When an antenna having antenna directional characteristics asymmetric in both of a ϕ-direction and a θ-direction is used as a receiving antenna and the passing locus of a target is shown by a figure code 6, the signal receiving level at time t=T8 becomes high as compared with the signal receiving level at a time when the passing locus of the target is shown by a figure code 8 because of the side lobe shown by a figure code 27. Therefore, the passing locus of the target is decided to one. The calculation of the receiving level based on the directional characteristics of the antenna or analysis such as the comparison of this level with an actual receiving level is performed by a data processor.
