Title: Optical scanner
Inventor: SUGINO TAKASHI
IPC: G03G15/04
Filed: 1981-07-02
Abstract: PURPOSE:To prevent the irregular pitches of the scanning line on a moving body by detecting the scanning pitches and controlling the driving of a rotary mirror or the moving body. CONSTITUTION:The reflected light obtained when the scanning line LB1 scanned by a rotary polyhedral mirror 7 passes on a grating 2 is converted to an electric signal P1 by a photodetector 9. This signal P1 is converted to the driving voltage D1 inversely proportional to the scanning pitch 3 of the line Lb1 with a controller 13, and a driving motor 12 is controlled. It is so controlled that when the scanning pitch decreases the rotating speed of a photosensitive drum 1 is increased so as to increase the scanning pitch and when the scanning pitch increases the rotating speed is decreased to decrease the scanning pitch, whereby the scanning pitch is made constant. In this way, the irregular pitches of the scanning line is prevented.

Abstract: PURPOSE:To generate maximum torque at a low fuel cost in an instantaneous travelling state before a vehicle shifts to a long-run travel by providing a means for controlling a fuel injection means so as to reduce an air-fuel ratio when the time of generating maximum torque is equivalent to a long-run traveling time. CONSTITUTION:When it is judged that a driver calls for a high-load operation, from an intake-air pressure or throttle opening, a control means 10 determines a present air-fuel ratio from the manifold air pressure MAP, the manifold air temperature MAT, and the number of revolution N, and controls a fuel injecting means 11 so that the present air-fuel ratio becomes an air-fuel ratio corresponding to maximum torque which is dependent on the manifold air pressure MAP and the number of revolution N. After that, when the time of generating the maximum torque is continuous to be equivalent to the long-run traveling time, the control means controls the fuel injecting means 11 so that a rich air-fuel ratio corresponding to a smaller torque than the maximum torque can be obtained, in order for components in the exhaust system not to be damaged.

Abstract: PROBLEM TO BE SOLVED: To provide a signal receiver capable of efficiently and exactly detect a signal even when a received signal is vague. SOLUTION: A preamble symbol detector 306 in a signal receiver 300 calculates a correlation value between a reference preamble symbol as a known symbol and a reception symbol composed of a preamble symbol P and an information symbol I and detects whether that correlation value is at a prescribed level or not. When the correlation value is at the prescribed level, a trigger signal TRG is outputted and the operation of a fast Fourier transforming circuit 304 and a demodulator 305 is started. Namely, when the correlation value is lower than the prescribed level, the fast Fourier transforming circuit 304 and the demodulator 305 are not operated.

Title: Ionization chamber for sensing equivalent dosage at 1cm depth
Inventor: MASUI KAORU
IPC: G01T1/185
Filed: 1990-04-20
Abstract: PURPOSE:To sense easily the equivalent dosage at one-cm depth (H1cm) by setting the ratio of the vessel capacity of an electric dissociation box to the area of the surface of an electricity collecting electrode occupied by No.1 electroconductive region, the Ni content of a Ni-containing synthetic resin, and the material of a filter and its thickness. CONSTITUTION:Radiations 12 having penetrated the vessel 9 of an ionization chamber dissociate the air 11 in the vessel 9, which is further promoted by electrons beaten out of nickel in No.1 electroconductive region 17 of an electricity collecting electrode 4 when the radiations 12 having penetrated the vessel 9 are cast to the nickel. Therefore, the value of a radiation sensing signal 15a is enlarged, and radiations 12 with low energy willing to be incident into the vessel 9 are absorbed by a filter 16, so that the value of the signal 15a is lessened in the low energy region of radiations 12 incident into the vessel 9. Thus the energy characteristics of the ionization chamber become an approximation of the H1cm characteristics. Thereby the Hcm value of radiation can be sensed easily.
