Title: Internal combustion engine with mechanical supercharger
Inventor: KATO YUICHI
IPC: F02D9/02
Filed: 1991-11-14
Abstract: PURPOSE:To prevent the deterioration of acceleration responsiveness caused by a throttle valve when intake air is compressed and heated by operating a mechanical supercharger in cold running of an engine and throttling an air intake passage by means of an throttle valve provided in the air intake passage down-stream of the supercharger. CONSTITUTION:The opening degree of the throttle valve 12 provided in an air intake passage 2 downstream of a supercharger 5 is controlled according to the opening degree of a throttle valve 3 and is held so that the area of the flowing passage of the throttle valve 12 becomes larger than that of the flowing passage of the throttle valve 3. With this constitution, the throttle valve 12 is prevented from hindering the increase in the flow rate of intake air caused by the increase in the opening degree of the throttle valve 3 when an engine is accelerated, without causing the deterioration of acceleration responsiveness.

Title: Optical transmitter
Inventor: ONAKA HIROSHI
IPC: H04B10/40
Filed: 1989-11-20
Abstract: PURPOSE:To keep the modulation efficiency constant independently of the aging of a coherent light source by controlling the amplitude of a modulation signal so that the modulation efficiency of a high frequency component of the signal from a light receiving means is constant. CONSTITUTION:Frequency stabilizing means 5 is provided, which detects the frequency fluctuation of an output light of a coherent light source 1 based on a signal from a light receiving means 3 to control the driving condition of the light source 1 so as to cancel the fluctuation. A prescribed frequency discrimination curve is obtained from the relation between the output of a divider 38 of the means 5 and the frequency of light from the light source 1 by setting an interference optical length of a light interferrometer 18 properly. Thus, the bias current of a semiconductor laser 12 is set so that the light frequency from the light source 1 is within the frequency range giving an increase or decrease in the discrimination curve. Then a relevant reference voltage is set to stabilize the frequency. On the other hand, a modulation efficiency stabilizing means 4 controls the amplitude of the signal from the light receiving means 3 to be constant so that the deterioration in the modulation efficiency due to aging is prevented.

Title: Instrument for measuring horizontal wheel pressing force
Inventor: WATANABE SHINICHI
IPC: G01L5/00
Filed: 1988-11-30
Abstract: PURPOSE:To accurately measure a horizontal wheel pressing force by eliminating the influence of the horizontal burden force of a running wheel when the horizontal wheel pressing force is measured. CONSTITUTION:At the time of measurement, a fixed cylinder 6 is pulled in by operating a fixed cylinder operating device 17. As a result, a running wheel ground-contacting plate 5 becomes free in the horizontal direction by means of a rolling device 7 and the road surface contacting force of a running wheel 2 becomes the vertical component only. In such state, double-acting cylinders 11 and 15 are pulled in and a guide wheel load sensor 9, stabilizing wheel load sensor 13, guide wheel ground-contacting plate 8, and stabilizing wheel ground- contacting plate 12 are retreated. As a result, gaps are produced between horizontal wheels 3 and 4 and the ground-contacting plates 8 and 12. When the gaps are produced, the double-acting cylinders 11 and 15 are extended until normal stringer widths are obtained by operating a hydraulic device 16 after zero balance is set in a digital horizontal wheel pressing force indicator 18 and the horizontal wheel pressing force is measured. Therefore, the influence of the running wheel 2 can be prevented when the pressing forces of the horizontal wheels 3 and 4 are measured, since the horizontal force burdened by the running wheel 2 can be relieved by means of a rolling device 7 supporting the running wheel ground-contacting plate 5.

Title: Water wheel type speed detector of small ship
Inventor: YANAGIHARA HISASHI
IPC: B63H11/00
Filed: 1994-12-05
Abstract: PURPOSE: To prevent the rotational speed from varying caused by the external water or the like and improve detecting accuracy by covering the front and at least the upper front of a paddle in the flowing direction of fluid with a cover member. CONSTITUTION: A speed detector 30 is constituted such that a cover member 33 is separately attached to a sensor body 30a having a paddle rotatably disposed on a support member 31. The cover member 33 made of polypropylene is constructed by a front wall 33a covering the front of the paddle 32, a top wall 33b covering above the paddle, side walls 33c, 33d covering the left and right sides of the support member 31 and a bottom wall 33d following the sidewall 33c and turned to the lower surface of a flange part 31a of the support member 31 which are all formed integrally. Since the front and upper of the paddle 32 are cover with the cover member 33, a splash of engine cooling water or the like drained to a jet pump chamber 29 is not splashed directly on the paddle 32.  Thus, the rotational speed of the paddle 32 can be prevented from varying caused by the splash of the drain water or the like to improve the accuracy in detection.

Abstract: PROBLEM TO BE SOLVED: To provide an optical image recording device for focus image detection which is free of defocusing by providing an adjusting means which slants (changes a position) a 1st focus plane in the directions of two axes in the optical path of a lighting raster generator. SOLUTION: The focus plane 13 of a microlens array 11 is made incident on the observation optical path 16 of a microscope so that an image of the focus 13 of the array is formed on a body 7 to be observed through optical systems 14 and 15. The lens array 11 constitutes the lighting raster generator which generates light spot raster. The lens array 11 can easily by slanted by three piezoelectric position adjusters 12a, 12b, and (12c), and the focus plane 13 also slant correspondingly, so that the image of the focus plane 13 is formed sharply on the body 7 with only a light spot having a strictly matching focus position. Therefore, only a series of sharp image spots is seen in an image of a CCD detector 22. The tilt angle of the microlens array 11 can freely be set and the sensitivity of the optical systems can easily be adapted to various different magnifications.

Abstract: PURPOSE:To accurately display image data from the outside in the state of maintaining high horizontal resolution by reading out line data at every one scanning line from an image storage part at a higher frequency than a write frequency and inserting interpolation line data into between mutual line data at every a fixed period. CONSTITUTION:An inputted image signal (a) is converted into digital image data by a reference clock signal (b) and written in the image storage part 5. The image data stored in the image storage part 5 are read out as the line data at every one scanning line by a display clock signal faster than the reference clock signal (b). Then, the same line data are read out as the interpolation line data whenever the fixed number of line data are read out, and are inserted into between mutual line data and displayed. Then, the number of scanning lines existing in a vertical synchronizing interval is increased in pseudo. Thus, the aspect ratio of respective pixels displayed are set to 1:1 in the state that the high horizontal resolution is maintained.
