Title: Control method for hydraulic system
Inventor: MASAMURA TATSUYA
IPC: B60G17/015
Filed: 1990-06-20
Abstract: PURPOSE:To immediately control rolling and pitching during running regardless of the position of each acceleration sensor by correcting the lateral acceleration and the longitudinal acceleration by signals obtained by multiplying the roll angle acceleration and the pitch angle acceleration by proportional constants. CONSTITUTION:A roll angle acceleration signal alpha and a pitch angle acceleration signal beta are obtained by computing signals Za, Zb, Zc from vertical acceleration sensors (a), (b), (c) by an acceleration arithmetic portion 19 and computing the same with a vertical acceleration signal Z by a bounce control arithmetic portion 20 and taken as bound control output to each control valve 5 of four wheels. A lateral acceleration signal S and a longitudinal acceleration signal F, which have already been subtracted by signals alpha beta multiplied by proportional constants HP and HR and corrected, are respectively subdivided into the front sides 22, 23 and rear sides 21, 24 of a vehicle to be processed, and then added or subtracted by a ground clearance holding signal H to be output as control command (i) to each control valve of four wheels. The proportional constants HP and HR are respectively calculated according to the distance Hr between the roll center R and the sensor S and the distance Hp between the pitch center P and the sensor (f).

Title: Pll frequency synthesizer circuit
Inventor: MAEDA YASUE
IPC: H03L7/187
Filed: 1988-06-28
Abstract: PURPOSE:To obtain an FM frequency with broad band and simple and inexpensive circuit by providing a resistance split circuit, its driver, a shift register and a reference signal generator and employing a programmable frequency divider as the frequency divider. CONSTITUTION:With a modulation signal Sin fed to an adder 23, the adder 23 supplies a signal S23 being the addition of the signal Sin to an output signal S22 of a loop filter 22 to a VCO 24. Thus, similar out-band FM similar to a conventional circuit is attained. On the other hand, a signal S30 being the result of amplification of the signal Sin is adjusted to a level corresponding to a channel by a resistance split circuit 31 in which a prescribed resistance is set and the resulting signal S30 is given to a reference signal generator 32. The generator 32 outputs a reference signal Fa having a frequency corresponding to the signal S31 is outputted to a phase comparator 21. Thus, an output signal S24 of the VCO24 is frequency divided by the division frequency set by a frequency division data N at a programmable frequency divider 25 and a frequency division signal S25 is fed back to the comparator 21. The comparator 21 compares the phase of the signal Fa with the phase of the S25 and gives the signal S21 to the filter 22, then the in-band FM carrier is obtained.

IPC: G02B5/22
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To make color reproduction uniform and to enable the correction of aberrations at a low cost. SOLUTION: The IR cut filter 33 is arranged between an image pickup element 32 and an image pickup lens 31. The IR cut filter 33 is formed of a plastic material having nature to absorb IR rays and the thickness (a) thereof is nearly uniform. The filter has curved surfaces 39, 40 curved to direct their concave surfaces toward the image pickup lens 32 side. These curved surfaces 39, 40 are rotationally symmetrical surfaces around an optical axis 37. For example, the curved surfaces 39, 40 are formed to a spherical shape having the center of curvature near the top of an exit pupil 35. The refracting power of the main ray 36 in the IR cut filter 33 is smaller than the refracting power of the main ray 36 in the image pickup lens 31.  The difference in the transmittance of the IR rays may be relieved and the color reproduction of an image pickup plane can be made uniform by this IR cut filter 33.

Abstract: PURPOSE:To improve electrical properties and reliability by a method wherein an opening is formed of which section is bowl-shaped and a gate electrode forming metal deposited on a surface which contains the opening is selectively etched for the formation of a Y-shaped gate electrode. CONSTITUTION:The rest of an opening of an aluminum film 3 is removed by anisotropic etching using a CCl4+He gas through a silicon oxide film 4 used as a mask so as to expose the surface of a GaAs active layer 2 and form an opening 6 of which section is bowl-shaped.

After that, the silicon oxide film 8 deposited on the part other than a vertical side wall of the opening 6 is removed, and WSi, Ti, Pt, and Au are deposited on the surface which includes the opening successively through a sputtering method and then selectively etched in succession for the formation of a gate electrode 9. Further, the aluminum layer 3 and the silicon oxide film 8 are removed successively for the formation of the Y-shaped gate electrode 9. By these processes, the gate electrode is reduced in a parasitic resistance and improved in high frequency properties.

Abstract: PURPOSE:To reduce remarkably an overhead of software, by connecting communication equipments belonging to computer systems which are different from each other by a transmission line, and executing directly a data transfer to the communication equipment between the input/output controllers connected to each data bus. CONSTITUTION:A channel controller 2A fetches an input instruction from a processing device 1A, sends it to a communication equipment 6A, and the equipment 6A sends its instruction to a communication equipment 6B.

Abstract: PURPOSE:To reduce the flickering on a large screen TV, by installing a memory which stores the signal of one horizontal scanning and a delay circuit of one-field scanning time, and scanning the outputs from the delay circuit at a double speed. CONSTITUTION:When signals having one-field information and represented by A, B,..., respectively, are successively inputted into an AD converter 15, the signals are converted into digital signals and the signals A, C, and E are supplied to a delay circuit 17 and memory 19 and the other signals B, D, and F are supplied to another pair of delay circuit 18 and memory 20 by means of a switch 16. Since the delay circuits 17 and 18 have a delay time of one-field scanning time only, the same content is read out for two times within one horizontal scanning time, and TV signals converted into analog signals at DA converters 21 and 22 are alternately outputted via a switch 23 which performs the change- over operation at 1/2 horizontal scanning time.
