Title: Spheroidal graphite cast iron with high rigidity
Inventor: OKADA YUJI
IPC: C22C37/04
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To increase rigidity by improving Young's modulus by the reduction of CE value and also to prevent the occurrence of shrinkage cavity. SOLUTION: The carbon equivalent (CE value), computed by CE=(Si+P)/3+C according to the contents of C, Si, and P expressing in a mass ratio, is regulated to a value ranging from 3.4 to 4.0%, and the contents of C and Si expressed in the mass ratio satisfy C>=Si/3+2.53, and further, the content of Si expressed in the mass ratio is regulated to >=1.0%. The occurrence of shrinkage cavity can be effectively prevented while increasing rigidity by raising Young's modulus to >=180 GPa. The occurrence of shrinkage cavity can be prevented more effectively in the case where Si content is <=1.4% in particular.

Title: Plotting device
Inventor: ONOZAWA YUJI
IPC: G06T11/40
Filed: 1993-07-02
Abstract: PURPOSE:To provide the plotting device capable of the high-speed processing by remarkably reducing a memory to be used when paint-out processing by pattern is performed at the time of converting input data into raster information. CONSTITUTION:An edge list generation part 5 generates an edge list for the input data inputted to a plotting input part 2. Clip processing is performed by a clip processing part 6 and the input data are sent to a coloring processing part 8. The part 8 compares the edge list of the pattern stored in a pattern memory 9 with the edge list of the input data and regenerates the edge list. Thus paint-out processing by pattern is performed. The regenerated edge list is merged to the edge list for one page by an edge list merge part 10 and raster- converted by a rasterise part 12 and outputted to an output device 14.

Title: Transmission torque controlling device for four-wheel-drive vehicle
Inventor: WATANABE KENICHI
IPC: B60K17/348
Filed: 1985-08-30
Abstract: PURPOSE:To prevent unstable oscillation when a car is running at a low speed by fixing the characteristics, which control the transmitted torque amount of a power transmission means based on the measurement of such items as the difference in rotation speed between a front and a rear wheel, a car speed, and a car body speed ratio, at the value for a low speed range. CONSTITUTION:Such signals as Sv, Sa, and SDELTAn from each of sensors are inputted into a control unit 14 so as to allow Sa to form a judgement as to whether a car is running straight ahead or is making a turn. Then such a control curve as 11, 12, and 13 of M1, or 14, 15, and 16 of M2 which corresponds each of running conditions, is selected based on a car speed or a steering angle by means of a control map M1 or M2, or operation formulas. Then the selected curve is checked up with the signal SDELTAn for the difference in rotation speed so as to determine controlling electric current 'i'. And a hydraulic pressure proportional to the current is applied to a clutch 5 by a hydraulic control valve 13 so that the clutch is joined so as to transmit the torque Tr proportional to the joining force to a propeller shaft 6. And the torque is controlled in such a way that the control characteristics is fixed at a value l0 for V=Vmin in case of V<=Vmin. With this, unstable oscillation can be prevented when the car is running at a low speed.

IPC: H03H7/25
Filed: 1992-07-20
Abstract: PURPOSE:To continuously vary the amplitude of a clock signal outputted to the insulating terminal of a four-terminal type directional coupler by connecting a pin diode to each of two output terminals of the directional coupler, respectively, and varying a current to be supplied to the pin diode. CONSTITUTION:The pin diodes 2, 3 are connected to the output terminals 12, 13 of the directional coupler 1, respectively, and furthermore, variable currents are supplied from DC power sources 6, 7 to the pin diodes 2, 3 via resistors 4, 5, respectively. At this time, since the clock signal outputted to the output terminals 12, 13 is terminated with impedance equivalent to that of the diodes 2, 3 different from the characteristic impedance Z0 of the directional coupler 1, mismatching occurs, and a reflection signal is generated. The reflection signals inputted from the output terminals 12, 13 are distributed to terminals 11, 14. As a result, it is possible to vary a reflection coefficient by controlling the currents on the pin diodes 2, 3 by the DC power sources 6, 7, and to vary the amplitude of the output signal of the insulating terminal 14.

Filed: 1992-06-25
Abstract: PURPOSE:To provide an in-phase synthesis type SD receiver in which opposite phase synthesis is avoided in the process of synthesis/restoration of a sub-signal when a fault in an SD control system is recovered. CONSTITUTION:This receiver is provided with a quadrature amplitude modulation type endless phase shifter(EPS) 2.

Title: Projection type rangefinding device for camera
Inventor: ISHIGURO MINORU
IPC: G02B7/32
Filed: 1987-07-31
Abstract: PURPOSE:To rapidly attain the measurement of distance by irradiating an object with flash light once by a light projection part, deciding the obtained level of a photoelectric output and starting integration for a certain time by an integrator after switching the gain of an amplifier or the intensity of light from the projection part. CONSTITUTION:An LED 11 is flashed once just before starting the integration for an actual range finding action. And when the photoelectric output at that time is above a specified level, the gain of the differential amplifier 38 is switched to a low one and thereafter the integration for a certain time is started. Then, it is evaded that the output of signal from the differential amplifier 38 is saturated or the capacitor 53 of the integration circuit 48 is overcharged, so that a rangefinding signal without an error can be obtained. Now, it is good to adjust the level of the output of the signal before integration by altering the luminance of the light projected to the object. Thus, the precise and rapid range-finding action can be executed.

Abstract: PURPOSE:To enable a continuous sheet to be mounted easily on a tractor wheel feeder by detecting a state of 'no sheet loaded' when a continuous sheet is used in the bottom feed mode and opening a bale shaft. CONSTITUTION:It is interpreted whether a continuous sheet 2 held by a base shaft 1 is loaded and is fed by a tractor wheel feeder 3, or a state 'no sheet is loaded' is present, and if it is not the state, it is detected whether a bottom feed selection switch provided on a tip switch 4 is turned ON, which enables the continuous sheet to be introduced from underneath as a bottom feed. If the bottom feed selection switch on the tip switch 4 is turned ON, it is interpreted whether the bale shaft 1 is open. If the bale shaft 1 is not open, the bale shaft 1 is opened under control. The continuous sheet 2 can be easily mounted on the tractor wheel feeder 3 by passing the sheet 2 to the top from an inlet at the bottom of a printer in a state where the bale shaft 1 is open.
