Title: Device for detecting pressure
Inventor: KATO MASAAKI
IPC: F02M65/00
Filed: 1988-06-24
Abstract: PURPOSE:To prevent leakage as well as failure caused by high pressure by forming a relief flow passage for connecting a high pressure side with a low pressure side when the high pressure side goes above a defined pressure. CONSTITUTION:When the pressure in an accumulator 2 becomes unusually high for some reason or other, a piston 18 is moved in the direction of compressing a back pressure chamber 38. In this case, when the pressure in the accumulator 2 is a defined pressure, the pressure receiving portion 20a of the small diameter portion 20 of the piston 18 reaches a boundary position L1. When the pressure in the accumulator 2 exceeds the defined pressure, the piston 18 is further moved causing the accumulator 2 to be connected to a discharge port 17 via a small diameter port 10, a taper port 14, and a large diameter port 16. Thereby, the high pressure fuel in the accumulator 2 is returned to a fuel tank 4 via the discharge port 17. As the piston 18 is moved till the pressure receiving portion 22a of the large diameter portion 22 thereof hits against a holder 28, the pressure in the accumulator 2 will not increase any more. Hence, no high pressure will be applied to a pressure sensor 42, also reducing leakage.

IPC: F16H61/02
Filed: 1984-07-28
Abstract: PURPOSE:To improve running performance by controlling switching of a high speed step and a low speed step for an auxiliary speed change gear according to a speed change diagram corresponding to preset acceleration and throttle opening. CONSTITUTION:Outputs from an acceleration sensor 603 and a throttle opening sensor 602 are input to an electronic control unit 600. According to a speed change diagram corresponding to preset acceleration and throttle opening, the switching between a high speed step and a low speed step for an auxiliary speed change gear is controlled.

Title: Liquid detecting sensor
Inventor: KUBOTA YOUICHI
IPC: G01F23/292
Filed: 1983-08-31
Abstract: PURPOSE:To improve S/N, to detect a level, and to improve reliability, by providing both a light emitting part and a light receiving part at the bottom surface of a prism, utilizing the reflection and refraction of light, and detecting liquid. CONSTITUTION:Both a light emitting part 12 and a light receiving part 13 are contacted with a bottom surface 10a of a transparent prism 10 and provided in a head 11. The light from the light emitting part 12 reaches one slant surface 10b of the prism 10. When silicone oil is present at the outside of the slant surface 10b, the light reaching the slant surface 10b is refracted at the slant surface 10b and outputted into the silicone oil. Therefore the light is not detected by the light receiving part 13. When air is present at the outside of the prism 10, the light is reflected by the slant surface 10b and a slant surface 10c as shown by a dotted line. The light is guided to the light receiving part 13 and detected. Therefore, the light receiving part 13 is linked to a signal generating device and liquid is detected. By using a pluraliry of the devices, a level can be checked. The sensor is hard to be affected by disturbance light, and reliability is improved.

Filed: 1981-10-06
Abstract: PURPOSE:To satisfactorily save a half tone information in an expansion and reduction dither picture image, by estimating a density value at every noticed picture element, and binary-coding it again by a dither matrix of expansion and reduction. CONSTITUTION:An original dither picture image S (X, Y) is stored in an original dither picture image memory 1, and after that, a co-ordinate counter 51 in a controlling circuit 5 outputs in order a co-ordinate of a noticed pictre element of an expansion and reduction dither picture element S (x, y). The controlling circuit 5 reads out bit patterns b1-b9 being in the proximity of an object picture element from the original dither picture image memory 1, and information of these 9 bits is outputted to a density value estimating circuit 2. The density value estimating circuit 2 reads out an estimated density value corresponding to this information of 9 bits, and gives it to a dither matrix circuit 3. The dither matrix circuit 3 binary-decides the estimated density value by a corresponding threshold level, outputs it as binary information S (x, y) of the noticed picture element in the expansion and reduction dither picture element, and writes it in a memory 4.

Title: Multichannel optical switch
Inventor: SAWAKI IPPEI
IPC: G02B6/12
Filed: 1984-07-27
Abstract: PURPOSE:To reduce the external size of the multichannel optical switch even when a waveguide type optical switch is provided with plural channels by providing one optical switch at the intersection of two series connected waveguides of two optical switches, and selecting the two series-connected waveguides. CONSTITUTION:Optical switches SW1-SW8 to which one of waveguides 2a and 2b are connected in series are divided into two groups G1 and G2 and optical switches are juxtaposed for both groups G1 and G2. When a light signal is passed through the series waveguide where a preliminary circuit 59 is not connected, the series waveguide where the preliminary circuit is connected is selected with a group changeover switch SWc. Consequently, the series-connected optical switches are divided into two groups G1 and G2 to form juxtaposed constitution, and only one preliminary circuit is enough although the overall length of the element is reduced almost to half, thereby reducing the size of the multichannel optical switch.

IPC: H05K3/46
Filed: 1990-06-15
Abstract: PURPOSE:To greatly reduce improper cutting at an intersection of wires by varying an ultrasonic output necessary to be laid on adhesive and wires when insulated wire is laid on adhesive by a numerical control wiring machine. CONSTITUTION:When a stylus 1 rides over a wire, it is varied vertically. The variation is detected by a noncontact type displacement sensor 2. Its output signal is amplified by an amplifier 3, converted to pulses, a threshold of a desirable value is set at the pulse, and on-wire is detected. Its signal is transmitted to an ultrasonic drive transistors, and an ultrasonic run-output is applied to an idle output. Thus, the ultrasonic output is converted from the run output to an idle output at the crossing point of wires to reduce the amplitude at the end of the stylus from about 35mum of prior art to about 10mum. As a result, an improper cutting can be greatly reduced at the intersection of the wires.
