Title: Noise reducing circuit in noncontact type electrometer
Inventor: AOKI MINORU
IPC: G01R29/12
Filed: 1979-04-16
Abstract: PURPOSE: To prevent disturbance noise from occurring, by applying to an electric field modulator an output from a current-voltage converter, which is generated in accordance with an electric potential of an object to be measured, and an output voltage from a differential amplifier into which a predetermined D/C voltage is inputted.  
     CONSTITUTION: An electric field generated on the surface of an object 1 to be measured is applied to a detecting electrode 4 as a passing area for the electric field is periodically changed by an electric field modulator 5. An output from the detecting electrode 4 is applied to one of input terminals of a differential amplifier 8 through an operational amplifier 7, and a predetermined DC voltage to the other terminal of the differential amplifier 8. An output voltage from the differential amplifier 8 is applied to the electric field modulator 5 through a shield plate 2 so as to offset an undue potential difference occurring between the electric field modulator 5 and the detecting electrode 4.

Title: Semiconductor device
Inventor: HOTSUTA MASAHIKO
IPC: H01L21/331
Filed: 1979-04-14
Abstract: PURPOSE:To improve the off characteristic of a bipolar-type SIT by having a pattern on the interior circumference edge of a floating gate layer with a polygon type of more than a pentagon or a round shape, and by having the interior circumference pattern of a control gate layer corresponding to the above. CONSTITUTION:In case a channel width or a gate clearance is not uniform, a depletion layer is pinched off at the section where the channel width is narrow, but it is not sufficiently pinched off at the section with a wider width. Besides the distance from the gate to the section is long and the barrier formed by a diffusion  potential is low. Therefore, a sharp cut-off characteristic can not be obtained. Accordingly, in the case of a bipolar type SIT as a flat pattern of the floating gate  layer 20 is made round corresponding to the interior circumference edge of a control  gate layer 18, the width of a channel 16A or a gate clearance becomes a uniform  value a and the off characteristic can be improved.

Title: Production of ceramic part
Inventor: KOJIMA KOICHI
IPC: C04B35/00
Filed: 1989-02-27
Abstract: PURPOSE:To reduce the amount of resin added and to prevent cracking during de-fatting of molded article in a production of ceramic part by injecting molding using an organometallic substance as a sintering auxiliary by simultaneously blending ceramic powder with the organometallic substance and a resin. CONSTITUTION:For example, ceramic powder of Si3N4, a sintering auxiliary of yttrium isopropoxide and spinel powder are weighed in a given ratio. These substances are mixed with an adhesive of isostatic PP, an ethylene-vinyl acetate copolymer and dibutyl phthalate and a lubricant of wax and stearic acid in a specific ratio. The whole blend of these substances is sufficiently kneaded by a closed type pressure kneader (simultaneous kneading process). The prepared kneaded material is injection molded, the prepared molded article is de-fatted and calcined to give a ceramic part. By this method, since the organometallic substance is kneaded not in a pulverized state, the amount of the resin to acquire injection moldability can be reduced.

Title: Detecting device for fuel injection timing for internal combustion engine
Inventor: SAITOU ATSUSHI
IPC: F02M65/00
Filed: 1983-03-18
Abstract: PURPOSE:To control a timing of injection accurately by providing a means to detect a solenoid current of an electrohydraulic valve and a current variation detecting means to detect the discontinuous variation of a rise waveform of the solenoid current which occurs at the time of the suction of the valve. CONSTITUTION:CPU7 delivers an injection signal to a power transistor Tr2 through a driver 5. Thereby Tr2 is turned ON, and thus a current starts to flow from a power source to a series circuit of a solenoid 1, Tr2 and a resistor 3, while counting by a counter 9 is started simultaneously. A voltage at a point B is read repeatedly in CPU7 through an A/D converter 4 and an I/O port 10 for a prescribed period after the current starts to flow. Then the values of the current obtained at the preceding and present times are compared with each other to detect a time at which the value has turned from a decrease into an increase, and the value of a time (t) thus detected is stored in RAM8. When the solenoid 1 is electrified subsequently, said detected value is used for correcting the timing of delivery of the injection signal by the amount of variation of the time (t), and thus the time of injection is controlled accurately.
