Title: Solid state image pickup device and its driving method
Inventor: SEN TETSUO
IPC: H04N5/335
Filed: 1992-11-10
Abstract: PURPOSE:To improve dynamic resolving power by reading a storing electric charge in an electric charge transfer column. CONSTITUTION:The combination of photodiodes which are electric charge-mixed is changed by two rows, the same kind of an electric load is read and transfer is executed. That is, concerning the photodiode under a green filter, G1+G2 is adopted and the electric charge of G2+G3 are mixture-transfered. In a same way, concerning an electric signal read from the photodiode under a blue filter or a red filter, the electric charge of B2+B3 and R2+and R3 are mixed. Thus, the electric signal of an interlacing system is obtained by deviating the electric charge to be mixed for the portion of the two rows. Since the storing electric charge of all the photodiodes are read in respective electric readings, electric charge storing time concerning the respective photodiodes becomes T and it takes half time compared with a still mode so that dynamic resolution force is improved.

Title: High pressure solenoid valve
Inventor: KOBAYASHI AKIYUKI
IPC: F16K31/06
Filed: 1996-11-12
Abstract: PROBLEM TO BE SOLVED: To prevent slip-off of valve rubber caused by a high pressure fluid by boring a through hole with an opening in a valve rubber mounting face at the end face of a plunger in a high pressure solenoid valve used to control the flow of a high pressure fluid. SOLUTION: A plunger 14 is attraction-lifted by exciting a fixed core by applying a current in a valve closed state. At a pilot port 36 of small opening area, valve rubber 40 integral with the plunger 14 is spaced from a pilot valve seat 37. In a valve hole of large opening area, a main valve 31 is pressed to the valve seat by pressure from a primary chamber so as to be left closed, and high pressure gas in the primary chamber flows to a secondary chamber from the pilot port 36 so as to rapidly lower pressure in arecessed part 35 of the main valve 31,  but pressure on the mounting face side is also lowered in association with rapid lowering of pressure around through a breathing hole 43 of the mounting face of the valve rubber 40 so as to improve gas flow around the valve rubber 40 through a clearance 42 between the valve rubber 40 and a valve rubber fitting 41 and thereby to space the main valve 31 from the valve seat. As a result, slip-off of the valve rubber 40 caused by a high pressure fluid can be prevented.

IPC: G01R23/10
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To widen the dynamic range of a frequency measuring instrument regardless of the limited data length of a storage circuit by providing a data converting circuit which converts the data length of a count value having a long data length into the short data length of the storage circuit. SOLUTION: A counter circuit 2a counts the output clock of a reference clock circuit 1 until the second rising pulse of an input signal 100 from the first rising pulse of the signal 100 and the count value of the circuit 2a is temporarily stored in a latch circuit 3a . A control circuit 5 adds three-bit data to the high-order bit of the count value as a range code when the data length of the count value is equal to or shorter than the data length (for example, 16 bits) of a storage circuit 4. When the count value is longer than the data length of the circuit 4, the circuit 5 stores the count value in the circuit 4 after converting the data length of the count value into the data length of the circuit 4. Therefore, the dynamic range of a frequency measuring instrument can be widened even when the data length of the circuit 4 is limited.

Abstract: PURPOSE:To eliminate the need of a circuit which squares the output of the 2nd detecting means so that an MSK signal demodulator can be integrated advantageously by generating a clock signal by multiplying the output of the 1st detecting means by the output of the 2nd detecting means. CONSTITUTION:This demodulator is constituted so that the output signal of a multiplier 13 can be given to a clock reproduction circuit 20 as a reference signal by paying attention to that the signal obtained by multiplying the output signal I of a detector 11 by the output signal Q of another detector 12 contains a clock frequency component (sin(4omegad.t)). Therefore, the square circuit which has been conventionally provided in the poststage of the detector 12 becomes unnecessary. While a timing discriminator 24 becomes slightly complicated, since the discriminator 25 is constituted so that the discriminator 24 can shift the phase of square waves given from an amplitude discriminator 17, it can be constituted of a well known digital circuit.
