Title: Acceleration detecting system
Inventor: OKADA KAZUHIRO
IPC: G01P15/18
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To recognize the change in setting attitude of the main body of a sensor. SOLUTION: In an XYZ three-dimensional rectangular coordinate system, a three-dimensional acceleration sensor 10, which outputs respective coordinate components αx, αy and αz of acted acceleration as the electric signals, respectively, is provided. An operating means 20 performs the operation of A=(αx<2> +αy<2> +αz<2> )<1/2> and outputs the operation result A. The operation result by the operating means 20 when only gravitational acceleration acts on the three-dimensional acceleration sensor 10 is stored in a memory means 30 as a reference value A0 beforehand. A judging means 40 outputs a judged signal J, which indicates whether the operation result A by the operation means 20 and the reference value A0 stored in the memory means 30 agree or not.  As long as the judged signal J indicates the agreement, it can be judged that only the gravitational acceleration acts on the sensor main body, and it is recognizing that the abnormality of the detected value is caused by the change in setting attitude.

Title: Automatic speed change gear fitted with lockup
Inventor: KIUCHI MORIO
IPC: F16H61/14
Filed: 1982-10-21
Abstract: PURPOSE:To absorb a torque variation in a transition period of time with a torque converter for a relief as well as to aim at the promotion of smoothness for driving performance, by keeping a lockup device in a state of stoppage for a specified period of time after an accelerator is opened, when a shift lever changes from acceleration to deceleration at the low speed running range. CONSTITUTION:Receiving each output of an accelerator opening sensor and a select range sensor, a shift lever keeps the operation of a lockup device as it is in a forward range other than a D range and an accelerator is in a fully closed state. When the shift lever is left intact in the forward range and the accelerator is opened from a state of being fully closed, a control unit is made up so as to cause the operation of the lockup device to be forcibly stopped for a specified period. In consequence, and engine's torque variation in time of shifting a car from decelerated running to accelerated running is absorbed and relieved by the sliding action of a torque converter so that the occurrence of discomfortable vibration can be checked.
Patent JP-S6162284-A (JP)
Title: Solid state image pick-up element
Inventor: IWADE SHUHEI
IPC: H04N5/335
Filed: 1984-09-03
Abstract: PURPOSE:To improve sensitivity and to make signal processing easy at the external part by connecting three bipolar transistors, two resistors and two switches mutually, amplifying voltage differentially by a light signal and taking out an amplified voltage signal. CONSTITUTION:When the first switch S1 is closed, a power source terminal 5 is connected and the second switch S2 is opened in Fig. (a), a voltage between junction capacities CBC becomes VCC-Vrefi and a stored charge quantity becomes CBC (VCC-Vrefi). When the first switch S1 is connected to the power source terminal 5 from a condition of Fig. (e), an electric potential of a terminal 7 becomes a formula 1 and becomes higher than the electric potential of an input terminal 3. At this time, when a current change is DELTAI2, an electric potential of an output terminal 4 becomes VCC-R1 (I2-DELTAI2). Consequently, the voltage change for R1XI2 only occurs at the output terminal 4. Since the current of the DELTAIx2 is amplified by an amplifying ratio hfe of the second transistor T2, the voltage change becomes much larger compared with the conventional method.

Abstract: PURPOSE:To reduce the number of part items in casting so as to reduce the weight of a device by forming an outer frame of a metal plate. CONSTITUTION:When a brake pedal is operated, an inner frame 14 moves to the opposite side to the disc rotor 12 side while being guided by a slide pin, and the lining 30 of an opposed outer pad 16 is pressed to the other side face of the disc rotor 12 to start braking action.

Thus produced secondary ions enter the mass-analyzing part 6, in which they are subjected to mass spectrometry immediately. After that, the data of the mass spectrometry are analyzed in a data analyzer.

Title: Discrimination system for chip name
Inventor: TAKAHATA SUNAO
IPC: G01R31/28
Filed: 1986-08-07
Abstract: PURPOSE:To eliminate wasteful time required for retrying a circuit test, a defective analysis, etc., of an integrated circuit by discriminating whether chip identification information corresponding to a test pattern is proper or not. CONSTITUTION:When a shift operation control signal 106 is '0', a bidirectional buffers 5 transmits an input signal 105 inputted from a bidirectional terminal 10. At this time, a scan-path type FF circuit group does not perform shifting operation and functions as the integrated circuit originally. When a circuit test is conducted by placing this FF circuit group in shifting operation, the name correspondence between chips and test patterns required for circuit tests is confirmed and the signal 106 is held at '1'; and chip name decision pattern signals 100-103 intrinsic to integrated circuits are inputted from a scan-in terminal 8 to perform shifting operation in synchronization with a clock, thereby setting them in FF circuits 1-4. Those signals 100-103 are inputted to a chip name discrimination pattern circuit 6 to generate a chip name discrimination signal 104, which is outputted from the buffer 5 to a terminal 10, thereby easily deciding whether a chip and a test pattern are comformable to each other properly or not.
