Title: Ic card
Inventor: HORIBA YASUHIRO
IPC: G06K19/00
Filed: 1987-10-30
Abstract: PURPOSE: To prevent the cutting of a wire and the breakdown of an IC chip from occurring and thereby enhance the reliability by arranging the elastic form at least, at one spot in a joint between an IC module embedded in a card base material and a card. CONSTITUTION: An IC module is arranged in a card base material made up of a laminate of center cores 15a, 15b and oversheets 14a, 14b and an elastic form 16 is formed in a joint between the IC module and the card base material. The shape of the elastic form 16 is optional, i.e., it is of such a shape as to cover only the outer periphery of the IC module or the entire face of the IC module excepting the external connecting terminal face side. In addition, the number of the pieces of the elastic form 16 to be used is also optional, i.e., whether it is a single piece or plural pieces. The material for the elastic form 16 is to be of high elasticity such as isoprene rubber, butadiene rubber, silicone rubber and the like.  Thus it is possible to prevent the IC module from becoming curved and also prevent the cutting of a wire connecting the IC chip 20 with a printed circuit board for the IC card and the breakdown of the IC chip itself from occurring.

Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To secure reliability in operation and return-to-zero by freely attaching/detaching a roller part to a switch cam added to a most significant digit gear by fixing a disk-shaped permanent magnet between respective digit gears and between the inner surface of a casing and the switch cam. SOLUTION: Concerning such a counter, digit gears 2 and 3 for respective digits can maintain a zero point in a state free from external force with a disk-shaped permanent magnet 7 fixed on a casing 1 corresponding to the attraction/repulsion of respective disk-shaped permanent magnets 6. Then, the digit gear 2 on a first stage is rotated by transmitting the rotation of a driving shaft 10-1 through a driving gear 10 to that gear 2 and the rotation is transmitted through a carry gear 4 to the digit gear 2 on a second stage soon. Besides, when resetting the counter, an actuator 11 is moved upward and when a microswitch 9, roller 9-1 and carry gear shaft 4-1 are pulled up to a switch cam 8, the carry gear 4 can be freely rotated away from the respective digit gears 2 and 3 so that all the digit gears can be returned to the position of '0'.

Title: Engine knocking sensing method
Inventor: KANAI HIROSHI
IPC: F02P5/152
Filed: 1990-10-16
Abstract: PURPOSE:To extract knocking distinctly even at the time of low S/N value without requiring alteration of the specifications, which should be applicable even for different engines, by calculating the running mean powers for each narrow frequency band of a plurality of channels on the time series basis. CONSTITUTION:The sensed wave-form of vibration or sound emitted from an engine is A/D converted, and high speed Fourie transform for narrow frequency of eight channels is performed in each of the sequentially appearing time divisions consisting of 16 points in such a way that the division is dislocated one after another, and the amplitude of the obtained narrow frequency band component is subjected to square processing to calculate the power of each. The result is subjected to running mean process on the time basis, and thus low pass filtering (smoothening) is made. Knocking can be sensed with improved S/N from this low pass filtering result or the result from subjecting it to synch. addition mean process. This permits knowing how the knocking can be sensed destictly by the use of the processing result of vibration or sound having a specific frequency at a specific crank angle.

Title: Optical receiver with signal interruption detection function
Inventor: FUKUOKA TAKASHI
IPC: H04B10/079
Filed: 1989-10-26
Abstract: PURPOSE:To attain sure operation with simple constitution by employing a comparator having two threshold levels and outputting an output signal when an input signal level exists between a couple of the threshold levels so as to detect the signal. CONSTITUTION:A 1st comparator 13 is a comparator waveform-shaping a reception signal and comparing a prescribed threshold level with an input signal to output a reproduction signal. On the other hand, a signal interrupt detection circuit consists of a 2nd comparator 14, a low pass filter 15 connecting to the output of the comparator 14, and a 3rd comparator 16 connecting to the output of the low pass filter 15. The 2nd comparator 14 has two threshold levels with a center level of an input signal in-between and outputs an output signal to detect the signal only when the input signal exits between a couple of the threshold levels. Thus, the intermission of the reception signal is surely detected with simple constitution.

Title: Motor driven expansion valve
Inventor: HIBINO YOZO
IPC: F16K31/04
Filed: 1990-10-19
Abstract: PURPOSE:To enhance the reliability and durability of a motor-driven expansion valve, which moves the shaft with a motor and adjusts the rate of medium flow through changing of the distance of the needle at the shaft tip from a needle seat, by installing a checking body on the medium inlet side for the shaft, and thereby smoothening motion of the shaft. CONSTITUTION:A checking body 11 is installed on the medium inlet side for a shaft 6, wherein the checking body 11 is formed columar thinner than the shaft 6 and the two ends are secured to the body 2 so as to be in parallel with the shaft 6. When medium flows in from an inlet joint 9, the medium runs first against the checking body 11, and not directly contacts the shaft 6, so that the fluid force is weakened. Therefore, the shaft is never put in eccentricity by the fluid force, and fit of a needle 7 with a seat 8 is kept constant, which smoothens the motion of the needle. Because this checking body 11 smoothens eventual ununiform input such as rippled flow or impact wave into a uniform steady wave, the medium passing through the gap between the needle 7 and seat 8 becomes uniform both in terms of time axis and the space, and the expanding action of the medium is stabilized.
