Title: Self-diagnostic device for on-vehicle meter
Inventor: HAYASHI TAKATOSHI
IPC: G01D18/00
Filed: 1987-07-03
Abstract: PURPOSE:To obtain a self-diagnostic device for an on-vehicle meter which operates accurately by generating and supplying a dummy measurement signal when a measurement signal reaches a 2nd voltage after a specific time is counted after the measurement signal reaches a 1st voltage. CONSTITUTION:When a vehicle speed sensor 1 is disconnected for a diagnosis by extracting connectors 21a and 21b, the output of an inverter 29 falls to low level and a 1st counter 33 beings to count. When the counter counts up to a specific value, a flip-flop 29 is set and its output puts an AND circuit 45 in a gate state to supply a reference clock to a 2nd counter 35, whose output is supplied to an AND circuit 37. The 2nd counter 35 begins to count the reference clock signal ck1 and when the vehicle speed sensor 1 is reconnected through the connectors 21a and 21b before the counter counts up to a specific value, the flip-flop 47 is set. Then an AND gate 53 is put in gate operation to supply a dummy vehicle speed SS to an OR circuit 27 and the signal is further supplied to a crossing coil type meter 33 through a crossing coil driving circuit 7.

Title: Frequency adjusting method for piezoelectric vibrator
Inventor: ONO MASAAKI
IPC: H03H3/04
Filed: 1986-07-15
Abstract: PURPOSE:To contrive to suppress the change in a static capacitance Cd and a capecitance ratio gamma by applying laser radiaton onto an electrode face so as to apply mesh spot trimming thereby attaining the trimming with respect to a decreasing frequency as well as an increasing frequency. CONSTITUTION:The mesh spot trimming is applied to the electrode face by using a laser to adjust the frequency. The frequency is adjusted in both increasing and decreasing directions by varying a trimming laser output as shown in figure A. The resonance frequency tends to increase as the laser output is increased as the result of experiment, but, on the other hand, the frequency has a decreasing tendency with further increase of the resonance frequency. That is, the resonance frequency is decreased proportional to number of spots with the mesh trimming at a large laser spot diameter, while the resonance frequency is increased proportional to the spot number with the trimming at a smaller spot diamter. Moreover, the static capacitance Cd and the capacitance ratio gamma are almost unchanged independenly of the trimming as shown in figures B and C.

Title: Automatic focusing device for camera
Inventor: IWANE TORU
IPC: G02B7/28
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To improve a tracking performance to a moving subject by statistically calculating an average detecting time, image surface position and image surface velocity, based on the defocusing amount of a photographing lens, its detecting time and the position of the lens, and further statistically calculating the image surface velocity and the image surface position at a predetermined time. SOLUTION: The defocusing amount is inputted from a defocusing amount detection device 3, and the position of the lens at this point and the time are inputted from a position detection device 2 and a clock 5. For instance, data from a present time to 300ms past is viewed in perspective to select the data. The result by statistical calculation is stored in a 2nd storage device 7. When the number of data exceeds a specified value, regression calculation is performed. The tilt of a positional regression expression is found as the change per unit time of the image surface velocity from the regression calculation. By performing the calculation including an intercept, the image surface velocity at a certain time is estimated.  Then, the image surface velocity optimum for focusing at exposure time and the defocusing amount at the present time are calculated, and the data is transmitted to a lens having driving ability so as to obtain focusing.

IPC: A63F7/02
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To prevent the inconvenience of discriminating the timing corresponding to a specific value from outside to the possible minimum level, and prevent an unfair practice performed by discriminating it on the outside to the possible minimum level by performing changing processing in a condition where its changing content cannot be discriminated from outside by a specific value corresponding time changing means. SOLUTION: Since so far a hit judging value is a specific value and an addition value of WC RND1 is uniform as 1, if a staring winning signal B is outputted to a game control base board 203 in the timing when a value of a counter in a signal work machine 202 becomes a predetermined hit judging value, in a moment when a count value of the WC RND1 of the game control base board 203 becomes the hit judging value, its count value is extracted on the basis of the starting winning signal B, and a big hit is surely generated. Then, corresponding time when the count value of the WC RND1 corresponds to a big hit judging value is changed by changing a judging value to the other value, and when the starting winning signal B from the signal work machine 202 is outputted, the count value is made noncorresponding.
