Title: Multiplier
Inventor: TSUTSUI TAKEO
IPC: G06F7/52
Filed: 1988-02-12
Abstract: PURPOSE:To obtain prescribed multiplication precision with a small-scale circuit constitution by detecting mantissa data and index values from respective input signals of bits in a fixed-point system, converting them into signals in a floating point system, multiplying both mantissa data, and bit-shifting the multiplied result by the sum of the index values of respective input signals. CONSTITUTION:Mantissa data are respectively extracted from respective input signals A and B of (i) bit and (j) bit in the fixed-point system by using mantissa data extraction circuits 11 and 13, and index value extraction circuits 12 and 14 extract the index values and convert them into the signals in the floating point system. At that time, the circuits 11 and 13 output only data of high-order '0' bit, which s necessary for assuring multiplication precision and a multiplication circuit 15 multiplies mantissa data of respective input signals A and B. Only data of high-order '0' bit in the multiplication result is outputted. Thus, same operation precision is held before and after the input and output of the circuit 15 and an operation output is inputted to a bit shift circuit 17. Thus, the result C of (m) bit (m>=l) in the fixed-point system in which prescribed multiplication precision is assured is obtained.

IPC: H03M1/78
Filed: 1992-02-18
Abstract: PURPOSE:To provide the linear interpolation system in which no gain is changed even when the length of a sample period is changed. CONSTITUTION:A sample-and-hold circuit 2 holds an input signal sampled for a prescribed period and generates an output changing stepwise. The output signal is delayed by one sample period from a delay circuit 3, and an output change is obtained by a subtractor circuit 4. An integration circuit 6 integrates an output of the subtractor circuit 4 and converts the signal changing stepwise into a triangle signal obtained by tying each sampling point of time with a line segment. When the sample period is changed, a gradient of the output of the integration circuit 6 is constant and the integration time is changed, the amplitude of the output of the integration circuit, that is, the gain is changed. A gain compensation means 7 changes a time constant of the integration circuit, a gain of the subtractor circuit or a gain of a variable gain circuit 5 added separately or the like depending on the sample period to compensate the gain change.

Title: Color signal processing method
Inventor: KATOU ASAKO
IPC: H04N9/64
Filed: 1994-02-02
Abstract: PURPOSE:To eliminate errors in the final stage of color signal data. CONSTITUTION:An LUT (look-up table) 4 outputs interpolation coefficients (K1, K2, K3) and main data (Co, Mo, Yo) converted into color signals corresponding to the colors of a second color system corresponding to the data of upper four bits in the color signal data of a first color system. An arithmetic part 5 generates interpolation data (c', m', y') by the data R1, G1 and B1 of lower four bits and the interpolation coefficients. The main data and the interpolation data are added by adders 6-8 and the data Cout, Mout and Yout are outputted. Since the main data of the final stage become 15 gradations, the interpolation data are obtained by the interpolation coefficient for which the interpolation coefficient obtained in 16 gradations is multiplied by 16/15 only in the final stage.

Title: Camera provided with cartridge cover
Inventor: SUZUKA SHINYA
IPC: G03B17/28
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To prevent a light shielding door driving means for opening/closing the light shielding door of a cartridge from being driven or operated, when a cartridge cover is opened by providing the light shielding door driving means and a locking means. SOLUTION: In a state where the locking of the cartridge cover is released, a locking pawl 55 is located to attain engagement with a slide lever locking pawl 75. When the cartridge cover is turned in an opening direction, in the released state of locking, the top end part 73 of a locking lever 71 is released from a peripheral wall 27 and projected by the energizing force of a spring 77. In other words, the slide lever locking pawl 75 of the lever 71 is engaged with the locking pawl 55 of a lever 51, to lock it at a light shielding door closing position. In this locking state, a door driver 41 can not be turned, so that while the cartridge cover is opened, a light shielding door driving lever 42 is never turned from the light shielding door closing position.  Thus, at the time of closing the cartridge cover, the door driver 41 is surely engaged with a connecting part, so that the driver 41 and the connecting part are never damaged.
Patent JP-S56128024-A (JP)
Title: Frequency divider
Inventor: ICHIDA KENJI
IPC: H03K23/58
Filed: 1980-03-12
Abstract: PURPOSE:To obtain a high-speed characteristic by means of a simple circuit configuration, by correcting so that a frequency dividing circuit outputs a data which is equal to a frequency dividing value data, in case when an output data of the frequency dividing circuit to which the frequency dividing data is provided is different from the frequency dividing data. CONSTITUTION:In case when the frequency dividing circuits 20-80 of the second stage and thereafter are set to a state ''1'', when the output of the inverter 33 is in ''1'' level, that is to say, when it is inhibited to input a preset data, an input signal which rises to ''1'' level is applied to the frequency dividing circuit 20. When a state of the frequency divider is 10,000,000, the output of the inverter 33 becomes ''0'' level, therefore, when a preset signal is inputted at that time, the contents of only a counter in which a preset data is positioned at ''0'' are corrected to ''0'', and as a result, a normal preset data N value is set. In this way, since only a frequency dividing circuit which is in a down-counted state is corrected, a high speed characteristic can be obtained.

Abstract: PURPOSE:To restrict the fluctuation of a resonance frequency by providing a lead-in passage for leading the coolant into passages built-in electrodes, communicating passages for communicating the passages built-in the electrodes, a lead-out passage for leading the coolant out of the passages built-in the electrodes inside of electrode supporting members. CONSTITUTION:Since passages 1a-1d built in each electrode are communicated with each other by communicating passages 2a-2d, 3e formed in posts 2A-2D and a base 3A, all of electrodes IA-ID can be cooled by a lead-in pipe 4A and a lead-out pipe 48. Furthermore, since the coolant C is flowed not only in the passages 1a-1d built-in the electrodes but also in the posts 2A-2D and th base 3A, the posts 2A-2D and the base 3A are cooled with the coolant C to restrict a rise of temperature of the posts 2A-2D and the base 3A. The fluctuation of a resonance frequency can be thereby reduced.

Title: Detecting device for welding part of metallic material
Inventor: TANAKA AKIHIRO
IPC: G01N29/48
Filed: 1981-03-06
Abstract: PURPOSE:To detect a welding part on a basis of the attenuation quantity of ultrasonic waves propageted in a metallic material, by generating ultrasonic waves in the metallic material by an electromagnetic force. CONSTITUTION:An exciting coil 11 of probes 3A and 3B is excited by a DC power source 4 to apply a DC magnetic field to a steel pipe 1. When a pulse current is given to a transmitting and receiving coil 12 from a pulse generating circuit 5, an eddy current is generated on the surface of the steel pipe 1 by a changing magnetic field. The changing distortion on the outside face of a steel pipe 1 due to the interaction of DC magnetic fields is propagated as ultrasonic waves toward the bottom face. When the reflection wave from the inside face reaches the outside face, an eddy current is generated by the interaction between the reflection wave and the DC magnetic field. An alteration magnetic field due to this eddy current is detected by the transmitting and receiving coil 12. Detection signals of probes 3A and 3B are outputted to the transmitting and receiving coil 12 and are amplified by amplifiers 6A and 6B and are applied to a subtracting circuit 7. The output of the subtracting circuit 7 is given to a comparing circuit 8; and when the difference signal becomes a set value level, an output is generated to drive a relay circuit 9.

Title: Ignition timing control device
Inventor: KANETOSHI KAZUHIKO
IPC: F02P5/153
Filed: 1986-02-14
Abstract: PURPOSE:To enable shortening of a time in which an advancing angle is increased to a demand value, by a method wherein, during an advancing angle when no knocking occurs, an advancing angle speed, at which an ignition timing is finely advanced according to a change rate of a load, is increased. CONSTITUTION:When, in a control circuit 19, it is decided from an output from a knocking sensor 18 that knocking is present, a fine delay angle amount is added to the correction delay angle amount of an ignition timing to prevent the occurrence of knocking. In which case, when the opening of a throttle is suddenly changed and it is decided that reduction is in progress, the degree of reduction is discriminated by a load state detecting means 17. When no knocking occurs, a fine advancing angle amount determined according to the degree of reduction is deducted from a correction advancing angle. Thus, since a time in which an advancing angle is increased to a demand value depending upon a change rate of a load is shortened, fuel consumption and drivability are further improved.
