Title: Amplifier for active filter
Inventor: HAGINO HIDEYUKI
IPC: H03F3/68
Filed: 1991-02-08
Abstract: PURPOSE:To obtain the amplifier for active filter which improves offset between input and output signals and suppresses the degradation of filter characteristics by providing independently a power source for every differential current amplifying stage. CONSTITUTION:This amplifier is independently provided with power supply parts 4a and 4b for respective differential current amplifying stages 1a and 1b. The power supply part 4a is constituted of a current mirror circuit for obtaining a output current corresponding to an input current. Therefore, since the output current of the power supply part 4a is supplied to the collector terminal of a transistor TrQ12a, the output current at a value set to the input current of the power supply part 4a is surely impressed to the first amplifying stage 1a. Thus, the collector currents of TrQ1a and Q2a are made equal, and the offset of an input/output signal potential in the amplifying stage 1a is suppressed. On the other hand, the next differential current amplifying stage 1b is made similar to the first differential current amplifying stage 1a as well. As a result, the offset between input and output signals is improved, and the degradation of filter characteristics is suppressed.

Title: Data processor
Inventor: NAKAKAWAJI NOZOMI
IPC: G06F3/037
Filed: 1988-01-28
Abstract: PURPOSE:To freely switch an optional input device so as to attain an operation and to attain the collective input of a pointing device by converting a pointing device input into an equal keyboard input. CONSTITUTION:An input output processing part 7 receives inputs from a keyboard 3 and the pointing device 4 and discriminates from which device the input comes from. When the input is from the pointing device 4, it is converted into the equivalent keyboard input, stored in the same input buffer as the input from the keyboard 3 and displayed on a display screen. When the input from the keyboard 3 or the point device 4 shows an execution trigger, a character string is segmented from the input buffer and a system is shifted to the execution of the processing. Thus, the free combination of the keyboard input and the pointing device input can be obtained and the collective input of the pointing device 4 is attained. Furthermore, the degree of freedom in the operation can be increased and the processing can be speeded up.

Then, ratios (COR/CO)D and (COR/CO)H are calculated, and the ratios (CO)D and (C/CO)H of the H 2  concentration (C)D decreased by a low-temperature after treatment to the residual H concentrations (CO)D and (CO)H of the welded metal and heat-influenced part are found. Then, a heat treatment is completed when the time integral value of a hydrogen diffusion coefficient at the temperature of an adequate position of the welded zone measured during after-treatment exceeds a prescribed value.

Abstract: PURPOSE: To provide a skipping number printer which blank-strikes unnecessary numbers while advancing numbers so as to print only necessary numbers by changing over the stroke lengths of the operating levers of numbering machines through  control valves.  
     CONSTITUTION: First, compressed air is alternately supplied to supply/discharge ports 50 and 51 of each cylinder 39 in cylinder driving mechanisms 37 and 38 to continuously cause each piston rod 40 to reciprocate vertically.

The character wheels of the machines 3 and 4 are rotated so that numbers advance one by one at each reciprocation. In this case, when printing, the wheels are pressed against a label to print with the first stroke, and when not printing, they are lowered with the second stroke shorter than the first and made to perform not printing but only advancing number. During said blank striking, a solenoid valves are controlled by position detectors 43 as well as the number of blank striking is counted to change-over the stroke.

Abstract: PURPOSE:To enable knowing of the direction of movement of a substance and the number of times thereof by discriminating a light-receiving body which is intercepted from the light first when the substance intercepts a pair of light-receiving bodies arranged very near to each other from the light. CONSTITUTION:When the substance advances in the direction of an arrow G, luminous flux emitted by a projector D is intercepted and a signal is delivered from the light recepter 21, amplified 31 and detected 51 through a filter 41, whereby an output is obtained. This output is inputted in the input terminal M1 of a foremost discrimination circuit 6 composed of a nonsynchronous type dual monostable multivibrator and in an inhibit terminal H2 which evades reception of a signal coming in one input terminal while the signal coming in the other input terminal is received, and a pulse output is generated in an output terminal Q1 alone. When the substance comes from the direction opposited to the arrow G, the pulse output is generated likewise only in Q2 from the output of a light receptor 22.

Title: Image printing device
Inventor: ENDO HIROYUKI
IPC: B41J2/44
Filed: 1990-01-31
Abstract: PURPOSE:To make possible the printing of high-quality characters and at the same time, obtain a halftone image of satisfactory quality by interpreting whether there can be a single line-wide linear component based on a relationship between the values of bits at the same digital positions of an output line and a line before or after the former, and determining a character area and a halftone image area based on the lengths of the lines. CONSTITUTION:A line width interpretation part 4 reads bits at the same digital positions from a line buffer aimed at an output 2, a front line buffer 1 and a back line buffer 3, and connects a signal to a line length interpretation part 8 based on a logic relationship between three bits. For example, if the bit of the line aimed at an output is 1, and the bits of the front and back lines are '0' respectively, bit '1' is output and in the other case, bit '0' is output. A line length interpretation part 8 counts so many continuous bits of '1', and if the length of a row of bits '1' is below a specified value, the part 8 sets the row of bits to '0', and outputs a signal for the bit '1' to an auxiliary LED signal generation part, if the length exceeds a specified value. Thus the character area and the halftone image area can be determined.

Abstract: PURPOSE:To prevent the generation of image shear by forming a transfer material carriage suppressing means in a resupply line to suppress the carriage of a resupplied transfer material to be carried to a transfer material synchronizing carrying means. CONSTITUTION:When interlocking operation of a horizontal resist lower roller 41 is executed, an output body 62 of a driving control spring clutch 61 connected to the roller 41 is also rotated. At that time, the outer periphery of a boss part of the output body 62 is rubbed with the inner periphery of a stopped clutch spring 65, resisting force is generated between them and slight load torque is generated in the output body 62. When the output body 62 is rotated, load is also generated in a resupplied transfer sheet and a pair of resist rollers 22 carry the resupplied transfer sheet against the load torque. Thereby, the carrying speed of the pair of resist rollers 22 is affected and slightly delayed and a transfer image contracted in accordance with the contraction of the transfer image due to the load torque of positive and negative rotation rollers generated in the 1st copying or the contraction of the transfer image due to a fixing part is formed on the resupplied transfer sheet. Consequently, a multiple copy image of high quality whose image shear is reduced can be obtained.
