IPC: G06F17/16
Filed: 1983-03-25
Abstract: PURPOSE:To eliminate the necessity of making overflow processing by means of software at every calculation so as to reduce a processing time by automatically writing the maximum or minimum value instead of an operation result in accordance with the presence or absence of carry when the operation result overflows. CONSTITUTION:A sequencer SEQ1 which controls the whole system is connected to a common signal line BUS and an RAM2 is also connected to the BUS, and then, the BUS is conntected to the input terminal (a) of a multiplying circuit 4. On the other hand, an ROM3 is connected to the other terminal (b) of the circuit 4. One input terminal (d) of an operational logical circuit 5 is connected to the output of the circuit 4 and the other input terminal (c) is connected to a temporary storage circuit 6. When overflow occurs as a result of addition of the output (c) of the circuit 6 and the output (d) of the circuit 4, the negative maximum value and, when no carry occurs, the positive maximum value is automatically written in a register 7. When overflow processing is made in such a way, the value is maintained until data are read out to the BUS from the register 7.

Filed: 1980-04-16
Abstract: PURPOSE:To uniformly heat objects to be heated such as large wire rod coils by circulating the hot wind to be blown to the objects to be heated in opposite directions by each zone, in a continuous furnace. CONSTITUTION:In a continuous furnace such as roller hearth furnace, the agitating fans 5a, 5c of zones A, C form a circulation system of blowing the hot wind to the objects 3a, 3c to be heated of each zone from above, allowing the same to flow downward and turning it upward in the lower part of rollers 2 for transfer.

IPC: G11B3/085
Filed: 1978-04-28
Abstract: PURPOSE: To improve operating characteristic by reversing the running of a motor which rotates a control cam leading-in a tone arm to a forward moving state by a changeover means when the arm is set on a record disc by hand and reject operation is done.  
     CONSTITUTION: An a motor runs forward, a control cam 6 rotates forward in a clockwise direction, causing a tone arm revolving shaft to make lead-in and descend the arm. As it runs backward, the arm is returned to the rest position. Position- detecting SW 1  thru SW 3  are provided along the outside circumference of the cam 6 and are subsequently operated by the protrusion 18 of the cam. When the cam 6 is in a stop state, the protrusion 18 pushes the SW 1  and contacts its traveling contact 28 to a fixed contact 28b. FFs 21, 25 are then respectively reset via C 1 , C 2  by a +B power source to prevent forward and backward driving circuits 22, 26 from operating, and the motor 3 is not running. When a reject switch 23 is pushed after manual lead-in, the FF 21 is set and the motor 3 is run forward by the circuit 22. When SW 2  is next operated, the FF 25 is set via AND circuit 24 to run the motor 3 backward.

Abstract: PURPOSE:To make it possible to form easily a high-speed IC D/A converter by improving the structure of elements forming a current switch. CONSTITUTION:Constant-current sources 111-118 are connected to input terminals 41-48 of current switches 11-18 having digital input terminals 1-8. Respective switches 11-18 are formed as differential two-stage amplifier consisting of a pair of NPN transistors, where emitters are connected commonly into input terminals 41- 48, and a pair of PNP transistors where emitters are connected commonly. PNP transistors are formed with the vertical PNP structure on the same semiconductor substrate. By this vertical PNP structure, the cut-off frequency is enhanced, so that the switching speed of current switches can be high. Thus, a high-speed IC D/A converter can be formed easily without a special process.

Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To position and bond a pellet to a bonding position of a substrate at high speed with high accuracy by correcting misalignment in the rotational direction of the substrate on a bonding stage through rotation of the pellet on a preciser stage. SOLUTION: A preciser stage 13 mounts a pellet 3 taken out from a pellet transfer 21 onto a rotary table 23 and detects the position of the pellet 3 on the rotary table 23 in the rotational direction and XY direction by means of a camera 24. Based on the detection results, misalignment of the preciser stage 13 from the referential position in the rotational direction of the pellet 3 on the rotary table 23 is corrected through rotation of the pellet 3 caused by rotation of the rotary table 23 thus correcting position in the rotational direction of the pellet 3.

Title: Dictionary registering method
Inventor: NEMOTO SHIORI
IPC: G06F17/22
Filed: 1988-03-04
Abstract: PURPOSE:To obtain a dictionary having excellent usability by adding and registering a technical term priority flag concerning whether or not the technical term is preferentially converted to the general terms of homophones to the respective words in the technical term dictionary. CONSTITUTION:For example, a case A is the homophone in which the technical term is preferentially converted to the general term, a case B is the one in which the general term is preferentially converted to the technical term, and a case C is the special technical term in which the general term is preferentially converted to the technical term, and for the homophone belonging to the case A, a 'U' is set at the preferential flag of the technical term, and for the one belonging to the case B, the preferential flag of the technical term is idle, whereas, the column of a frequency is set at 'O'. For the one belonging to the case C, a 'D' is set at the preferential flag of the technical term. That is, when the 'U' is added as the preferential flag, the word is shifted to the record of the highest-order of the homophone, on the contrary, when the 'D' is added as the preferential flag, the word is shifted to the record of the lowest-order of the homophone. Thus, the homophone can be easily converted to more proper term either of the general term or the technical term.
