Title: Optical scanner
Inventor: SHIMIZU TAKUMI
IPC: G02B7/00
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To provide an easily decomposable optical scanner excellent for a re-cyclable property. SOLUTION: Optical parts such as an fθ lens 42, etc., arranged in an optical box 46 in the optical scanner are pressurized and held by hold members 50, and are fixed by a wire 52 and a tensioner. That is, by adjusting tension applied to the wire 52 by the tensioner, the optical parts are fixed surely. Thus, the optical parts are taken off, and the optical scanner is decomposed only by performing simple work so as to weaken the tension applied to the wire 52. Further, since the parts aren't damaged at a decomposing time, respective parts are reused after cleaning, adjustment and exchange of consumption parts, etc., are performed, and the recyclable property is improved.

Title: Planetary gear type change gear
Inventor: KAMEDA OSAMU
IPC: F16H3/66
Filed: 1988-02-08
Abstract: PURPOSE:To select operating force lightly and smoothly by performing a changeover between direct drive and reduction radio drive with a shift fork, and reciprocating a sleeve. CONSTITUTION:When a selector sleeve is situated in a direct driving position, a spline 21c is engaged with a spline 17a. Therefore an output shaft 10A is rotated at a high speed mode. Next, when it is selected by a shaft fork 23 and transferred to a reduction ratio driving position with the selector sleeve 21 moved, a spline 20c is engaged with a spline 25a. Accordingly, the output shaft 10A is rotated at a low speed mode. Thus, a changeover between the high speed mode and the low speed mode can be done smoothly with light operating force.

Abstract: PROBLEM TO BE SOLVED: To execute radio communication from all the slave stations to a master station without installing a special repeater station by allowing the plural radio stations dotting within a fixed area to play the role of repeater stations so as to construct a transmitting line networked through a prescribed range. SOLUTION: When data communication is requested to a slave station 1I from the master station 2, the slave station 1I prepares a data signal for communication. At this time, a data signal including the address of a transmission destination slave station 1A of a higher priority order of two transmission destination slave stations 1A to 1C existing in a range capable of receiving a transmission radio wave is prepared. Then, after signal conversion, the two stations 1A and 1C are called. The two stations 1A and 1C respectively check an address in a transmission data signal and only the station 1A whose address is coincident with that of its own slave station and whose order is set to be high transmits a response signal to the station 1I. A communication link is established between both stations by this response.

Title: Arithmetic processor
Inventor: WATANABE TAKESHI
IPC: G06F9/308
Filed: 1983-02-23
Abstract: PURPOSE:To speed up zero detection and shorten the generation delay of a condition code by providing a mask which sets input data to zero forcibly according to an instruction type to the input of a computing element. CONSTITUTION:A selector A3 and a selector B4 compare in size the exponent parts of the 1st and the 2nd operands; the selector A3 selects a larger part and the selector B4 selects a smaller part. A pre-shifter 6 shifts the operand having the smaller exponent part to right on the basis of the difference in exponent part obtained from said comparison to match the digit to the operand having the larger exponent part. Masking 15 is performed at the final-stage gate of the pre-shifter 6, so there is no increase in the number of gates. The mask 15 functions to pass input data as it is at one-digit of a mask 1. Thus, the masking is performed to secure the masked part to 0. Therefore, a zero detector 16 only detects whether all digits are 0 or not.

Abstract: PURPOSE:To optimize the fan-out number or the drivability of a cell by performing the assignment of a logical cell to output a signal across functional blocks based on the fan-out number to satisfy its rule. CONSTITUTION:The functional block 10 gives its output to the functional blocks 11 and 12 of a following stage, and further, the output of the block 11 is fed back to its input. Individual input branch number at each input terminal is set beforehand for the blocks 10 to 12. Then, in the course of the generation of the logic circuit of the block 10, the assignment of internal cell is executed so that a designing rule such as a fan-in number or the fan-out number is satisfied. This acts upon the functional block of the object of logic generation so that dependency upon the actual logic of the functional block of a preceding stage or the following stage is eliminated. Thus, in logic designing by structurizing technique or hierarchizing technique, etc., the fan-out number or the drivability of the cell for outputting the signal across the functional blocks can be optimized.
