Title: Waveform measuring system
Inventor: MIZOMOTO HIROYUKI
IPC: G01R29/02
Filed: 1989-11-27
Abstract: PURPOSE:To judge a transmission pulse waveform at high speed by mounting a clock generating circuit, two waveform forming circuits, a subtractor comparing a reference sample signal with a sample signal to be measured to issue a sample error signal and a switch circuit. CONSTITUTION:A clock generating circuit 2 sends out the same clock signals Va having same phase to waveform forming circuits 4-1, 4-2 and a control signal generating circuit 8. The circuit 4-1 sends out a reference sample signal Vb to a subtractor 6 on the basis of the signal Va while the circuit 4-2 sends out a sample signal Vc to be measured. The subtractor 6 performs subtraction of the amplitudes between the signals Vb, Vc and sends out a sample error signal Vd to switch circuit 10-1 - 10-3. The control signal generating circuit 8 sends out control signals phi1 - phi3 controlling the circuits 10-1 - 10-3 on the basis of the signal Va. The circuits 10-1 - 10-3 send out the signal Vd to peak holding circuits 12-1 - 12-3 as output signals Vf1 - Vf3 during a period when the signal phi1 - phi3 have high level. The circuits 12-1 - 12-3 send out the max. value of the error voltage of the signals Vf1 - Vf3 to voltage measuring circuits 14-1 - 14-3 as output signals Vg1 - Vg3.

Title: Punch
Inventor: MORI CHUZO
IPC: B26F1/36
Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To punch holes by a lower edge and a blade edge and omit a pad by facilitating replacement of a cylindrical edge, and preventing influence from being exerted on dislocation of the edge tip of the cylindrical edge even if looseness exists more or less on a guide surface of a slider. SOLUTION: A holder 28 where a cylindrical edge 14 is inserted into through holes 25 and 26 bored in an upper horizontal part 22 and a lower horizontal part 23, is made to be taken in and out under a slider 10. Therefore, the cylindrical edge 14 can be replaced by a simple procedure such as the holder 28 is taken in and out. Since a vertical movement of the cylindrical edge 14 is guided by the through hole 25 bored in the upper horizontal part 22 regardless of a guide part of the slider 10, looseness is allowed for the guide part of the slider 10. A drift of the cylindrical edge 14 is eliminated, and since a lowering position of the edge tip is made accurate, paper can be cut between the edge tip of the cylindrical edge 14 and a lower edge 27, so that a pad can be omitted.

Title: Printer
Inventor: YAMAGUCHI MASAYUKI
IPC: B41J11/42
Filed: 1987-12-01
Abstract: PURPOSE:To correct an error in a paper drawing-in quantity inherent in a printer due to variations in a paper sensor or a mechanism part and maintain an optimum drawing-in quantity according to a format of a paper, by storing an optimum paper drawing-in quantity set by the operator through operating a minute line feed switch into an electrically erasable programmable memory (EEPROM). CONSTITUTION:After a paper is drawn-in, the operator moves the paper to an optimum head exposure position by a forward minute paper feed switch 1a and a backward minute paper feed switch 1b provided on a console panel 1. Next, with a paper drawing-in quantity determining switch 1c depressed, a controlling part 2 writes the paper drawing-in quantity corrected by the operator into an EEPROM 4. At the subsequent drawing-in of a paper, the controlling part 2 starts a motor-controlling part 3 according to the written value, thereby rotating a paper-feeding motor 5. By this operation, a printer is always made capable of drawing-in a paper to the optimum position set through correction by the operator, the set value being held in the EEPROM 4 even after a power supply is switched OFF.

Abstract: PURPOSE: To produce a member in which a wear resistant film is formed with superior adhesion on the surface of a milling tool, etc., by forming an (Al, Ti) (N, C) wear resistant film having respectively specified composition and thickness on the surface of a base material. CONSTITUTION: This wear resistant film coated member can be produced by forming a wear resistant film having a chemical composition represented by (Alx , Ti1-x ) (Ny , C1-y ) and also having 0.8-10μm film thickness on the surface of a base material, where 0.56<=x<=0.75 and 0.6<=y<=1 are satisfied. These component ranges are within the compositional range having NaCl type (B1 structure), and this film is an ALN solid solution into which TiN is allowed to enter by 25-44 mole %. When Al layer (x) exceeds the upper limit, the film composition becomes approximate to AlN, and as a result, the film is softened and sufficient hardness cannot be obtained and flank wear becomes liable to occur. On the other hand, when (x) is below the lower limit, oxidation starting temp. becomes <=800 deg.C.  Hardness is increased and wear resistance is improved with the decrease in (y) but oxidation resistance is deteriorated and crator wear becomes liable to occur when it is below the lower limit.

Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To reduce static electricity generated on a tool attaching shaft, and prevent damage on an electric component which may easily be caused by static electricity by composing bellows which cover the vertically moving tool attaching shaft of an articulated clean robot used in a clean room of electroconductive material. SOLUTION: When a motor 16 attached to an arm 17 of a robot is rotated, a ball screw nut 20 of a ball screw spline 7 is rotated through a timing belt 15. A spline shaft 21 is thus vertically moved. A bellows holder 22 attached to the spline shaft 21 is interlocked therewith, while charge preventing ballows 6a, 6a attached thereto are interlockingly moved vertically. Static electricity may occur at the surface at this time. Surface specific resistance values of the bellows 6a, 6a are, however, very small and they are connected to a grounding terminal 3. Static electricity is eliminated through an exclusive grounding line to suppress static electricity voltage.
