Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To prevent document setting errors by providing a document detecting device capable of detecting the size and set condition (movement, etc.) of a document placed on a document stand. SOLUTION: This document detecting device is provided with an angle detecting means 7 for detecting the angle by which a document holding plate 6 pressing a document 5 on a document stand 4 is closed, with a detecting means 1 for detecting a document end position and with a control means 10. The detecting means 1 is constituted of an illumination means 2, having a light emitting part placed below the document stand 4 and a lens provided at the front of the light emitting part, and emitting the light from the light emitting part toward the document stand 4 while converting the light into a parallel beam by means of the lens, and of a light receiving means 3 comprising one lens for receiving the light reflected from the document 5 illuminated by the illumination means 2 and one photocell. The control means 10 operates the detecting means 1 when the angle by which the document holding plate 6 is closed comes into a predetermined area, a signal from the angle detecting means 7 and detects position and size of the document 5 by comparing a signal output from the detecting means 1 with contents prestored in a storage means.

Title: Polarity detecting circuit for direct current superposed ringing signal
Inventor: SUZUKI HIDEHIKO
IPC: H04Q5/02
Filed: 1987-09-24
Abstract: PURPOSE:To detect the polarity of a DC component in about one cycle of a ringing signal by deciding whether the sum of a positive maximum value and a negative maximum value is plus or minus and supplying the polarity decision result at a zero-cross point. CONSTITUTION:When the ringing signal 11 is inputted, the output 13 of a positive maximum value holding circuit 1 indicates the positive maximum value of the ringing signal 11 and the output 14 of a negative maximum value holding circuit 2 indicates the negative maximum value of the ringing signal 11. Those outputs 13 and 14 are summed up by an adder 4. A positive edge zero-cross detecting circuit 13 rises at a zero-cross point when the ringing signal 11 values from negative to positive, and a positive edge zero-cross pulse 12 with narrow pulse width which rises soon is generated. The value of the sum signal 15 right before that is in proportion to the mean value of the ringing signal 11, so a comparator 5 decides whether the signal is positive or minus and its output 18 is latched by a D flip-flop 6 with a positive edge zero-cross pulse 12. Consequently, the polarity of the DC component of the ringing signal 11 is represented as the level of the output 17 of the D flip-flop 6.

Filed: 1989-09-18
Abstract: PURPOSE: To determine the most suitable starting point of a cruciform ligament at the femur and the tibia, to finish femur and tibia tunnels, and to support the ligament at the tunnels with tension force by attaching a suture material with tension force, and attaching a tension isometry measuring device to measure changes of tension when the knee is bent in all the range of movement. CONSTITUTION: A stud 19 and driver 20 are guided by a surgeon to the spot on the femur where the top of a drill 21 strikes and the surgeon believes to be a starting point of isometry on the femur. Next, the stud 19 is carefully screwed into the bone, then the driver 20 is carefully pulled out of the stud 19, while a suture material 24 is remained inside the stud 19, extending from inside the stud 19. So the suture material 24 is pulled by the driver 20 to the outside of a tibia tunnel 18. In order to decide whether the edge of the tibia tunnel 18 and the selected point on the femur are really points of isometry, an artificial ligament, that is the edge of the suture material 24, is connected to a tension isometry measuring device under appropriate tension.  When previously a prescribed load is given on a scale of the tension isometry measuring device, the knee, will be bent at various angles, and the force applied at each angel will be measured.

Title: Electron beam generator for electron beam measuring equipment
Inventor: BURUKUHARUTO RISHIYUKE
IPC: H01J37/07
Filed: 1988-09-26
Abstract: PURPOSE: To improve thermal and mechanical characteristics, and lengthen the service life of a boride cathode by arranging a cathode holder member just under an electron emitting area of the cathode. CONSTITUTION: A boride cathode BK is arranged in an opening part area of a control electrode W where a negative bias is imposed on the cathode BK by a holder H. The holder H has two adjusting screws S and a fastener composed of two metallic fastening members K. This fastener imparts holding power made by the adjusting screws S to both graphite cubes G arranged just under a pointed tip part of an LaB6 crystal. Heating power to put the cathode BK at a necessary operation temperature may be little by such holding. An LaB6 crystal in a fastening plane does not become remarkably hotter than an LaB6 crystal of an electron emitting pointed tip part. Therefore, an evaporation rate of a crystal surface reduces.
