Title: Combined sleeve for driving caterpillar
Inventor: IIJIMA MASAYUKI
IPC: B62D55/21
Filed: 1982-07-19
Abstract: PURPOSE:To obtain a sleeve for driving a caterpillar with high durability against abrasion of earth and sand and repeated high load for a long time by combining a surface layer of sintered hard material to disperse particles above MHv 1,000 at an area rate above 15% on a contact face of a steel sleeve with a sprocket. CONSTITUTION:This sleeve is composed of a steel sleeve main body 1 and a surface layer 2 of sintered hard material in which hard particles with hardness above MHv 1,000 are dispersed at an area rate above 15% and the difference of coefficient of thermal expansion with the sleeve main body is within 0.3X10<-5>/ deg.C (only in the thermal range of 0-600 deg.C); the surface layer of the said sintered hard material is combined on a partial or the whole surface of the contact part of the sleeve main body with a sprocket for transmitting a drive power. When the hardness of the hard particles is under MHv 1,000 or the dispersion of the hard particles is under 15% area rate, the durability against abrasion of earth, wet sand, and the like is greatly reduced to loose the advantage to prolong the life of the sleeve for driving a caterpillar. When the difference of the thermal expansion coefficient between the sintered hard material and the sleeve main body surpasses 0.3X10<-5>/ deg.C, the cooling process after dispersing combination at high temperature and the cementation after the combination, or the contraction difference after hardening, cause cracking.

Title: Electronic copying machine provided with editing function
Inventor: MIZUTANI TAKETOMO
IPC: G06F3/048
Filed: 1986-05-29
Abstract: PURPOSE:To constitute the titled copying machine so that even a beginner can easily designate a position of an original to be edited, by incrementing or decrementing a counter means in accordance with the moving direction of a position designating means. CONSTITUTION:When a position designating means is moved on an original surface of an original, a moving extent is converted by, for instance, a pulse, etc. in accordance with the moving extent and counted by a count means. Also, in accordance with a moving direction of a position designating means, for instance, in accordance with advance or retreat of the position designating means, a count control means increments or decrements a count value of the counter means. When a position designation of the original is ended, the original is placed on an original platen and a copying button is operated. As a result, by an image forming means, a copy image which is edited (trimming, moving, etc.) in accordance with a count value, based on its count value of the count means is formed.

Abstract: PURPOSE:To obtain a waveform free from distortion, by slicing the signal distorted by passing through the transmission system of the TV or the like with a fixed slice level to secure the optimum level at all times and then digitizing the sliced signal. CONSTITUTION:The video wave detection output signal A passed through the transmission system is supplied to the slicing circuit 1, the synchronous isolating circuit 2 and the chrominance subcarrier isolating circuit 3 each. The horizontal synchronous signal H is isolated through the circuit 2, and the sampling gate signal B is formed by the gate generating circuit 4 to be supplied to the gate circuit 5. The static picture signal C is sampled out of the digital signal of the circuit 1 through the circuit 5 and via the signal B. At the same time, the clock generating circuit 7 supplies the signal nfsc obtained by n-multiplying the output of the circuit 3 as well as the signal H to produce the gate signal D to supply it to the gate circuit 8 and then to sample the clock line signal E. The signal E samples the signal nfsc to supply it to the gate circuit 9, thus producing the signal F. This signal receives the binary display after counted for its pulse duration in the counter 10 and by the vertical synchronous signal V. After this, the signal is turned into an analog form and then compared with the reference signal through the comparator 12 to produce the control signal to give a control to the slice level.
