Abstract: PURPOSE:To recognize the number of copies at every identification (ID) code by a simple constitution and operation without adding a specific device by counting up the number of copies at every ID code and displaying the number of copies in accordance with a command from a commanding means. CONSTITUTION:The display of an ID counter is switched to ID counting display at every depression of an ID count key 30f on a console panel 30 independently of the current display status of a display device 30o. In case of copying operation using ID numbers, the number of copies is counted by a control part 51 at every ID number, and at the depression of the key 30f, the total number of copies and the number of copies at every ID number are simultaneously displayed on the display unit 30o. Thereby, the number of copies at every ID number and the total number of copies can be simultaneously displayed without adding a specific device and the number of copies can be easily recognized. Since the number of copies is displayed by the operation of only the key 30f, the operation is made easy.

Title: Evaluation of mos device
Inventor: OTSUKI TAKESHI
IPC: G01R31/302
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To specify the points of defects and observe defective regions by detecting changeable defects of a MOS device formed on a silicon wafer which change with the passage of time, using optical or electron induction current (OBIC or EBIC). SOLUTION: A sample wafer 13 is set in a scanning electron microscope system(SEM) 16, with the rear face side grounded and the gate electrode side connected to a DC power supply 11 through a probe 10. If a carrier is injected into the wafer which is scanned by and irradiated with an electron beam 17, the depth for the optimum carrier injection efficiency is different, depending on the acceleration voltage. When a MOS device is a P type, strong EBIC is observed from the MOS device if the application voltage is increased in the positive direction (in the case of N type, the direction is negative). This very small current is amplified by a current amplifier 18, and then the data about the current and the information about electron beam irradiating positions are combined to display the images of the defects on a CRT 19.  By this method, the defective points can be discriminated from the normal points and the EBIC images can be observed.

Title: High-efficiency coding/decoding device
IPC: H04N19/577
Filed: 1992-03-25
Abstract: PURPOSE:To improve the picture quality of regenerative images at the time of special reproducing. CONSTITUTION:A low compressibility circuit 81 processes input video signals at low compressibility, and a high compressibility circuit 83 processes input video signals at high compressibility. The low compressibility processed signals and high compressibility processed signals are respectively added to a low compression flag and a high compression flag and supplied to a switch 86. A recording position deciding circuit 88 controls the switch 86 corresponding to track numbers. Thus, the high compressibility processed signals are outputted from the switch 86 at timing corresponding to a regenerative area at the time of special reproducing, and the low compressibility processed signals are outputted at the other timing. Since the high compressibility processed signals are decoded on the reproducing side at the time of special reproducing and one image is prepared by selecting one part of plural decoded outputs, the smooth regenerative image can be obtained.

Title: Pest repellent
Inventor: SUGIYAMA MASAFUMI
IPC: C08L101/16
Filed: 1994-03-11
Abstract: PURPOSE:To obtain a pest repellent, having high sustained release properties, capable of sustaining effects, nontoxic to plants, humans and livestock after eliminating the effects, gentle to the environment and readily moldable, processable and colorable, etc., at a low cost. CONSTITUTION:This pest repellent is obtained by adding 0.1-1,000 pts.wt. pest repellent ingredient to 100 pts.wt. unvulcanized natural rubber. The shape is retained by the unvulcanized natural rubber and the pest repellent ingredient is not discharged with rainwater, etc., at a stroke. Since the unvulcanized natural rubber is slowly degraded from the surface by ultraviolet rays or microorganisms in soil, effects are sustained and the sustained release properties of the repellent ingredient are high. The repellent ingredient disappears by biodegradation after eliminating the effects and degraded materials of the natural rubber are nontoxic to plants, humans and livestock without remaining in soil. Thereby, the repellent is so-called gentle to the environment without polluting or disrupting the environment including the plants. Furthermore, a repellent unstable to heat can be added without requiring the thermal melting of the unvulcanized natural rubber as opposed to the case of other biodegradable resins in adding the repellent.
