Abstract: PURPOSE:To remove the clogged state of an oil filter by opening, when in starting the engine the ambient temperature is so low that a frozen drain is produced, the opening/closing valve, introducing into a dryer a high temperature compressed air discharged from an air compressor, and thereby heating the oil filter section. CONSTITUTION:When a switch contactor 71 of a keyswitch 7 is changed over to a contact 7B against the ambient temperature which causes a freezing of water attachments on the oil filter of a compressed air dryer 2, since a temperature switch 8 is kept 'ON', power is supplied to a heater 9 and thus a drain section 2D is heated by a heat generated from a heater 9. Then, when the switch contactor 71 is turned to a contact 7C position in order to start the engine, an electromagnetic valve 6 is energized through operation of a controller 10, so that an inlet port 6B is changed over and connected to an outlet port 6C. Thereby, the compressed air in an air reservoir 4 is supplied to a control port 2E of the drain section 2D to open an opening/closing valve of the drain section 2D. And the oil filter FIL is heated by the compressed air which has flown into the drying device 2 and, as a result, the frozen drain is defrozen or decomposed.

Title: Automatic wiring method for semiconductor device, and semiconductor device
Inventor: KATO NAOKI
IPC: H01L21/82
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To decrease the frequency of remanufacturing of a semiconductor device, and shorten the manufacture period and reduce a cost by finding a terminal couple which do not use a top layer on an existent wiring path to sufficient length for machining before partial areas are wired and searching for a path which uses the top layer preferentially when the terminal couple are wired. SOLUTION: A rough wiring process 101 determines rough paths as to all nets. Here, only passing positions on the sides of the partial areas are determined and detailed paths in the partial areas are determined by a detailed wiring process 120. Before the partial areas are wired, the terminal couple which do not use the top layer on the existent wiring path to sufficient length for the machining are found by referring to a wiring path storage device and the path which uses the top layer preferentially when the terminal couple are wired. Namely, the top layer is not used for inter-terminal wiring that uses the top layer where machining is easy on the existent wiring path as much as possible, and the top layer is used preferentially for inter-terminal wiring which does not use the top layer yet.

Title: Image pre-processor
Inventor: OGAWA SHIGETAKA
IPC: H04N1/40
Filed: 1992-08-19
Abstract: PURPOSE:To correct the dynamic ranges different by the originals into a fixed dynamic range through the image pre-processing. CONSTITUTION:A photoelectric conversion device 1 converts the optical image information put on the optical signals included in an original into the analog image information put on the analog electric signals. An A/D converter 2 converts the analog image information outputted from the device 1 into the uncorrected digital image information put on the digital multilevel signals. An original foundation detecting part 4 detects the foundation density level of an original based on the uncorrected digital image information. A black level detecting part 5 detects the black levels of characters included in the original based on the uncorrected digital image information. A gamma correcting part 3 is controlled by both parts 4 and 5 and applies both ABC and gammacorrections at one time to the uncorrected digital image information given from the converter 2. Therefore an easy-to-control digital control method is applied to a dynamic range instead of the conventional analog method.
