Patent JP-H02122177-A (JP)
Title: Refrigerator
Inventor: YAMAMOTO OSAMU
IPC: F25C1/18
Filed: 1988-10-31
Abstract: PURPOSE:To surely produce transparent ice by a method wherein forced pre- cooling is immediately halted when ice making is started during forced pre- cooling operation, and water is rapidly cooled continuously only by a cooling plate during cooling period in which water reaches 0 deg.C. CONSTITUTION:When an ice making switch 20 is turned on by a user during defrosting operation, 'H' signal is input to a timer 43, and 'H' signal is output from 'd' output for a time period t'1, causing a transistor 30 to be turned ON and a relay contact 23 to be closed, so that a compressor 21 and a fan 6 are brought into continuous operation. During this period, the water in an ice making tray 15 is rapidly cooled without heating by a heating plate 12, and reaches 0 deg.C in a short time period. Next, when time period t'1 has elapsed, 'H' output is output from 'e' output of a timer 37 for a time period t'0 during which a transistor 36 is turned ON and a relay contact 24 is closed, so that a heater 11 is turned ON. Thereby, the heating plate 12 above the surface of water in the ice making tray 15 is heated so as not to freeze the surface first but to gradually cool and freeze the water from a cooling plate 13 on the bottom towards the surface. Then, transparent ice is made after a time period t'2 since output is changed to 'e' output.

IPC: G06F13/18
Filed: 1991-09-27
Abstract: PURPOSE:To shorten the waiting time of another bus master due to a bus back- off request. CONSTITUTION:When reading a shared memory 40 by another bus master 50, a write buffer control circuit 64 compares an address on a shared bus 30 with the addresses of tag registers 621-62n by comparators 661-66n and when coincidence is detected at any one of the comparators 661-66n, the bus back-off is requested to the other bus master 50. Subsequently, the addresses are successively selected to the address detecting the coincidence by a selector 65, and write access is executed to the shared memory 40. Then, the bus back- off request to the other bus master 50 is canceled, the other bus master 50 executes read access and after the access is completed, the write access in a standby state in FIFO memories 61 and 63 and the tag registers 621-62n is executed to the shared memory 40.

Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To decide a fuel flow rate according to a parameter for optimization so as to increase catalyst efficiency by correcting a fuel flow rate for the fuel intake of an internal combustion engine. SOLUTION: A closed loop air-fuel control system 116 in a PI controller 100 achieves an air-fuel ratio gradually changed from a stoichiometric air-fuel ratio to a lean side in response to rich exhaust gas component instruction by steadily reducing a fuel supplying speed. With respect to lean instruction by a heated exhaust gas oxygen sensor(HEGO) 113, a 'jumping return' command is immediately given to a fuel injector 122 to obtain mixed gas having a stoichiometric air-fuel ratio. Then, the closed loop air-fuel control system 116 steadily increases the fuel supplying speed to obtain an air-fuel ratio gradually changed from the stoichiometric air-fuel ratio to a rich side. Then, after the passage of holding time, the fuel supplying speed is suddenly reduced, and mixed gas having a stoichiometric air-fuel ratio is generated.

Abstract: PURPOSE:To surely form a stable excellent image even at the time of a halftone, by setting conditions similar to the operating conditions of an image forming means immediately after the leading edge section of an original to the leading edge section of the original. CONSTITUTION:The quantity of reflecting light from the surface of an original is detected by means of an optical sensor 1 and, when the frequency of the power supply is 50Hz, the first developing bias value V1 is calculated with a microcomputer 7 at 8-point sampling. Then, the next sampling division is also started in parallel from the 5th point in the course of the first sampling division and the next bias value V2 is calculated at the 8th point. The successive bias values V3, V4... are also calculated in the same manner thereafter. The bias value V2 immediately after the leading edge section of a picture is used as the first developing bias value V1. Therefore, no toner fogging, etc., are produced and excellent images can be formed even if the leading edge section of the picture is in a halftone.

Title: Solid-state image sensing element
Inventor: ABE HIROSHI
IPC: H04N5/369
Filed: 1988-10-31
Abstract: PURPOSE:To prevent a smearing phenomenon by forming each region correspond ing to the photodiode of an opposite conductivity type well which is deeper than the region corresponding to one conductivity type buried region so that it may become deeper from the surface of a semiconductor substrate. CONSTITUTION:P<-> type wells 9 below photodiode junction 3 are formed in an N-type silicon substrate 1 in such a way that they are deeper than P-type wells 10 of N-type buried regions 4. Further, the impurity concentration of P<-> type wells 9 is lower than that of the P-type wells 10. This is reason why only the P<-> type wells 9 are depleted and electrons (a) and (b) are not absorbed by the N-type buried regions 4, when photoelectric conversion carriers overflow ing from N-type regions 3N of the photodiodes are absorbed into an N-type silicon substrate 1. As some components diffusing crosswise in the direction of the N-type buried regions are absorbed out of the photoelectric conversion carriers which are generated below the photodiodes into the N-type silicon substrate, smearing phenomena are thus exceedingly decreased.
