Title: Photoelectric converter
Inventor: HOSHI JUNICHI
IPC: H04N5/369
Filed: 1998-08-05
Abstract: PROBLEM TO BE SOLVED: To realize a smart sensor suitable for reduction of pixels by making a light nearly identical to a light incident onto a photoelectric conversion element incident onto a semiconductor region that stores transferred signal charges and applying photoelectric conversion to the light in the semiconductor region so as to ensure a wide dynamic range. SOLUTION: A light nearly identical to a light incident onto a photoelectric conversion element is made incident onto a semiconductor region (FD) that stores transferred signal charges and the FD section applies photoelectric conversion to the light. An opening 16 is provided to a light shield film 18 on the FD section of this converter to make an incident light incident onto also the FD section. Since the FD section consists of a diffusion region 14 similarly to the case with a photodiode PD being a conventional photoelectric conversion element, in the case that a hole is made to the diffusion region 14 and a light is made incident onto it, electrons and holes in pairs being optical signal charges are generated. Thus, the FD section acts like a photoelectric conversion element equivalently.  A potential change due to the stored signal charges to the FD section can be monitored through a current flowing to a MOS amplifier.

Inventor: MIYA TAKAHARU
IPC: F25B1/00
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To provide an air conditioner in which refrigerant is prevented from staying in a compressor at a stop side and in its suction pipe during a heating operation of refrigerant or. SOLUTION: In the case that only a first compressor 21 is being operated when a refrigerant is heated, a shut-off valve 39 at an outdoor device ECU 35 is closed for every predetermined time and then a refrigerant circuit ranging from a refrigerant pipe 56 to the first compressor 21 is made to be a closed circuit. With such an arrangement as above, as gaseous refrigerant is discharged from the first compressor 21 to a refrigerant pipe 51, the refrigerant circuit which is a closed circuit is pumped down to cause a pressure within the circuit to be decreased and as this pressure is decreased, liquid refrigerant within a second compressor 23 or within a suction pipe 64 is rapidly gasified so as to eliminate a staying of the refrigerant. In addition, the outdoor device ECU 35 closes the shut-off valve 39 also when the second compressor 23 is energized again and its pump-down operation is carried out, thereafter the second compressor 23 is energized again.

Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To provide a medical image diagnosing device by which a stored list and an image are transmitted as against a request from another device. SOLUTION: An image communication block 38 receives the request of the list from an image observing device 40, reads the list from an image storage block 36 and transmits it to the image observing device 40. Besides, the image communication block 38 reads the requested image from the image storage block 36 when the required image is requested based on the list from the image observing device 40 and transmits it to the image observing device 40. In this case the transmission of the whole images in the image storage block 36 by a communication protocol is not realistic because it takes much time. Thus, a diagnosing X-ray device being the titled invention is provided with the image communication block 38 so that the request from the image observing device 40 can be directly responded and, therefore, an image keeping device is not required to be independently arranged.

IPC: G06T9/20
Filed: 1995-08-09
Abstract: PROBLEM TO BE SOLVED: To detect a boundary area with an optional shape in which pattern information is changed independently of the shape of a graphic constituting the pattern information. SOLUTION: A scanning means 1 scans the whole input picture by a mask having specific size and extracts the mask used for the scanning of the picture and an area separated by a fixed distance from the mask. A featured value calculating means 2 finds out a featured value by the use of the extracted area and temporarily stores the featured value in a featured value storing means 3. A boundary area judging means 4 compares the featured value with a reference value, and when a difference between both the values is more than a certain threshold, picture elements corresponding to the mask used for the picture scanning are judged as a boundary area. Processing described above is applied to the whole picture and a picture constituted only of a boundary is finally obtained.

Title: Gas introduction apparatus for cvd use
Inventor: TSUKUNE ATSUHIRO
IPC: H01L21/205
Filed: 1988-09-06
Abstract: PURPOSE:To enhance the uniformity of a reaction gas by a constitution wherein a plurality of groove parts which have been made so as to be in parallel with each other are provided or a plurality or groove parts installed on a grid are provided and a gas radiation sheet having a plurality of a gas discharge holes is provided in the groove parts. CONSTITUTION:A reaction gas introduced from a gas introduction hole 10 is diffused to a whole face of a gas radiation sheet 1 inside a gas diffusion chamber 2 partitioned by a gas diffuser 3; it is sent out to a reaction chamber 11 from small gas discharge holes 51 on the whole face of the gas radiation sheet 1. During this process, since a sheet thickness of groove parts 81 is thin, a stream of the reaction gas has no directivity; accordingly, the reaction gas passed through the gas discharge holes 51 is radiated easily and uniformly toward the reaction chamber from grooves 52 which have been made wide; a uniformly thick thin film is formed on a substrate for deposition use. During this process, the temperature of the substrate 5 to be deposited is raised by using a heater; heat from the heater is transmitted easily to the gas radiation sheet 1; the gas radiation sheet 1 is heated; mechanical strength of the material itself is weakened; however, the sheet is not deformed because a thick part of the sheet thickness exists. Thereby, the mechanical strength is enhanced; the uniformity of a film thickness of a deposit on the substrate for deposition use can be enhanced.
