Filed: 1980-04-26
Abstract: PURPOSE: To make possible the correct exposure controlling corresponding to the selected photographing modes by discriminating the photographing modes by program commands and performing the process controlling of the exposure operations and exposure controlling corresponding to the modes.  
     CONSTITUTION: The state of a selector gate ICS which selects the output corresponding to the photographing mode selected by an external switch EXSWT is discriminated by a sensing gate CS according to the program command read out from a ROM. As a result of this, the processing corresponding to the programs of the ROM is accomplished and the exposure operations corresponding to the selected photographing mode and the sequential controlling of the exposure system of the camera are accomplished. Hence, the optimum exposure corresponding to the selected photographing modes such as shutter-priority, aperture-priority, program and manual is controlled.

Title: Multi-point television conference system
Inventor: OKUZONO KEISUKE
IPC: H04N19/503
Filed: 1990-03-07
Abstract: PURPOSE:To allow the system to held a conference at multi-points without revision of a current television conference terminal equipment by discriminating for which terminal equipment a picture sent at present is with respect to a pattern revision request from a conference terminal equipment and outputting the pattern revision request to the terminal equipment only. CONSTITUTION:When an error takes place in a received picture of a conference terminal equipment D, a pattern revision request is sent from the conference terminal equipment D to a controller 1. Upon the receipt of the pattern revision request from the conference terminal equipment D, the controller 1 discriminates it that the picture received by the conference terminal equipment D is for a conference terminal equipment A and the pattern revision request by the in- frame difference code system is implemented to the conference terminal equipment A. Since the coding system of the conference terminal equipment A is changed from the inter-frame difference system into the in-frame difference system to send a picture of a talker, the conference terminal equipment D observes a normal and revised pattern via the controller 1.

IPC: H01L21/02
Filed: 1988-03-10
Abstract: PURPOSE:To make bubbles hard to remain in bonding surfaces and to reduce stress, by using a semiconductor layer in a fused state to bond two semiconductor substrates. CONSTITUTION:Two sheets of Si substrates 11 and 12 are prepared. The substrates 11 and 12 have SiO2/Si structures having SiO2 layers on the surfaces.

Filed: 1982-04-06
Abstract: PURPOSE:To minimize the size of an automatic valve which has a flowing water detective function by providing the valve with both a piston which gives a main valve a motive force for seating and a mechanism which detects flowing water. CONSTITUTION:When a pilot valve 15 is opened in response to actuation of a fire sensor or the like, a pressure in a pressure reducing chamber 30 is reduced so that a main valve 26, a piston 28 and an opening indicator 34 are pushed up by a pressure of a pressurized water at the primary side, namely, a valve is opened, thereby squeezing the pressurized water at the primary side to run to the secondary side. Some of the running pressurized water makes a pressure switch 11 turned ON. When the pressures in the primary chamber 24 and the secondary chamber 25 become approximately equal to each other, the main valve 26 falls and closed and a water supply hole 31 is closed. The pressure switch 11 is therefore turned OFF.
