Patent JP-S5934657-A (JP)
Title: Semiconductor device
Inventor: NAKAI MASAAKI
IPC: H01L29/78
Filed: 1982-08-20
Abstract: PURPOSE:To enable to decrease the malfunction by a method wherein a surface layer is made the same conductive type as the semiconductor layer immediately thereunder, and the concentration of the surface layer is more increased than the impurity concentration of the semiconductor layer. CONSTITUTION:In one picture element in the photo diode array part of a solid- state image sensor, a P type Si substrate 71 has the impurity concentration of approx. 5X10<14>cm<-3>, and a P type well layer 72 has a higher concentration than the substrate 71, the impurity concentration of approx. 6X10<15>cm<-3>. The potential of the well 72 can be led out directly from the back surface via the substrate 71 of the same conductive type, therefore the resistance R in the transverse direction of the well 72 is eliminated accordingly CR time constant determined by the R and the capacitance C between the well and the substrate becomes the minimum, and the variation of well potentials can be decreased and made uniform. Consequently, horizontal shading due to the variation of well potentials is eliminated, and thus the dummy signal due to vertical smear can be suppressed. Also in the case of applying the semiconductor device to an N- MOS memory, the charge diffusion due to alpha rays is suppressed by a potential barrier, therefore the malfunction remarkably decreases.

Patent JP-H0438031-A (JP)
Title: Local area network
Inventor: SASHITA YOSHIO
IPC: H04L12/40
Filed: 1990-06-04
Abstract: PURPOSE:To make the size of the system small without revision of a node address of each local area network when plural number of same node addresses exist by setting a network address area to a destination address part of a transmission frame with a node group and storing an address pointing out a local area network of a destination. CONSTITUTION:A transmission frame 47 sent from a node 61a of a transmission line 1 of a 1st LAN is stored in a RAM 39 by an MPU 7. The MPU 7 collates an M address of a destination address part 49 with a network address stored in a 1st LAN address area 29 and a 2nd LAN address area 31 of a RAM 27. When the address M is zero, a transmission frame 47 is aborted. When the address M is equal to a network address of the 2nd LAN address area 31, the address M of the destination address part 49 is set to zero and the address is sent to the 2nd LAN transmission line 3. Thus, even when the same node address exists in the other LAN, the relevant node address is not required to be revised.

Title: Gas combustor
Inventor: SHIRAI SHIGERU
IPC: F16K31/06
Filed: 1979-11-07
Abstract: PURPOSE: To provide an arrangement for the gas combustor equipped with a gas- pressure controller in use of a diaphragm, which is capable of preventing occurrence of gas poisoning trouble or gas explosion due to unburnt gas leaked into the atmosphere in case that the diaphragm is damaged due to long use or by other reasons.  
     CONSTITUTION: The diaphragm 18 is fixed to the uppr end of a valve body 15 which is adapted for opening and closing a valve opening 14 of a gas-pressure controller 11, in the manner that it separates a gas passage 19 and a back-pressure chamber 20 from each other. This back-pressure chamber 20 is communicated to a gas combustion chamber 35 via a connecting pipe 34, but it is formed with no other port or clearance communicated to the atmosphere than that communicated to the connecting pipe 34. Such a gas-pressure controller can control the gas pressure by lifting or lowering the valve body 15 by the aid of a plunger 24 and the diaphragm 18 through control of the current supplied to an electromagnetic coil 25. With such an arrangement, if gas is leaked into back-pressure chamber 20 due to damage of diaphragm 18, the leaked gas is carried via pipe 34 to combustion chamber 35 and burnt therein. Therefore, it is enabled to prevent occurrence of a serious accident due to the leakage of gas.

Title: Conversion processing system for compression data
Inventor: KUROGAKI YUKIO
IPC: H04N1/419
Filed: 1986-06-20
Abstract: PURPOSE:To secure the correct actuation of an expanding device without recognizing the device of the remote side by defining apparently the received compression data as the data having the prescribed width. CONSTITUTION:A compressing/expanding device 5 compresses the input image data down to the prescribed width for transmission under the control of a processor 1 or expands the received compression data. A compression data converting device 6 adds a fixed insertion code equal to 9 dots and a length control code equal to 6 bits to the compression data of 33 dots, for example, if received from the device of the remote side. Thus the device 5 can apparently decide reception of the compression data of prescribed 48 dots. As a result, an expanding device of the reception side can apparently decide that the compression data of the prescribed width is received.

Title: Method and apparatus for manufacture of planographic offset printing plate by silver salt diffuse transfer method
Inventor: BATOROMU BUERURANDEN
IPC: G03F7/30
Filed: 1995-05-19
Abstract: PURPOSE: To make it possible to well wash a planographic offset printing plate by a DTR (silver salt diffusion transfer inversion) by applying a curtain of an aq. medium in a specific form to the printing plate and washing the plate. CONSTITUTION: An exposed material 9 is developed with an aq. alkaline processing soln. in the presence of a developing agent and a silver halide solvent to obtain silver images on a base. The silver halide emulsion layers and the arbitrary layers on the silver images are washed and removed by the aq. medium to expose the silver images. At this time, the curtain 21 of the aq. medium is applied to the surface of the material on the silver halide emulsion layer side to cross the width of the material and is substantially crossed across the processing direction 11. The curtain is applied in the form of the counter current to the processing direction 11, by which the washing is executed. In such a case, the nozzle on a spraying head is so designed that the small drops of the soln. collide against the surface of the material 9 at all points to ensure the uniform coating of the surface.  The pressure of the spraying curtain 21 is so regulated as to ensure that the small drops of the spraying collide against the material 9 with sufficient impact to wash the material.
