Title: Method for processing silver halide color photographic sensitive material
Inventor: FUJITA YOSHIHIRO
IPC: G03C7/26
Filed: 1986-07-29
Abstract: PURPOSE:To obtain stable development performance free from staining by processing a silver halide color photographic sensitive material provided with a silver halide emulsion layer on a reflective support with a color developing solution containing substantially no benzyl alcohol but a specified compound. CONSTITUTION:The silver halide color photographic sensitive material provided with the silver halide emulsion layer on the reflective support is processed with a color developing solution containing substantially no benzyl alcohol but at least one of the compounds represented by formula I in which Z is an atomic group necessary to form an aromatic ring, thus permitting stains occurring on short time development to be effectively restrained only by using the developing solution containing no benzyl alcohol but said compound of formula I.

Title: Manufacture of power ic device and clad material used in the same method
Inventor: OOTA TAKAYUKI
IPC: H01L23/12
Filed: 1986-07-29
Abstract: PURPOSE:To simplify a forming process and to enhance the reliability of a bonded part in a power IC device by preparing a clad material for a solder/Cu/ Ni-plating or solder/Cu/Sn-plating, thermally bonding the Ni or Sn-plated surface of the material to an alumina substrate, and then attaching a semiconductor element onto a soldered surface. CONSTITUTION:When a solder/Cu/Ni-plating clad material is, for example, used, a solder layer 2 is formed on one side surface of a Cu layer 6, and an Ni-plated layer 7 is formed on the other side surface of the layer 6. The layer 7 is thermally bonded to a ceramic substrate 5 through a solder 4, and the layer 7 eliminates the discoloring of the surface of the layer 6 by the heat at the time of bonding and a decrease in its solderability. After the Ni-plated surface of the clad material is bonded through the solder 4 to the alumina substrate, such as a ceramic substrate 5, and a semiconductor element, such as an Si chip 1 is mounted on the layer 2. Since it is worked integrally in this manner, the steps can be omitted, and the number of components can be reduced.

Title: Polling system
Inventor: SHIMADA FUMIO
IPC: H04L69/14
Filed: 1991-07-19
Abstract: PURPOSE:To reduce a series of polling time by reducing the transmission of number of commands. CONSTITUTION:The mode 1 is a mode for usual polling, and when a terminal equipment accepts a command POL(1) from a center equipment, the terminal equipment returns a response command ACK(1). In this case, if any data error is in existence, the center equipment sends again the command POL(1) for re-transmission processing caused by expiration of time. The mode 2 is an operation mode when the quality of a line is rather deteriorated, the terminal equipment sends consecutively the response command ACK(1) twice with respect to the command POL(1) from the center equipment. The center equipment validates the response command ACK(1) sent at first or the response command ACK(1) sent at a 2nd time which is received normally.

Filed: 1988-07-18
Abstract: PURPOSE:To use large parts of water in a long period without contaminating water quality by providing a vessel part for collecting dust below the water surface and cleaning dust on the bottom of the water while utilizing water pressure. CONSTITUTION:When the vessel part 1 of a dust collector is sunk below the water surface while holding the handle part 3 in a hand and the tip 2A of a dust collecting cylinder 2 is approached to dust on the bottom of the water, this dust is introduced into the vessel part 1 together with water in the periphery thereof by water pressure. Both dust on the bottom of the water and water are continuously introduced until the water surface in the vessel part 1 is regulated to the same height as the outer water surface. Thereafter when the whole dust collector is held up and carried to the outside of a water tank and inverted up and down, the introduced dust and water can be discarded through the hollow handle part 3. Furthermore when dust collecting work is stopped at the position wherein the water surface in the vessel part 1 is lower than the upper end part 2B of the dust collecting cylinder 2, such inconvenience that the dust collected in the vessel part 1 is allowed to flow back into the water tank can be avoided.

Title: Resist pattern formation
Inventor: YOSHIHARA KOICHI
IPC: G03F7/16
Filed: 1989-07-11
Abstract: PURPOSE:To improve resist sensitivity by specifying the temperature range at the time of prebaking in resist pattern formation wherein a substrate with negative electron beam resist applied is prebaked, exposed and developed. CONSTITUTION:Temperature for prebaking negative electron beam resist is made higher than temperature when heat bridge forming reaction occurs and also lower than 200 deg.C. By making the prebaking temperature higher than that with bridge forming reaction occurring, 140 deg.C for example, it is possible to improve sensitivity by substantially 15% or more. This improvement in sensitivity can lead reduction in lithography time. However, the prebaking temperature of 200 deg.C or higher is impractical since development failure due to heat fog occurs.
