Title: Developing ink for lithographic plate
Inventor: KUNICHIKA KENJI
IPC: C09D11/02
Filed: 1987-02-27
Abstract: PURPOSE:To obtain the title ink which gives a visible image faithfully reproducing an image region, does not cause fill-in, is easy to handle, has excellent stability even after the lapse of time, and provides excellent operating efficiency, by using a polybasic acid monoester derivative of a polysaccharide as an emulsion-stabilizing protective colloid for an aqueous phase. CONSTITUTION:A polysaccharide comprising preferably glutinous starch or fractionated amylopectin is reacted with a polybasic acid such as succinic acid to give a polybasic acid monoester derivative of a polysaccharide (e.g., succinic acid monoesterified starch), having at least one free carboxyl group, if necessary in the form of an alkali metal salt or NH4 salt, having a degree of substitution of 0.001-0.5 and a viscosity of 500cP or lower (in 20wt.% aqueous solution, at 20 deg.C). An oil phase consisting of 0.001-10wt.% coloring agent, such as carbon black, 0.3-30wt.% volatile solvent immiscible with eater, etc. is emulsified and dispersed in an aqueous phase of a pH of 2-4, consisting of 0.1-30wt.% above-mentioned derivative and, if required, 0.1-50wt.% (based on the derivative) water-soluble salt of a polyvalent metal, 20wt.% or less water-soluble resin, etc. through the use of 0.1-5wt.% surface active agent.

Title: Mos transistor
Inventor: FUJII EIJI
IPC: H01L29/78
Filed: 1988-02-26
Abstract: PURPOSE:To suppress a leakage current in a simple way, by making the impurity concentration in the region of a semiconductor layer located between the first and second gates to be lower than that of a drain region. CONSTITUTION:The first drain located between two gates 16 and 17 is formed in such a way that it has a concentration which is lower than that of the second drain. Then, a potential blocking layer is formed between the first drain 13 and a place which is directly below the gates 16 and 17. As a result, positive holes which are generated by a high electric field between the gate 17 and the second drain 14 are not accumulated in the whole transistor region but are recombined around the potential blocking layer and they are extinguished. Thus, the increase of a leakage current in a gate reverse direction voltage is suppressed.

IPC: H01S5/028
Filed: 1989-02-27
Abstract: PURPOSE:To prevent the loss of reflected light rays caused by scattering by a method wherein semiconductor possessed of a crystal face orientation different from that of a semiconductor substrate is grown on the side face of a groove which is not shifted from a mask using a organic metal thermal decomposition method, and a film serving as a reflective face is formed on the surface of the semiconductor. CONSTITUTION:A semiconductor board 1 is selectively etched using a mask 2 of a dielectric film formed on the semiconductor substrate 1 to form a groove provided with a side face with no step between the dielectric film and the semiconductor substrate 1, and the groove is filled with a semiconductor layer using an organic metal thermal decomposition method, where the growth of the semiconductor layer on the side face of the groove takes place in a lateral direction besides the growth on the base of the groove at a speed lower than that on the base of the groove. At this point, the semiconductor grown on the side face of the groove overhangs outside of the dielectric film of the mask 2 and a (100) face appears. The growth of the semiconductor layer starts centering on the appeared crystal plane, and the semiconductor protruding like a horn can be grown. By this setup, a planar projection reflective mirror extremely high in reflectivity can be obtained, where the loss of reflected light rays due to scattering hardly happens.

Title: Spool valve
Inventor: TANAKA KYOJI
IPC: F16K11/07
Filed: 1990-02-27
Abstract: PURPOSE:To reduce the volume of oil leakage from a high pressure port to a low pressure port by forming an intermediate land which changes over from a condition in which it fits into a valve bore into a condition in which enters into an intermediate annular groove, in association with the change-over operation of a spool, in an annular middle section of the annular groove of the spool fitted in a valve bore, the annular middle section allowing a high pressure port and a low pressure port to be communicated with each other. CONSTITUTION:At a neutral position of a spool 8, the pressure of an input port P is lowest but the pressures of output ports A, B are intermediate. Accordingly, when the input port servers as a high pressure port, the output ports servers as low pressure ports. However, when the output port serves a high pressure port, an output port T serves as a low pressure port. Further, since an intermediate land 13 and a main land 29 of the spool 3 block the communication between the high pressure port and the low pressure port, hydraulic oil from the high pressure port leaks into an intermediate annular groove 21 by way of a gap defined between a valve bore 12 and the intermediate land 13 or the main land 29, and then leaks from the intermediate annular groove 21 into the low pressure port by way of a gap defined between the valve bore 12 and the main land 29 or the intermediate land 13 in a step-like manner.
