Title: Recording material
Inventor: SATOMURA MASATO
IPC: B41M5/155
Filed: 1989-04-03
Abstract: PURPOSE:To enhance color forming properties and the stability of a developed color image, in a recording material utilizing such a phenomenon that a leuco dye forms a color upon the contact with an electron acceptive compound, by allowing an aliphatic alcohol compound to coexist in the same layer as the electron acceptive compound or in the layer adjacent to said layer. CONSTITUTION:Aliphatic alcohol means alcohol having about 8-60 carbon atoms in total and may have one or more kind of a substituent such as an alkoxy group, an aryl group, an aryloxy group or an alkylthio group and pref. has an m.p. of 150 deg.C or lower. This alcohol is also effective in a recording system not accompanied by heat-melting such as photosensitive pressure-sensitive paper or pressure-sensitive paper. Especially, the effect thereof is large in a system using a metal salt of a salicylic acid derivative as an electron acceptive compound. The aliphatic alcohol compound is used in an amount of 0.001-300 pts, pref., 0.05-2 pts. per 1 pts. of the salicylic acid derivative and adapted in an emulsified and dispersed state or in the co-dispersion state with the electron acceptive compound. A leuco dye-containing capsule is applied to the surface same or opposite to the electron acceptive compound layer to form a recording material.

Title: Visual inspection system for mounted substrate
Inventor: TAKEYASU KIYOO
IPC: G01B11/00
Filed: 1985-04-22
Abstract: PURPOSE:To improve an accuracy in detecting the shift of a position by providing a reference for detecting the shift of the mounting position of a part to be mounted to a surface from a substrate mounting design pattern itself. CONSTITUTION:A window 40 is set to a position which does not cover two portions in a substrate background. In this case, when the bounds of the window 40 is set so as to leave a given space relative to the two portion as shown in the accompanying drawing, the one window 40 does not include two background portions even when the positioning of the substrate involves some errors. When one and the other portions of the window 40 are set within a land 15 and the bounds of a substrate material 1, respectively, the threshold of conversion to binary notation required when the position of a chip part is recognized in the respective portions of the window may be changed in accordance with the brightness level of the background. Thus, by limiting the background in the window 40 to one kind, discrimination between the portion of this kind and the chip part can be facilitated.

Title: Magnetic head and its production
Inventor: KANEKO HIDEKI
IPC: G11B5/127
Filed: 1987-04-08
Abstract: PURPOSE:To prevent deterioration in characteristics by heat and to improve yield by using a silica sol as an adhesive agent for adhering constituting members of a magnetic head, more particularly, sticking of a substrate formed with a thin soft magnetic film pattern and protective plate. CONSTITUTION:The silica sol (colloidal soln. of high mol.wt. silicic acid anhydride) is used as the adhesive agent at the time of sticking the substrate 1 formed with the thin soft magnetic film pattern 3 and the protective plate 4. This silica sol serves as the good adhesive agent when subjected to a heating treatment, as the colloid particles adhere securely to the recesses of the joint surfaces and the particles create the secure bond by forming siloxane bonds with each other. The coefft. of thermal expansion is approximated to the coefft. of thermal expansion of the constituting members 3 of the magnetic head and the temp. for the heating treatment can be set below the temp. at which the characteristics of the thin soft magnetic film pattern are deteriorated. The deterioration in the magnetic characteristics of the thin soft magnetic film pattern is thereby obviated.

Title: Automatic scale
Inventor: HAJI SETSUO
IPC: G01G13/00
Filed: 1984-04-26
Abstract: PURPOSE:To make an automatic scale easy to handle by a method wherein the weight is determined with an arithmetic processor depending on the combination patterns of a plurality of weighing devices in the measuring mode and then, the number counted is obtained by automatically switching over to the counting mode. CONSTITUTION:Measurement is done with a plurality of weighing devices 1 in the measuring mode and signals of weights W1-Wn are inputted into a multiplexer 2. Then, the outputs are inputted into an arithmetic control section 4 to compute the combined weight values sequentially based on (2<n>-1) combination patterns. Among the weight values, those that stand between the upper and lower limit of the set weight are determined. Then, by switching over to the counting mode, the weight values thus obtained are divided by a single weight signal Wu and the results are converted to the number per one weighing device to compute combined counts based on the combination patterns preset. The number counted is compared with the set value to determine the optimal number. Thus, the automaic switching of the measuring mode over to the counting mode enables the accurate measurement with a simple operation.

Title: Semiconductor device and manufacture thereof
Inventor: IMAMURA KENICHI
IPC: H01L29/737
Filed: 1988-04-06
Abstract: PURPOSE:To minimize increase or variation of base resistance and to prevent variation of resonant voltage and decrease of current density, by interposing an InxAl1-xAs layer having composition whose forbidden band width is substantially equal to that of GaAs between emitter and GaAs collector layers. CONSTITUTION:A laminated structure in which at least a GaAs collector layer 3, a GaAs base layer 4 and an emitter layer 5 are stacked in that order is provided on a GaAs substrate 1. An InxAl1-xAs (0<x<1) layer 7 is interposed between the emitter and collector layers 4 and 5, the layer 7 having composition whose forbidden band width is approximately equal to that of GaAs. Since the InxAl1-xAs having the same band gap as that of GaAs and having a high selection ratio of etching is thus used, the band structure is equivalent to that in the case of absense of the etching stopping layer. Accordingly, element characteristics are not affected thereby.

Title: Power source device
Inventor: KOSHIN HIROAKI
IPC: H02M3/28
Filed: 1990-03-30
Abstract: PURPOSE:To interrupt a supply power for all the circuits in a device when abnormality occurs in a switching power source, by a construction wherein a thermistor is connected in parallel to a resistor for rush current suppression and a fuse melting with an overcurrent is inserted in series into a power supply line before it is branched. CONSTITUTION:When a section D-S is put in a state of short circuit, a high-frequency transformer Tr1 stops oscillation and generation of a voltage in a winding N3 discontinues. Consequently, a triac T1 is put in a state of noncontinuity and currents I2 and I3 flows through a resistor R1 and a thermistor TH respectively. Therefore, a rise in temperature is caused in the thermistor TH and a resistance value of itself decreases. Since this state proceeds in an accelerated manner and an input current is increased in a short time, a fuse F inserted into a power supply line before it is branched melts in a very short time. According to this constitution, a fault is checked with ease and, besides, a secondary fault of another circuit can be prevented.
