Abstract: PURPOSE:To improve the vertical resolution by using a contour emphasis signal having a peak at the upper limit of its vertical spatial frequency so as to emphasize the contour of a video signal. CONSTITUTION:The title circuit consists of an image pickup element 1, preamplifiers 2-5, adder circuits 8-10, a field switch 11, 1H delay circuits 12, 13, contour emphasis circuits 14, 15, a luminance signal generating section 16, a color matrix circuit 17, a color signal generating section 18, a process encoder 19, an output terminal 20, a pulse generating circuit 21, and a synchronizing signal generating circuit 22. Then the image pickup element 1 of the 2-line simultaneous readout system is used and video signals read from three lines of its picture element matrix arranged at an equal interval are used to form a contour emphasis signal. Thus, the vertical spatial frequency characteristic of the contour emphasis signal is extended up to the effective line number of the picture element matrix and reaches its upper limit. Thus, the vertical resolution is enhanced up to the limit of the vertical spatial frequency.

Title: Ink ribbon cassette
Inventor: HIRANO HIROFUMI
IPC: B41J31/05
Filed: 1984-07-11
Abstract: PURPOSE:To obtain an ink ribbon cassette, which can print data in a manner that a color mixing is reduced, by coating the back of a specific color band with a sheet through which ink does not permeate. CONSTITUTION:A color ink ribbon 1 is housed in a ribbon cassette proper 2. A sheet 3 through which ink does not permeate is fitted to the section of a color easy to be particularly affected by the compound color as compared to other colors such as yellow in a color band 1a. The compound-color preventive sheet 3 has the same width as the color band 1a, and is stretched between both arms 2a. When yellow is printed, the yellow band 1a is struck against a platen 5 through the sheet 3. Printing fades to some extent at that time, but no trouble is generated on actual use. Even when yellow and other colors are superposed one upon another, yellow fades, but a superposed character is distinct between other colors are clear. Color bands except yellow may be coated with the color mixing preventive sheet.

Title: Preparation of compound semiconductor luminous element
Inventor: YASUDA MICHIROU
IPC: H01L21/306
Filed: 1978-11-24
Abstract: PURPOSE: To enable to etch both simultaneously by treating a p + -type layer with a low speed etching liquid while an n-type compound semiconductor crystal fracture layer with a high speed etching liquid.  
     CONSTITUTION: The ratio of etching speed of a p + -type layer and an n-type GaP crystal becomes smaller with increased concentration of hydrochrolific acid or nitric acid and with lowered liquid temperature. Under a certain condition this is reversed and the etching speed of an n-type GaP crystal fracture layer becomes greater than  that of the p + -type layer. Through said etching condition no measure for protecting  the p-type layer is required thus enabling to etch simultaneously the p + -type layer as well as n-type GaP crystal.

Abstract: PURPOSE:To improve both the reliability of an electrode part and the yield of nondefective products, by forming a metallic film of >=4 layers composed of 3 different types of metallic materials on a piezoelectric substrate and carrying out alternately the etching process for shaping of the film thickness and the decreasing process of the electrode film. CONSTITUTION:A comb-shaped electrode Al film 21, an etching stopping Ni film 22, a resist pattern preserving Cr film 23 and an inductance Al film 24 are consecutively vapor-deposited on a piezoelectric substrate 1. Then a photoresist pattern 25 is formed on the substrate 1. Then the pattern 25 is exfoliated to form a resist pattern 25' only at the inductance part. Then the film 24 is removed by etching, and furthermore the films 22 and 21 are removed by chemical etching to obtain a state shown in the figure (c). Finally the films 22 and 23 are removed by etching to obtain a surface acoustic wave device filter having a desired electrode as shown in the figure (d). In such way, all metallic films can  be vapor-deposited through the same process. This can increase the intensity of close adhesion of the electrode as well as the reliability for a surface acoustic wave device.

Title: Control method for air conditioner
Inventor: UCHIUMI TAKASHI
IPC: F25B1/00
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To obtain a superheat control method for air conditioner in which the refrigeration cycle 15 stabilized by bringing the (S-H) amount quickly close to a target (S-H) amount. SOLUTION: In a superheat control for matching the temperature difference ((S-H) amount) between the suction temperature of a compressor 1 and the heat-exchanging temperature of an evaporator with a target (S-H) amount, an outdoor unit control section 11 detects the delivery temperature based on a detection signal from a delivery temperature thermistor 12 when the (S-H) amount is smaller by a specified amount or more than the target (S-H) amount and actuates a timer section 11a. The delivery temperature is detected again upon time up at the timer section 11a and a delivery temperature variation calculating section 11b calculates the delivery temperature variation from delivery temperatures detected previously and currently.  If the (S-H) amount is kept smaller by a specified amount or more than the target (S-H) amount until time up, a pulse variation varying section 11c varies single variation of the opening/closing of an electronic expansion vale 5 to a larger value, i.e., increases single variation of the opening/closing of the electronic expansion vale 5.

In the process, the vibration applied to the plunger 3 is transmitted to all resin 12 to be transferred. Accordingly, the gate 14 of the cavity 15 in which the resin is early charged completely is continuously finely fed by the vibration without stay, and not cured.
