Title: Circulator for high frequency and its manufacture
Inventor: MYOGA OSAMU
IPC: H01P1/387
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent cracking or chipping in a high frequency circulator due to external stresses in the manufacturing process of the circulator or the assembling process of an MIC(microwave integrated circuit). SOLUTION: A high frequency circulator is constituted by laminating a laminated circulator body 8 composed of a GND layer 4, a ferrite 2, an insulating layer 6-1, and an SIG circuit 3 upon an insulating substrate 1. Since the stresses applied by external forces are relieved by the substrate 1, cracking or chipping in the ferrite 2, etc., formed in a thin layer can be prevented, In addition, since holes 7 are arranged on the surface forming the SIG circuit 3 at the input-output spots of the circuit 3 for exposing the GND layer 4, the connection between the non-exposed GND layer 4 and an external MIC can be made easier.

Title: Control of thermal head
Inventor: KUBO TAKASHI
IPC: B41J2/355
Filed: 1988-04-18
Abstract: PURPOSE:To use a small capacity power supply as a thermal head by imparting a printing-permitting strobe of the thermal head from one shift register and controlling the data input to said shift register. CONSTITUTION:When a power supply VH rises, a RESET signal for setting the content of a printing data shifter 5 to 0 is inputted to prevent the generation of heat from a heat generating resistor 1. (N) printing data of one line are inputted to the DATA terminal of the printing data shifter 5 in synchronous relation to a carrier clock CLK and a latch pulse LATCH is emitted to a printing data latch 4 to latch printing data. Next, printing permitting data is inputted to a PDATAI terminal terminal 6 in synchronous relation to a carrier clock PCLK and, at the same time, a CYCE signal is set to 1(permission of printing) in order to be capable of reutilizing the printing permitting data. Herein, in order to hold stable recording density, the correction to the respective varying factors of an average heat generating resistance value, the temp. of a head substrate and a current supply time interval is performed by controlling three parameters of K(the number of heat generating resistors simultaneously permitted to print), tp(carrier clock cycle) and M(the number of times of a printing permitting cycle).

Title: Method for preventing corrosion of cooler for internal- combustion engine
Inventor: NAKAMUTA TANJI
IPC: F01P11/06
Filed: 1983-05-30
Abstract: PURPOSE:To prevent effectively the corrosion of a tightly sealed cooler using a circulating system by adding a hydrazine as an anticorrosive to fresh water for cooling in the cooler. CONSTITUTION:In a tightly sealed cooler using a circulating system for an internal-combustion engine, hydrazine which is a volatile substance causing no concentration and decomposition on the heat transfer surface is added to fresh water for cooling as an anticorrosive in place of conventional solid chemicals such as nitrite or polyphosphate. The amount of hydrazine added is >=200ppm. In case of 500ppm, the corrosion of the part contacting with the water can be prevented even when the engine is stopped for a lond period, and tightly sealed state is not maintained. Since 500ppm hydrazine shows the most significant effect, >500ppm hydrazine is not necessary.

Title: Photosensitive heat-developable image forming material
Inventor: YAMAZAKI KAZUKI
IPC: G03C1/498
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To ensure high contrast and low fog photographic characteristics and to improve image preservability by using silver salts of org. acids having a specified silver behenate content as a nonphotosensitive silver salt and incorporating a nucleating agent into a photosensitive layer contg. a photosensitive silver halide and/or its adjacent layer. SOLUTION: The photosensitive heat-developable image forming material has a photosensitive layer contg. a photosensitive silver halide, contains silver salts of org. acids having >=90 mol.% silver behenate content as a nonphotosensitive silver salt and contains a nucleating agent in the photosensitive layer and/or its adjacent layer. Since the silver salts of org. acids are used in combination with the nucleating agent, a high sensitivity and low fog contrasty image is obtd. In the case of <90 mol.% silver behenate content, fog increases, image preservability deteriorates and contrast is not sufficient. If the nucleating agent is not contained, a contrasty image suitable for a photomechanical process is not obtd.  Though the problems of the increase of fog and the deterioration of image preservability occur when the nucleating agent is added so as to obtain a contrasty image, the problems are solved by using the silver salts of org. acids having >=90 mol.% silver behenate content.

Title: Zoom lens having soft focus mechanism
Inventor: KAWAMURA ATSUSHI
IPC: G02B15/167
Filed: 1983-05-30
Abstract: PURPOSE:To easily obtain a soft focus effect with a zoom lens, by further moving a part of or the whole of lens group constituting the zoom lens from one end of the zoom area while the arrangement of the lens from one end of the zoom area while the arrangement of the lenses in the group is maintained. CONSTITUTION:The zoom lens of this invention is composed of five lens groups I -V and the figure shows a zoom lens having a focal distance range of 28.8- 97mm. and an F-number of F4 when f=52.85mm.. Each lens group moves along the loci shown in the figure. The Z and S of the figure represent the moving locus of the zoom area and soft focus area, respectively. As may be clearly understood from the figure, if soft photographing is started from one end of the zoom area when the one end is in an area (f=70-135mm., or so) which is suitable for portrait photographing, a soft cam can be formed on the extension line of a zoom cam and therefore, the constitution of the bodytube becomes simpler.

Abstract: PURPOSE:To obtain a printer which suppresses oscillation during rapid paper feed by providing a groove cam, for guiding a head pin, which consists of a head cam and a paper feed cam and enables a guide groove for the head pin to be selectively changed during printing and paper feed operations. CONSTITUTION:A contact part of a rapid paper feed lever 15 is caused to come in contact with a cam part 14-2, so that a paper feed cam 14 is located almost in close contact with a head cam 23. If the head cam 23 rotates in an arrow A direction, a head pin 22-1 is guided to a wall surface D and a shuttle head 22 moves in an arrow B direction. If a rapid paper lever 15 is rotated in an arrow F direction by the power of an electromagnet 18, the con tact part 15-1 comes off the rotating track of the cam 14-2, and the paper feed cam 14 is pushed in an arrow C direction by a paper feed cam spring 19. The paper feed cam 14 is slid on a bearing 17 in an arrow C direction. Therefore, a gap P is created between the paper feed cam 14 and the head cam 23. If the head cam 23 rotates in the arrow A direction, the head pin 22-1 is guided to the end E of the paper feed cam 14, and a shuttle head 22 moves in a thrust direction. These components control the movement of the shuttle head 22.
