Title: Plate fin heat exchanger and its manufacture
Inventor: NAKAMURA YOICHIRO
IPC: F28D9/02
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To facilitate the formation of a wavy fin part while maintaining the heat transfer performance equivalent to that of the fin. SOLUTION: The fin members 12, 13 formed by obliquely setting the fluid flowing direction Y of a flat plate fin 11 are alternately disposed on a plate 14 to constitute the fins 20 of the respective layers so that a fluid channel 15 become zigzag. Thus, in the case of manufacturing the fin 20, the manufacture is facilitated as flat plate fin 11. When assembling as the fins 20 of the respective layers, the heat transfer performance equivalent to that of the wavy fin is obtained by so setting as to become alternately oblique fluid channels 15. The manufacture of the fin 20 is facilitated to increase the thickness of the fin material to increase the durability and improve the brazing properties and the fins 20 can be densified by improving the moldability of the fin.

Title: Filter circuit
Inventor: KOJIMA KOJI
IPC: H03H15/00
Filed: 1990-11-09
Abstract: PURPOSE:To reduce circuit size by constituting a circuit capable of optionally attaining plural delay values in the case of removing ghost from a television signal of a single shift register and plural selector circuits each of which selects one terminal from plural terminals for outputting a signal of an optional delay value from the shift register and connects the selected terminal to a transversal filter to be the succeeding stage. CONSTITUTION:The shift register 1 time-sequentially arranges video signals. Each selector circuit 2 extracts a signal of an optional delay value from the register 1 and connects the extracted signal to its corresponding transversal filter 3. The number of selector circuits 2 and the number of transversal filters 3 are respectively equal to the number of waves for generating a multi-ghost. In this case, plural coefficients are stored in a coefficient memory 6 and the multiplication of plural coefficients is executed in the same data. In order to attain the multiplication of four times, four coefficients are stored in the memory 6 and these four coefficients are multiplied at four times the sampling frequency of data. In this constitution, three accumulation registers 8 less than the number (4) of times of multiplication only by one unit are prepared to temporarily store the results of sum of product operation. Each multiplexer 9 selects the input of an adder 7 from either one of the preceding adder 7 or the accumulation register 8.

Title: Handwritten character input device
Inventor: SEGAWA KIYOSHI
IPC: G06F3/0488
Filed: 1988-11-30
Abstract: PURPOSE:To simply input a handwritten character, without using a coordinate input board, and also, in a sense of writing a character on paper with a usual writing tool by providing a pen means containing two acceleration sensors. CONSTITUTION:An electronic pen 10 contains an (x) acceleration sensor 11, a (y) acceleration sensor 12 and a pen switch 13. A state of a movement of a pen point of the electronic pen 10 is always detected as (x) direction acceleration and (y) direction acceleration by the acceleration sensors 11, 12, and supplied to a device body 20 through a cable 30. A handwriting tracking processing part 23 derives successively a position of the electronic pen 10, based on a result of this detection and tracks writing of the pen point. In such a way, a handwritten input of a character, etc. can be executed simply in a sense of writing a character on paper with a usual writing tool, and also, since a coordinate input board such as a tablet, etc. is not required, the constitution can be simplified.

Title: Pressure fixing toner and its manufacture
Inventor: TAKEZAWA SATOSHI
IPC: G03G9/08
Filed: 1990-11-08
Abstract: PURPOSE:To obtain capsule toner where polybutadienes are fixed onto the surface of core material by covering the core material containing pressure fixing components with shell material composed of polybutadienes. CONSTITUTION:When moderately elastic shell material such as polybutadiens is used under comparatively low pressure to which toner in a developing machine is subjected, toner will never be destroyed because of elasticity of polybutadiens even if the shell of capsule toner is deformed. Thus, as the shell of capsule toner, polybutadienes are used, and as a fixing component, for example, amido compounds are used. This thereby prevents the occurrence of blocking and caking, and also prevents toner from being filmed onto the developing machine, carriers and sensitive drum, thereby proving fixing toner high in properties.
