Title: Cooling unit for heating body
Inventor: YAMAGUCHI HIROO
IPC: F28F3/06
Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To increase the area of contact between a support easing and fins by forming a level portion which is in parallel with a radiating plate at such a portion of the support casing to be jointed with the fins. SOLUTION: Two level portions 141 are formed on a support easing 140, at such portions of the casing 140 as to come in contact with the projecting portions (tips) of fins 130, in such a manner that the portions 141 extend substantially in parallel with a plate 110 and in a direction (i.e., the direction in which the corrugate fins extend) substantially orthogonal to the longitudinal direction of each ridge portion (i.e., a portion connecting the apexes of the tips) of the fins 130. According to this arrangement, since the casing 140 and the fins 130 are soldered together, in contact with each other at the portions 141 formed on the casing 140, the area of contact between the casing 140 and the fins 130 is increased.  Therefore, while reducing the number of manufacturing steps of a cooling apparatus 100 by means of integral soldering, sufficient joint strength can be secured between the casing 140 and the fins 130.

Title: Photo detector
Inventor: NOMOTO KAZUMASA
IPC: H01L31/10
Filed: 1994-08-05
Abstract: PURPOSE:To speed up photo detection by amplifying the output of a photodiode, using a single electronic transistor constituted of a photodiode and a minute tunnel junction. CONSTITUTION:In a photodetector, capacitor Cg is charged by the voltage across a load resistor RL when light hits a photodiode PD and a light reception current flows, and gate voltage Vg is applied to the gate of a single electronic transistor SET through this capacitor Cg. And, the change DELTAVg of the gate voltage Vg is measured by measuring the change DELTAQ=CgDELTAVg of the charge accumulated in this capacitor Cg. Accordingly, for a single electronic transistor SET, a minute change DELTAVg of the gate voltage Vg can be measured, so the value of the load resistor RL can be lessened, therefore the sensitivity elevation and the speed up of the photodetector can be materialized.

Title: Printer
Inventor: NARITA IZUMI
IPC: B41J29/26
Filed: 1985-09-18
Abstract: PURPOSE:To enable undesirable shifts in printing to be corrected and enhance operability, by simultaneously printing a plurality of preselected correction patterns when correcting undesirable shifts in printing. CONSTITUTION:With a power source turned ON, an initial value is set, and it is detected whether or not a switch 5 is short-circuited. When the switch 5 is short-circuited, a number of times of printing for correction is set. Where the setting is carried out by short-circuiting switches 5B and 5C, i=3. Next, j=O is set on a counter for the first correction pattern, a pulse to be supplied to a motor 2 is generated through a timer 6 based on a signal from a home position sensor 7, an acceleration/deceleration table for a carriage 3 is selected, and a stepping motor 2 is operated, thereby printing. Then, an operation j=j+1 is carried out, j and i are compared with each other, and printing is conducted while changing the acceleration/deceleration table until the condition of j=3 is reached, upon which a main controlling operation is restarted. On the other hand, when short-circuiting of the switch 5 is not detected, an initial operating switch is confirmed, and the next main controlling operation is carried out. By this, undesirable shifts in printing can be corrected efficiently and appropriately.

Abstract: PURPOSE:To eliminate the necessity for the supply of thinning solution and periodical exchange of ink and air extraction by arranging a recovery pipe from a gutter, a supply pipe to a jet nozzle and an air extraction pipe so that they are all interconnected to an ink bottle. CONSTITUTION:Aqueous ink in a bottle 1 is interconnected to an air trap 3 through an ink supply pipe 15 and it is spouted from a nozzle 8 through a pump 5, a filter 6 and an electromagnetic valve 7. Ink not used for printing is recovered by a gutter 8 and returns to the bottle 1 through a pump 10 and a recovery tube 12, and air separated in the bottle is discharged into the atmosphere through an air extraction pipe 16. Since the density of ink rises as moisture is evaporated during circulation, the bottle is replaced by the warning of a liquid level switch 25. This arrangement eliminates the necessity for a density sensor, supply of thinning solution, periodical exchange of ink in the system and air extraction, therefore the maintenance of the ink supply device is facilitated.

Title: Gas generator missile firing system
Inventor: ZUNGU BUI FUAN
IPC: F41A1/08
Filed: 1990-08-01
Abstract: PURPOSE: To make a missile launchable front a container without receiving any relatively strong reaction force, by launching the missile front the front end of the container by pressuring a piston to drive the missile by means of a propellant gas generator, and, at the same time, by giving a reverse inertia force to the missile by ejecting the gas from the gas generator backward from the aft end of the container through a nozzle. CONSTITUTION: A missile 12 is brought into contact with a piston 20. When a propellant fuel 34 is ignited, a high-pressure gas 38 moves a piston 20 by sliding the piston 20 on the inner end of the missile 12 and launches the missile 12 from the front end of a container by driving the missile 12. Since the piston 20 is substantially sealed to the internal wall of the container, most or all of the high-pressure gas 38 does not pass through the piston 20 and all forward forces are utilized to move the piston 20 and missile 12. Part of the gas generated from a gas generator which drives the piston 20 moves backward through the hole of the container and is ejected from the aft end 16 of the container, generating a counterforce which is given to the missile 12. The counterforce substantially eliminates the reaction force in a missile launch system.
