Title: Composite word processing system of for "kana"/"kanji" conversion
Inventor: FURUTA SHIGEKI
IPC: G06F17/22
Filed: 1984-05-14
Abstract: PURPOSE:To attain the simple and rapid conversion of a composite word in ''kana'' (Japanese syllabary)/''kanji'' (Chinese character) conversion by forming a longest coincidence detecting part, a partial conversion part, a conversion deciding part, a composite word registering area, etc. and converting a part to be converted as it is to display the converted part. CONSTITUTION:At the execution of ''kana''/''kanji'' conversion, the longest coincidence detecting part 9 in a ''kana''/''kanji'' conversion part 8 detects the longest coincidence part out of ''kanji'' information loaded to a dictionary memory 6-1 or the like as to a word to be converted which is stored in an input character buffer 3. The detected part is set up in a converted result buffer 13 through a partial conversion part 10. When receiving the information that the converted result is correct, the conversion deciding part 11 decides the conversion and informs the contents of the buffer 13 to a document editing part 14. If the converted and decided result includes plural words, a composite word registering part 12 registers the result in composite word registering areas 7-1, 7-2 as a composite word. Consequently, the converted result can be selected from the areas 7-1, 7-2 similarly to one word at the conversion of the composite word and the simple and rapid conversion of a composite word can be attained.

Title: Gas burner for hot air heater
Inventor: HARA SHIYOUICHI
IPC: F23D23/00
Filed: 1984-05-14
Abstract: PURPOSE:To decrease the size of a structure, by a method wherein an upper burner turned up and a lower burner turned down are connected with each other through the medium of a partition in a manner that primary heating-to-redness and throats are positioned in reverse direction to each other. CONSTITUTION:Burner bodies 13A and 13B are connected through a partition 16 in a manner that primary heating-to-redness meshes 14A and 14B and throats 15A and 15B are positioned in a reverse direction to each other, and a combustion part is formed with an upper burner 2A turned up and a lower burner 2B turned down. The upper burner 2A and the lower burner 2B are vertically combined together in a manner that the tapered-off forward ends thereof are positioned in a reverse direction to each other, and this reduces an occupied area as compared with a device which is disposed in a plane manner, and enables a decrease in the size of a hot air generator 6. The upper burner 2A and the lower burner 2B are connected with each other through the partition 16, and thereby, if either the 2A or the 2B is in an OFF-state, the partition 16 is heated. Thus, if either the 2A or the 2B is in an ON-state, if the burner, being in an OFF-state, is brought to an ON-state, a rise speed is increased, and a generation rate of an offensive odor and carbon monoxide is reduced.

Abstract: PURPOSE: To secure fitting strength and preferable appearance by forming a projecting surface to a cavity surface side on one die, and holding a mirror of size to be projected from the projecting surface to secure the clearance where the thermoplastic resin is slipped into the space between the die and the edge of the mirror. CONSTITUTION: A projecting surface 12 from a general surface 13 of a cavity is formed on one forming die 11. A mirror 20 of such size as to be slightly projected from the projecting surface is temporarily held by the projecting surface 12 in a die-opening condition. In the initial stage, forming dies 10, 11 are in the opened condition, and the thermoplastic resin 30 is pressed into the clearance to allow sagging. When the thermoplastic resin 30 is arranged between the dies, the air is blown, and a nozzle 40 is introduced into the thermoplastic resin from the lower part at the edge position of the forming dies, and the air is blown to form a hollow part in the resin. After the resin forming is completed, the dies are opened, and the end trimming is achieved to obtain a hollow sun visor 50 where the mirror is embedded.

Filed: 1983-05-31
Abstract: PURPOSE:To soften an impact force and to prevent damage of a spool etc. by providing a speed changing device to a motor that drives the plunger of a case attaching and detaching mechanism, and slowing down operation speed at the time of detaching and attaching the case. CONSTITUTION:The plunger 14 of a cartridge case attaching and detaching mechanism is moved vertically by a specified DC motor. When attaching or detaching the case, the operation speed of the DC motor is slowed down by a speed changing device. When loading, the plunger 14 is lowered, and a medium part 3 is pushed out by an idler key 16. The plunger 14 is further lowered and a tab 18 of a spool 1 is engaged with a clutch 20 of a spool motor 19 and mounting is effected. The process is reversed when unloading. As the speed of attaching and detaching is slowed down, the impact force is softened, and the damage of the spool 1 etc. can be prevented.

Title: Information processor, commodity registering device and program storage medium
Inventor: MIICHI KUNIHIRO
IPC: G06F1/30
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To provide an information processor where a small and inexpensive back-up power source is used, a time required till main power is recovered to an application operation possible state when it is recovered from power interruption is shortened and the reduction of a working rate is suppressed. SOLUTION: When the power interruption of main power is detected by a power interruption detecting parat 9, the information processor 1 starts power supply by the back-up power source 8 so as to execute operation back-up. When a passage time from the detection of power interruption by a timer 11 is measured and power interruption is continued for more than a prescribed time, power supply to a peripheral device 5 is stopped and a shut-down processing is started. Therefore, capacitance required for the back-up power source 8 is made to be the small one so that the small and the inexpensive back-up power source is used. When the power interruption of main power is restored till a prescribed timing, the shut-down processing is not started so that the working rate of the information processor 1 is not reduced.
