IPC: F24C1/00
Filed: 1989-04-04
Abstract: PURPOSE:To improve heat exchanger effectiveness between a heater and an airflow by setting the difference in level of the ceiling of a heater case closer to the side of a fan rather than right over the upper part of a heater and allowing the difference thereof to incline toward the heater in the form of a taper. CONSTITUTION:The height A of a space up to a ceiling of a heater case 5 on the upper part of a heater 3 is made lower than the height B of another space on the upper part of a fan 4 and the difference in level of the ceiling of the heater case 5 is set closer to the side of a fan 4 rather than right over the upper part of the heater 3 and allowed to incline toward the heater in the form of a taper 7. An airflow is allowed to linearly flow in the space between the ceiling of the heater case 5 and a partition 2, and bend in the direction of the heater 3 in accordance with the shape of the taper 7 of the ceiling of the heater case 5 in this side of the heater 3. An airflow speed is heightened by this squeeze and the air flow of a higher speed from the fan 4 is allowed to blow on the whole surface of the heater 3. The air flow receives new thermal energy from the heater 3 to which electricity is supplied to generate heat to be a hot air of higher temperature to allow the air flow to flow in a heating chamber 1 from an opening part 6 of a peripheral part of the partition 2 so as to heat foods in the heating chamber 1.

Title: Operation of serial type recording apparatus
Inventor: KATAYANAGI JUN
IPC: B41J19/18
Filed: 1986-04-14
Abstract: PURPOSE:To make it possible to prevent the jamming of a sheet at the feed time of the sheet even before the leading end of the sheet is taken by a discharge roller, in feeding the sheet, by moving a carriage to the center at every line feed until the leading end of the sheet reaches the predetermined position between a recording head and the discharge roller. CONSTITUTION:Until the leading end of a sheet 5 reaches the predetermined position between a recording head 4 and a discharge roller 11, for example, reaches the position immediately before the discharge roller 11, a carriage 3 is controlled so as to be moved to almost the center of the sheet 5 in the lateral direction thereof at every line feed. During a time when the leading end of the sheet 5 does not reach the discharge roller 11 and is held to a freely movable state, the carriage 3 is moved to almost the center position of the sheet in the lateral direction thereof each time when line feed is performed by recording operation and, thereafter, the feed of the sheet is performed. Therefore, the warpage of the sheet 5 at the feed time of the sheet can be suppressed to the min degree and, as a result, the jamming of the sheet generated by the hooking of the sheet with the guide roller provided to the discharge side of the recording head 4 of a sheet feed roller 1 can be prevented.

Abstract: PURPOSE:To certainly erase a character by appropriately utilizing a back delete system and a non-back delete system by erasing a printed character and the printed character stored in the first memory means corresponding to the first erasure indication means and again erasing the erased character corresponding to the second erasure indication means. CONSTITUTION:When an erasure key 11 is pushed down, it is investigated whether the content of a line buffer 23 is an NUL code and the processing of a back space 10 is executed. By this method, a character 's' can be erased from the surface of paper. When the character 's' is not completely erased, the erasure key 11 is pushed down while a code key 12 is pushed. ln this case, the content of an erasure buffer 24 is 'S' and the character 's' is allowed to impact against a paper surface 35 through an erasure ribbon 34 and stripping- off operation can be again executed. By this processing, stripping-off effect is further enhanced.

Title: Recording method of synchronizing signal
Inventor: KATOU MISAO
IPC: G11B20/14
Filed: 1982-05-20
Abstract: PURPOSE:To assure the detection of synchronism, by showing a bit series that never emerges in the code series after conversion although the data is converted by means of the modulation algorism of a 4-8 modulating system and applying said bit series to a synchronizing signal. CONSTITUTION:The time axis compression is applied to an original data train which is fed from a data input terminal 12, and then 16 bits of a pseudo synchronising signal are inserted with every 16 words of the original data through a pseudo synchronizing signal adding circuit 13. Furthermore 16 bits of CRCC are inserted before 16 bits of the pseudo synchronizing signal through a CRCC adding circuit 14. The 4-8 modulation is performed by a 4-8 modulating circuit 15 for original data train, and the part where the pseudo synchronizing signal is modulated is replaced with a normal synchronizing signal by a synchronizing signal addition circuit 16. Thus a frame underwent a conversion consists of 32 bits of synchronizing signal, 16 words of data containing 32 bits, and 32 bits of CRCC respectively. This frame is then delivered through an output terminal 18 after NRZI modulation carried out by an NRZI modulating circuit 72.

Title: Method for stabilizing ground surface
Inventor: ISHIKAWA TAKANAO
IPC: E02D17/20
Filed: 1990-03-31
Abstract: PURPOSE:To improve the water absorbing property, water holding property and plants growing property of soil dressing, by mixing the soil dressing with synthetic resin emulsions, fly ash and calcium hydroxide, for application to the ground surface and adding pH buffer agents to the mixed soil dressing. CONSTITUTION:Synthetic resin emulsions, such as polyvinegar vinyl, styrene- butadiene copolymer and polychloroprene, are mixed in the range of 1-10weight% of soil dressing. For a consolidation agent, fly ash and calcium hydroxide are mixed in the range of 2.5-6.0weight% of the soil dressing. Then pH buffer agents, such as aluminum sulfate and superphosphate calcium, are mixed by 2-6 weight per 100 weight of the consolidation agent. This bonds the soil dressing particles more strongly and prevents rain water from sweeping away the soil dressing. In addition, this consolidates basement materials in a short time. This also improves the germination rate of seeds and the growth of plants.
