Title: Electronic cash register
Inventor: EGUCHI TATSUO
IPC: G07G1/12
Filed: 1982-04-01
Abstract: PURPOSE:To check registered data efficiently by allowing receipt numbers of necessary registered to succeed one after another at all times. CONSTITUTION:In addition to a main memory area wherein receipt numbers for normal registering operation, an RAM41 has an auxiliary memory area wherein receipt numbers for reregistration are set. In reregistration mode, when a department key for registration is pressed, the set department is displayed on a display 12 and printed on a receipt by a printer 14. Departmental totalization, however, is not carried out. When a deposit/cash key is pressed, the total amount of money is displayed on the display 12 and then printed on the receipt. The update of the sales totalization, however, is not performed. Further, a receipt number obtained by adding (1) to a receipt number for reregistration in the auxiliary memory is printed on the receipt. Therefore, the contents of the main memory area are never printed on the receipt during the reregistrating operation.

Abstract: PURPOSE:To improve the follow-up properties of photosensitive film and prevent void from being left in lamination by a method wherein the photosensitive film, which is reduced by forming photosensitive layer on flexible backing film, and substrate, which is produced by forming conductor pattern on insulating substrate, are laminated under heat and reduced pressure to each other under the condition that the photosensitive layer directly contacts with the surface, on which the conductor pattern is formed, and, after that, heated further. CONSTITUTION:Photosensitive film is laminated onto substrate by the publicly known laminating method and, firther, left under the atmospheric pressure and temperature of 50 deg.C or higher. The heating temperature is 50C or higher preferably about 60-100 deg.C. The satisfactory heating time is 1-15min, preferably about 3-10min.

Title: Magnetic recorder and reproducer
Inventor: MURAYAMA YUUKI
IPC: G11B11/10
Filed: 1981-04-14
Abstract: PURPOSE:To reproduce the high density recording with a high S/N ratio, by using the magnetooptic effect of a main magnetic pole consisting of a magnetic thin film having an easily magnetizable axis on the film surface of a vertical magnetization recorder/reproducer and a high permeability magnetic thin film split into two. CONSTITUTION:A main magnetic pole consists of two split high permeability thin films 21 and 22 and a magnetic thin film 24 having an easily magnetizable axis vertical to a vertical magnetization film surface 11, and an auxiliary magnetic pole 15 is located opposingly to it. The optical beam from a laser light source 25 is collected on the magnetic thin film 24 with a lens 27 via a polarizer 26. The magnetic thin film 21 is magnetized according to the magnetization direction of the vertical magnetization film 11. As a result, the polarized plane of the optical beam incident to the film 24 is rotated. The reflection beam becomes an intensity difference signal through the lens 27, a half mirror 28 and a photodetector 29 and the magnetizing information is reproduced at a photodetector 30. Since the resolution of reproduction is determined not by the spot size of light, but by the thickness of the main magnetic pole, the high density recording can be reproduced with the high S/N ratio.

Title: Circulation speed control device for grain dryer
Inventor: FUJIOKA SADAKAZU
IPC: F26B17/14
Filed: 1988-03-11
Abstract: PURPOSE:To control an increase in the temperature of grain so as to prevent the grain from deteriorating, by increasing the circulation speed in a grain dryer in order to reduce detention time of the grain in a drying chamber when the moisture content is high or a large amount of high moisture grain is contained. CONSTITUTION:A specified amount of grain is fed into a storage bin 1, and a specified moisture content, at which drying operation is to stop, is set by an operating input setter 31. When a burner 10 is ignited to start the drying operation, a moisture content detector 20 is simultaneously put into operation to measure the moisture content of each grain specified times, and an average value of the measurements is calculated for each time. In case the average moisture content does not reach the specified moisture content, scatter in the measured moisture content of grains is calculated, and the circulation speed of the grain in the dryer is set according to the amount of scatter and the average moisture content calculated. The higher the average moisture content of the grain and the larger the amount of scatter, the higher the circulation speed is set. Therefore, in case of high moisture content of the grain, a rotary valve 14 rotates at a high speed to allow the grain to pass through a drying chamber 14 in a short period of time, so that an increase in the temperature of the grain is controlled, preventing the grain from deteriorating.

Title: Shrink film excellent in color tone
Inventor: FUKUDA YUJIRO
IPC: B29K67/00
Filed: 1987-03-11
Abstract: PURPOSE:To obtain a shrink film, which is excellent in color tone, shrinkage characteristics, strength and weatherability and is also favorable in productivity, by using a material wherein the major component of the film is polyester obtained by polymerizing specified terephthalic acid, isophthalic acid and ethylene glycol as major starting raw materials through esterification and the shrinkage factor of the films is the specified value or higher. CONSTITUTION:The major component of a film concerned is polyester, which is obtained by polymerizing terephthalic acid and isophthalic acid, satisfying a terephthalic acid-to-isophthalic acid ratio = 50/50-95/5 (by mol), and ethylene glycol as major starting raw materials through esterification. At the same time, the shrinkage factor of the film at 100 deg.C in an air oven for 5min is 40% or more in either longitudinal direction or lateral direction. If the compositional ratio of terephthalic acid to isophthalic acid is below 50/50, the strength of the obtained film lowers remarkably. Further, if the ratio exceeds 95/5, the shrinkage factor of the obtained film becomes small. If the shrinkage factor is below 40%, the film does not come into tightly contact with a package or a product after shrinkage and is not preferable.
