Title: Magnetic head
Inventor: KAGAWA HIROBUMI
IPC: G11B5/23
Filed: 1989-12-07
Abstract: PURPOSE:To make reading and writing impossible by a conventional magnetic head and to completely prevent illegal actions by curving or bending and forming a gap provided in a core. CONSTITUTION:In a core 1, a gap 2 is formed while being bent in the shape of a circular arc. When data are written into a magnetic recording medium by this magnetic head, the data are parallelly recorded in the shape of a circular arc-shaped band to a data track corresponding to the shape of the gap 2. Therefore, when the circular arc-shaped data written by this magnetic head are read by a magnetic head having a linear gap, the data and the gap are not made correspondent and accordingly, the data are read as different contents and can not be exactly reproduced. Thus, the data can not be exactly read by the normal magnetic head having the linear gap and reversely, the data written by the normal magnetic head can not be read by this magnetic head.

Title: Detector for amount of refrigerant packed in freezing cycle
Inventor: MATSUOKA FUMIO
IPC: F25B45/00
Filed: 1989-12-07
Abstract: PURPOSE:To display distinctly the actual amount of a refrigerant packed by specifying the total amount of the refrigerant packed at a point of time when the suction pressure of a low-pressure shell type compressor becomes a substantially maximum value as an optimum value, disposing an operation means for calculating the rate of the refrigerant packed in a freezing cycle on the basis of the optimum value thus specified, and also disposing a display means for displaying the calculated rate of the refrigerant packed. CONSTITUTION:A predetermined amount of a refrigerant is packed from a refrigerant packing port 12, and a suction pressure Ps at a point of that time is detected by a pressure sensor 10. Subsequently, a microcomputer 11 judges whether the increased rate of the suction pressure Ps with respect to a predetermined DELTAM of the refrigerant increased is not more than a preset value S, and, in the case where the judgement result indicates No owing to a shortage of the refrigerant in a freezing cycle, DELTAMkg of the refrigerant is packed again. By this method, when the amount of the refrigerant packed is increased, so that the suction pressure Ps reaches a substantially maximum value, the total amount SIGMAM of the refrigerant packed at a point of that time is specified as the optimum amount of the refrigerant to be stored in a storage means. The rate C of the refrigerant packed is then computed by applying the formula of C=(SIGMAM+kDELTAM)/SIGMAM on the basis of the total amount SIGMAM of the refrigerant packed and the amount kDELTAM of the refrigerant additionally packed thereafter, and the rate C thus computed is numerically displayed on a display unit 13.

Title: Funnel type gun type oil burner
Inventor: OHARA SEIJI
IPC: F23D11/24
Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To manufacture an inexpensive low NOx oil burner requiring no heat resistance by providing a combustion air nozzle and stabilizing ignition and flame using a funnel being cooled with the combustion air. SOLUTION: Oil is injected from an oil nozzle 1 into the space 3 in a funnel 2 provided with an air nozzle 4 and an air passage 5 at a position separated from the oil nozzle 1. Combustion air cools the funnel when it passes through the air passage 5 and then it is injected from the air nozzle 4 at an angle suitable for an injection 6. Consequently, the injection 6 is reatomized and evaporated partially with radiation from the flame before being combusted in the funnel. It is the principle of low NOx jet mixing type burner. An extremely low NOx burner can thereby be realized. Since the combustion air passes through the air passage 5 on the outside of the funnel before entering into the air nozzle 4 and cools the funnel, an expensive heat resistant material is not required.
