Filed: 1982-12-27
Abstract: PURPOSE:To improve runnability, wear resistance and corrosion resistance by providing a vapor phase polymn. layer contg. boron, carbon and hydrogen on a ferromagnetic layer to be directly disposed on a base. CONSTITUTION:A vapor phase polymn. layer contg. boron, carbon and hydrogen is provided on a ferromagnetic layer to be disposed directly on a base. A compd. of boron, carbon and hydrogen is used to improve poor lubricity by making use of high hardness, corrosion resistance and high adhesion to the ferromagnetic layer which are the outstanding characteristics of the material contg. boron. The film thickness of the vapor phase polymn. layer of the boron comp. is preferably in a 20-1,000Angstrom  range, and is more particularly preferably in a 200-600Angstrom  range. If the thickness is <20Angstrom , the film is too thin and there is no effect of an overcoating. If the thickness exceeds 1,000Angstrom , the space loss between the recording medium and a magnetic head is increased and a reproduced output is decreased.

Abstract: PURPOSE:To prevent, wires for recording electrodes from loosening and coming from grooves when and after the wires are wound around a winding jig. CONSTITUTION:Wires 11 for recording electrodes are allowed to be wound around a winding jig 1, while fixing them, at portions among wire retaining grooves 3 and pins 7L, 7R and, even in the case where the wires 11 for the recording electrodes tend to penetrate through the grooves 3 from a direction in which the wires are greatly inclined against the wire retaining grooves 3, it is so designed that the wires for the recording electrodes are wound around the winding jig after the wires 11 guided up to the corresponding wire retaining grooves 3 are fixed among the grooves 3 and the pins 7L, 7R so as to be in the same state that the penetration angle theta is made zero. By this method, the wires 11 for the recording electrodes penetrate into the wire retaining grooves 3 without coming off from the grooves and, even thereafter, the wires do not have any deviation of their positions. Thus, the recording electrodes arrayed at a fixed pitch in a straight line are formed.

Filed: 1988-09-14
Abstract: PURPOSE:To control a lower margin accurately by a method wherein after a paper feeding a sheet feed amount is stored in a memory, a sheet size is discriminated according to the amount stored in the memory at the detection of the trailing end of the sheet by a sheet end sensor, a remaining printing area is obtained from the sheet length and the feed amount, and a printing is carried out by the remaining amount. CONSTITUTION:When a sheet end sensor 18 detects the trailing end of a sheet 7 during printing, the size of the currently printed sheet 7 is obtained from the length of an area which has been already printed. A remaining printing area is calculated by subtracting the length of the already printed area from the length dimension of the sheet 7. In this manner, the possibility that the length of a total printing area may change according to the accuracy of the sheet end sensor is eliminated; thus, a correct and stable printing area can be determined.

Abstract: PROBLEM TO BE SOLVED: To reduce a radio transmission loss, to reduce transmission line installation cost and to realize secure and stable communication/call by setting sewerage to be a ratio transmission line, installing prescribed reflectors at the right angles branch points of the sewerage, thereby constituting the transmission line. SOLUTION: A reflector A: 8 reflecting in one direction and a reflector B: 9 reflecting in two direction are properly arranged in the branch points of a sewer 13. In the reflectors A: 8 and B: 9, vertical and lateral sizes are set to be the length of one wavelength of a transmission radio frequency. They are miniaturized and reflection is made efficient. They are disposed to an upper part in the sewer so that the sewage flow is not obstructed.

Thus, a radio transmission line loss can be reduced even in the sewerage having a right-angled part. The element of the intra-sewerage antenna 10 is constituted of an orthogonal polarized wave. Thus, fading is reduced and stable and secure data communication is realized.
