Title: Rotary magnetic head
Inventor: ABE MITSUO
IPC: G11B5/53
Filed: 1991-10-16
Abstract: PURPOSE:To provide a rotary magnetic head device wherein its short-wavelength output can be enhanced without deteriorating its durability with reference to a magnetic head whose surface is smooth such as a metal vapor-deposited tape. CONSTITUTION:By setting the outer circumferential face 5 of cylinders 1, 2 which regulate the traveling operation of a magnetic tape 3 as a reference, a magnetic head 4 which is turned is arranged and installed in such a way that the height of its sliding contact face is nearly equal to the height of the traveling face 6 of the magnetic tape 3. The magnetic head is not thrusted and deformed when the tape comes into contact with the head; its contact force becomes nearly zero. As a result, even when the thickness and the surface roughness of a protective film on the surface of the magnetic tape are made very small, its durability does not become problematic. Thereby, the spacing loss of the title head device is reduced, and the recording density of the title head device can be enhanced.

Title: Light distribution controller in stroboscopic device
Inventor: KANEKO YOSHITARO
IPC: G03B15/02
Filed: 1987-10-22
Abstract: PURPOSE:To facilitate the light distribution for obtaining a photograph in which a light beam has spread over each part of an object to be photographed without using plural flash discharge tubes by forming a radiation light emission intensity distribution by the flash discharge tube so that the irradiation intensity center-of- gravity axis is positioned near the outside of a photographic screen. CONSTITUTION:A light distribution controller 300 is formed by a long square- like frame body 301 and a conversion plate 302 which is fixed to the front of this frame body 301. This conversion plate 302 is formed by plastic and its surface has a Fresnel lens surface. The Fresnel lens surface of this conversion plate 302 works so that a luminous flux P0 from a flash discharge tube, which is made incident on the conversion plate 302 is expanded, and also, goes to a luminous flux P1 in which the irradiation intensity center-of-gravity axis is positioned near the outside of a photographic screen, and the light emission intensity in that case shows a low intensity in a part of an area A of the photographic screen, and the irradiation intensity becomes strong toward the outside. In such a way, the operability in case of executing stroboscopic photographing of the photographic screen containing both a short distance object and a long distance object can be improved.

Abstract: PURPOSE: To prevent operation defect of a receiver due to line fault by outputting a monitoring-time presence voltage and a detection-time presence voltage by a detector, outputting the no-voltage-time line fault signal of a detection line by a receiver, and sending a dummy detection-time presence voltage to an outdoor machine and turning off a line fault signal circuit when the detection-time presence voltage is detected. CONSTITUTION: This device consists of a gas detector G, receiver R and outdoor machine S. The receiver R generates the monitoring-time presence voltage of 6V when the gas detector G is monitored, and when this 6V is sent out to the gas detector input terminal G+ of the receiver R through the gas detection line L, no current flows to the base of the transistor Q6 of a line fault signal circuit, so that the line fault signal is not sent to the line fault input side I1 of a receiver control circuit CPC. Further, when the gas detector G does not operate owing to a fault and a power failure of the gas detection line L, the monitoring-time presence voltage becomes no voltage of 0V and the line fault input is supplied to the line fault input side I1 of a CPU. The CPU processes the input to perform line fault alarm operation.
