Filed: 1982-10-15
Abstract: PURPOSE:To realize a balancer, which is simple in construction and the space necessary for which is small, by a method wherein rocking members are added to a hot gas engine equipped with a counterweight in order to cancel the horizontal inertial force additionally developed by said counterweight. CONSTITUTION:A first rocking member 711 is fixed upward from a displacer piston arm 41 in such a manner that the center of a first balance weight 71 lies on the line S, which is parallel to the center line L of a cylinder and at the same time passes through the fulcrum shaft center P of a displacer piston side arm 4 when the crankpin 21 of a displacer piston side holds the position of a point M or N. A second rocking member 721 is fixed downward from a power piston arm 42 in a similar manner. Because the horizontal inertia forces Fay and Fby developed by the first and second balance weights 71 and 72 respectively are in the same direction when the horizontal inertia force Fcy of the counterweight 17 becomes maximum, the inertia force Fcy is effectively cancelled.

Title: Camera
Inventor: IZUKAWA KAZUHIRO
IPC: G11B5/02
Filed: 1994-07-12
Abstract: PURPOSE:To realize a recording circuit whose circuit constitution is simple and whose production is easy by alternately performing energizing and reflux to a magnetic head for recording. CONSTITUTION:The recording circuit is constituted of input signal terminals 31 and 32, NOT circuits 33 and 34, an AND circuit 35, OR circuits 36 and 37, resistances 38 to 41, PNP transistors 42 and 43, NPN transistors 44 and 45, diodes 46 and 47, a power source 48 and the magnetic head H. It is desirable to apply a nearly fixed current to the magnetic head H for magnetic recording characteristic but the difference is not generated in a magnetically recorded state on film even when a current value changes to a certain extent in saturation magnetic recording. Then, the time for energizing the magnetic head H is set on a condition that the recording current changes. Therefore, by repeating the energizing and short circuit for a comparatively long time, the magnetic head R is energized within the change of the current, so that nearly the fixed current is applied to the magnetic head H without using a high accurate circuit like a constant-current circuit.

The resistor layer is etched to form a heat generating resistance film 9a leaving it between the electrode conductors 81... and 82... and then, a protective layer 10 is formed. As the partially protruding layer is built in this way, the heat radiating property is improved as compared to that when said layer is composed of a material with a low heat conductivity and thus, the adhesivity of the recording medium to a heat generating section can be improved with ease by setting the height of the protruded layer sufficiently high.
