IPC: H04N1/06
Filed: 1984-03-22
Abstract: PURPOSE:To decrease the number of picture memories by recording one or plural pictures on a sheet so as to apply split recording to the recording sheet by means of the main scanning performed by the optical beam scanning system and of the sub-scanning where the recording sheet is moved relatively to the optical system. CONSTITUTION:When power is applied, a drum 13 is turned at a constant speed in a prescribed direction and the recording sheet 2 is supplied from a supply magazine via a supply device 3.

The position of the sheet 2 is detected (22) and the picture recording is started at the position where the sheet 2 is made stable by rollers 17, 18. Then the sub-scanning of the recording is performed by the movement of the sheet 2 attended with the turning of the drum 13. On the other hand, the main scanning is performed by an optical system 27 or a beam generator (not shown). Then the position of the sheet 2 is detected (25) and the sheet is wound on the drum 13 or goes out of the drum 13.

Title: Electric power unit having dummy resistor
Inventor: TAKAHASHI KAZUO
IPC: G05F1/56
Filed: 1979-05-01
Abstract: PURPOSE: To prevent not only a decline of power supply efficiency but also unnecessary heating, by decreasing a current flowing in a dummy resistor in case a load current is large, and increasing a current flowing in the dummy resistor in case the load current is small.  
     CONSTITUTION: In case a load current is large, voltage across a resistor 11 is increased and an output of an operation amplifier 7 is increased. In this case, since the terminal voltage of a resistor 13 is increased, the voltage difference between the input terminals of (+) and (-) of an operation amplifier 8 is decreased, an output of the amplifier 8 is decreased, and after all, a current flowing in a dummy resistor 3 is decreased. In case the load current has been decreased, the terminal voltage of the resistor 11 becomes small, an outut of the operation amplifier 7 is decreased, and the voltage across the resistor 13 is decreased. As a result of the foregoing, the voltage difference between the input terminals of (+) and (-) of the operation amplifier 8 is increased, and an output of the operation amplifier 8 is increased, as well. When the output of the operation amplifier 8 has been increased, a current flowing in the dummy resistor 3 is increased.

Title: Flashing device and camera provided therewith
Inventor: MORI NOBUYOSHI
IPC: G03B15/05
Filed: 1991-02-27
Abstract: PURPOSE:To obtain an excellent light distributing characteristic without making the device large and damaging the stream-line shape thereof by forming at least one surface of an optical panel so that the peak position of the relative intensity of irradiating light is deflected in a prescribed direction. CONSTITUTION:The flashing device is constituted of the optical panel 1 which is almost plane, a semi-cylindrical reflector 2 and a flash discharge tube 3 obtained by filling up a cylindrical glass tube with inactive gas. Then, not the front surface direction of the flashing device shown by the arrow of a continuous line but the direction shown by the arrow of a dotted line is irradiated. A condensing zonal groove Fresnel lens is formed on the side of a body to be irradiated of the panel 1 and a linear groove Fresnel lens obtained by arraying linear grooves from A to A' is formed on the tube 3 side. Then, the linear groove Fresnel lens is formed so that an angle made by the normal lines of respective refracted surfaces and the front surface direction of the flashing device becomes smaller according as it goes to A' from A. In such a case, such distribution that the whole normal lines of the refracted surface are biased to a left side is obtained. Thus, emitted light is deflected to the left side and condensed in left and right directions by gradually changing the angle of the refracting surface.

Title: Phenolic resin molding material
Inventor: KUMAGAI TAKU
IPC: C08L61/00
Filed: 1984-03-21
Abstract: PURPOSE:To provide the titled molding material which has good moldability, does not cause mold fogging during molding and gives moldings having good electrical and physical characteristics, by blending catechol with a resol type phenolic resin contg. woodmeal and an inorg. filler. CONSTITUTION:A phenolic resin molding material is obtd. by blending 20- 50pts.wt. woodmeal, 10-30pts.wt. inorg. filler such as clay, CaCO3 or talc and 2-14pts.wt. catechol with 100pts.wt. resol type phenolic resin alone or mixture thereof with a novolak type phenolic resin. Since a molding material contg. a resol type phenolic resin does not contain hexamine as a hardener, the ammonia content thereof is low and hence, corrosion or staining due to ammonia is hardly caused. However, the quantity of phenol in gas generated during molding is increased and hence, mold fogging is liable to be caused. By adding catechol, mold fogging can be prevented.

Abstract: PURPOSE:To make the influence of noise due to disturbance light hard to receive by clocking the pulse period of an optical signal outputted from a light receiving element and judging the optical signal of a light emitting element that is a light receiving object depending on whether or not a clock value is within a prescribed range. CONSTITUTION:The light receiving elements 8a-8d perform photoelectric conversion by receiving a light synchronous signal emitted from the light emitting elements 7a-7d first, and output a synchronous signal VSYC based on the light synchronous signal.

Title: Plumb bob equipment

IPC: G01C15/10
Filed: 1984-03-23
Abstract: PURPOSE:To perform operation even when a weight is slightly away from a gauge mark or even when the circumference is a little bit dark by inserting a light emission body and a power source into the weight, and emitting a light beam from the hole at the lower end of the weight and illuminating the gauge mark. CONSTITUTION:The weight 2 is reverse conic and a large-diameter hole 2d for storing the battery 6 and a small-diameter hole 2f for storing the light emission body 8 are formed at the center part; and a small-diameter (about 1mm.) hole 2g is further formed at its lower end while extending to the lower end surface of the weight 2. The upper end of yarn 1 is fitted to a body whose verticalness is to be detected, and when a lid 3 is clamped, a switch contact plate 4 is lowered to close an electric circuit, turning on the light emission body 8. Its light is emitted downward as a light beam from the small-diameter hole 2g. At this time, a tripod and the length of the yarn are only adjusted so that the beam strikes the gauge mark. Consequently, the weight need not be put as close to the gauge point as a conventional plumb, so damage to the tip need not be considered and the verticalness is detected by a single-time adjustment even if the circumference is a little bit dark.

Abstract: PURPOSE: To freely generate protruding letters in a pickup region set on the basis of full-stroke letters as reference by a method wherein protruding letters are reduced in size and incorporated on a letter panel, and the reduced letters are magnified by a factor of the reciprocal of the contraction ratio when they are picked up by a camera tube and regenerated on a display tube.  
     CONSTITUTION: Protruding letters are reduced to the size of bull-stroke letters and incorporated on a letter panel 5, and the data of reduction ratio are memorized in a memory unit 15.

CONSTITUTION:The first welding member 2 having high heat conductivity and a pair of the second welding members 3, 3 having low heat conductivity with the first welding member 2 sandwhiched therebetween are interposed between fayed faces of a pair of base metals 1, 1. When a beam L is irradiated on this part, the surface of the first welding member and a pair of the second welding members are melted by the heat of the beam L, and an alloy layer having higher light absorption rate than that of the base metal 1 is formed on this surface. The majority of the heat absorbed by the alloy layer is thermally insulated by the second welding members 3, 3 both sides of which are low in heat conductivity, and the heat is conducted in the direction of depth of the welding member 2 which is high in heat conductivity.
