Title: Still camera
Inventor: NISHITANI YASUHIRO
IPC: G03B19/02
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a still camera capable of continuing a photographing action even when a liquid crystal display monitor cannot be driven because a power source battery is consumed and which is strong in catching a shutter chance. SOLUTION: A finder optical axis by a finder optical system 38 is split in two by a half mirror 33. An image forming surface on one finder optical axis is provided with an area type image sensor 39. The other finder optical axis is guided to an eyepiece 43 by a reflection mirror 37 so that the image forming surface can be enlarged and viewed. Thus, since an object image can be observed not only on the liquid crystal display monitor 12 but through a finder eyepiece window, the photographing action can be continuously executed even when an image pickup part 20, specially, the monitor 12, whose power consumption is large, cannot be driven because the terminal voltage of the power source battery is lowered.

IPC: H01L41/09
Filed: 1980-04-02
Abstract: PURPOSE:To prevent a mechanical system including a video head from resonating by applying a signal from a driving signal generator between electrodes of a transducer via a current limiting resistor and by specifying the relation of the resistance value. CONSTITUTION:The output signal of driving signal generator 20 is applied between electrodes of piezoelectric element 1, provided with video rotary magnetic head 2 of an auto tracking device, via current limiting resistance 6.

Title: Closed melting furnace
Inventor: SHIINA KENTARO
IPC: H05B11/00
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To suppress the amount of generating slug and dust by arranging a coil for induction heating on the lower side wall of a furnace body. SOLUTION: A closed melting furnace comprises a furnace body 1, a furnace cover 2 to cover in an airtight state the furnace body 1, and an electrode 3A extending through the furnace cover 2 to the interior of a furnace, and a water- cooled coil 4 for induction heating is arranged at the lower side wall of the furnace body. Scrap is charged in the furnace body 1 and after the furnace cover 2 is closed, the electrode 3A and the coil 4 for induction heating are charged with a power, and arc heating and induction heating are simultaneously performed. Induction heat is effected from the outside, situated closer to the side wall, of a charged raw material. Meanwhile, since high arc heating is effected in the vicinity of a center, charged scrap is heated on a whole, and melting is rapidly progressed. Since, during melting, the furnace is closed, entrance of outside air is suppressed to a minimum, and the generation of slag and dust due to oxidation of a raw material is suppressed to a minimum.
