Title: Film unit with lens
Inventor: SAKATA HIROSHI
IPC: G03B17/02
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a film unit with a lens where the aperture part of a slit formed on the outer periphery of an operation part is narrowed in order to prevent a foreign matter from infiltrating from the slit. SOLUTION: A shutter button 9 is elastically integrally provided on a front cover 16 in a state where it is separated by the slit 45 while leaving a part of its outer periphery. A spacer 47 formed to surround the outer peripheral wall of the shutter button 9 along the inner peripheral wall of the slit 45 is inserted in the slit 45 from the outside of the cover 16. Since the spacer 47 abuts on the upper surface of a winding dial inside the cover 16, the winding dial is slidably held at the upper part of a cartridge chamber. The outer peripheral surface of the spacer 47 is pressed to the inner peripheral surface of the slit 45 by the elasticity of the spacer 47, and projections 47a integrally formed at respective parts on the outer peripheral wall of the spacer 47 are engaged with the inner peripheral surface of the slit 45 so as to prevent the spacer 47 from coming off.

Title: Continuous casting method of dissimilar kind molten steel
Inventor: KOSHIKAWA TAKAO
IPC: B22D11/10
Filed: 1978-06-20
Abstract: PURPOSE: To block mixing of dissimilar kind molten steels to a mininum and surely connect dissimilar kind billets by immersing and burying the cooling material having pouring voids into unfrozen molten steel and pouring molten steel of other kind before the surface of the molten steel freezes.  
     CONSTITUTION: Immediate after molten steel A is poured and cast through an immersion nozzle 1, a cooling material 3 having multiple voids is immersed and buried in the unfrozen molten steel. Before the molten steel A does not freeze at the upper liquid level of the molten steel A, molten steel B of dissimilar kind is additionally poured and continuous casting is resumed. Thereby, solid phase is produced in the molten steel A around the cooling material 3 and mixing with the molten steel B is blocked. In addition, the flow of the molten steel B is converted to parallel dispersion flow by the voids of the cooling material 3 and therefore mixing between the molten steels A and B is well blocked. This method obviates the production of any cracks at the connection parts of the dissimilar kind molten steels and lets the continous casting of the dissimilar kind molten steels to be accomplished safely and rapidly.

Title: Power converter for generator utilizing variable magnetic field
Inventor: WATANABE ASAKI
IPC: H02M7/48
Filed: 1993-03-09
Abstract: PURPOSE:To allow stabilized supply of output voltage regardless of fluctuation in the induced voltage of generator by employing the amplitude value of induced voltage as a feedfoward control element for a converter control means. CONSTITUTION:A PWM converter control means 5 receives outputs from a generator output voltage detecting means 6, a generator output current detecting means 7, means 8 for estimating an induced voltage based on the outputs from the means 6, 7, and a converter output voltage detecting means 9. The control means 5 controls the input voltage to a PWM converter 4 such that the power factor becomes 1, i.e., the induced voltage of generator matches in phase with the output current of generator. When the induced voltage of generator is detected and added, as a feed forward compensation element, to the effective component command of PWM converter voltage, influence of induced voltage does not appear in active and reactive output currents from the generator. Since the output is not susceptible to fluctuation of induced voltage, it can be used as high quality power supply.

Title: Data processor
Inventor: ISHIKAWA AKIHIKO
IPC: G06F11/00
Filed: 1987-03-28
Abstract: PURPOSE:To directly detect whether a built-in clock stops or not by comparing two counted values held in a specified interval with a starting signal from the outside. CONSTITUTION:When the starting signal appears in an input terminal IN connected to an operation table, a host device and a processor for supervision, etc., a first register 32 directly holds the counted value of a counter 31 which counts the clocks from the built-in clock oscillator 20. A second register 33 holds the counted value of the counter 31 in a specified interval set in a delay unit 34 after the starting signal appears in the input terminal IN. When the holding of the counted value in the register 33 is completed, a comparator 35 compares the counted values of both registers 32 and 33 and it outputs a normal signal when they do not coincide. And when they coincide it decides that the oscillator 20 does not output the clocks and outputs an abnormal signal to an output terminal OUT.

Abstract: PURPOSE:To eliminate unnecessary vibration and noise from a movable unit by increasing or decreasing the drive current of other drive coil which does not switch the drive state corresponding to the switching direction when the drive state of one drive coil is switched. CONSTITUTION:When an input pulse is supplied to a signal input terminal 8, a control circuit 7 conducts transistors 9a, 10a, and flows a drive current through a coil 13a.
