Title: Comparator
Inventor: NISHIJIMA SHIROU
IPC: H03K5/08
Filed: 1983-02-02
Abstract: PURPOSE:To control automatically the input offset voltage by supplying the reference voltage to a signal input terminal and making use of the output of a comparator obtained when the reference voltage is supplied. CONSTITUTION:The reference voltage 6 is first supplied to a signal input terminal 12 of a comparator 2. Then the voltage to be applied to a reference voltage input terminal 13 is successively increased until the output of the comparator 2 is inverted. As a result, the voltage applied to the terminal 13 is held at a level close to the voltage 6. Then this held voltage is compared with a signal input 7. Therefore the reference voltage is controlled with the output of the comparator 2 before comparison with the signal input. Thus the effect of the input offset voltage is greatly reduced.

Title: Casting method of grating for lead storage battery
Inventor: UTSUNOMIYA TSUYOSHI
IPC: B22D25/04
Filed: 1979-02-14
Abstract: PURPOSE: To ease the inflow of molten metal, prevent fins and improve working efficiency by applying coat only in the engraved grooves for casting.  
     CONSTITUTION: After coat 7 is applied over the entire surface of one 1 of a pair of molds, the coat 7 of the other portions is scraped off by using a scraper or the like, leaving the casting groove 2 portions. The other mold opposing to the one mold 1 is also treated in the manner similar to the above. Next, when the both molds are butted, the occurrence of minute clearances 7' as for conventional molds is obviated because of the absence of the coat on the mating surfaces. Thence, when a force- exhaust hole 5 is connected to a suction device and air is removed, the residual air in the casting groove spaces is removed from the venting fine groove around the casting grooves 2, whereby negative pressure is developed. When molten metal is poured at this time, the flow into the casting grooves becomes good and the casting may be done surely.

Abstract: PROBLEM TO BE SOLVED: To reduce a pulse width, improve efficiency, facilitate handling, improve reproducibility and stability, prevent a wavelength conversion crystal from being damaged, and miniaturize a device by forming a mirror at a side near the wavelength conversion crystal for composing a stable resonator with a convex mirror. SOLUTION: The curvature of a resonator mirror 1 with a high reflection factor for a fundamental wave laser beam and a resonator mirror 7 with a high reflection factor for a second harmonic laser beam and the fundamental wave laser beam is of convex surface, and a wavelength conversion crystal 4 for generating second harmonic is subjected to phase matching by changing its angle and temperature for changing the refractive index of the wavelength conversion crystal. The wavelength conversion crystal 4 is placed near the resonator mirror 4 whose curvature is of convex surface.  Then, by appropriately selecting the curvature of a convex mirror and the distance between mirrors, the shape of a beam mode becomes that without any beam waist in a resonator, thus reducing the length of the resonator while nearly identically maintaining the diameter of the beam mode at a stable oscillation region in excitation intensity.
