Abstract: PURPOSE:To contain a EPROM without newly increasing the number of external terminal in a one-chip microcomputer in which the number of external terminal (the number of pins) is limited. CONSTITUTION:Various kinds of signal outputted by a general use EPROM writer 101 are inputted through an address signal line (15 bits) 107 to an address time-division circuit 102, and time-division processed into 8 bits by the control signal of a clock generating circuit 103. A signal supplied through an output signal line 108 of an address time-division circuit 102 is inputted through an external input terminal 118a of the one-chip microcomputer to an inner address latch circuit 104. At that time, the signal is restored to an address signal 109 of 15 bits by the control signal of the clock generating circuit 103, and becomes the address signal of an contained EPROM 106.

Title: Wavelength converting element
Inventor: MAEDA HIDEO
IPC: G02F1/37
Filed: 1991-05-09
Abstract: PURPOSE:To emit short-wavelength light with efficiency even when fundamental wave light slightly varies in wavelength. CONSTITUTION:A nonlinear optical medium 2 consists of plural domains D1-Dn whose pitch is an odd multiple of the coherence length of the short-wavelength light and the respective domains D1-Dn are inverted in polarizing direction basically by turns, but at least one domain Di among the domains D1-Dn has the same polarizing direction with its one adjacent domain Di-1 and is inverted in phase at this domain. The total intensity of the short-wavelength light increases by phase matching up to the domain Di, but decreases behind the domain Di as a border, so that even when the fundamental wave light varies in wavelength, the projection intensity of the short-wavelength light becomes nearly equal eventually regardless of the wavelength variation.

Filed: 1979-10-17
Abstract: PURPOSE:To prevent the syneresis of an electrolyte whose main component is zinc chloride, and reduce the internal resistance of a battery by adding to the electrolyte an acetal of a polyvinylalcohol as a starching agent. CONSTITUTION:A separator 7 made of nonweaved cloth such as polyethylene or polyester, is interposed between a zinc negative-electrode 5 and a positive electrode 6 whose main component is manganese dioxide. The separator 7 holds an electrolyte 8 whose main component is zinc chloride with increased viscosity; an acetal of a polyvinlalcohol is used for increasing the viscosity of the zinc chloride. For example, 25% zinc-chloride solution is added with 3wt% of vinyl-acetal fibers, and the mixture is heated at 90 deg.C for 10min to dissolve the vinyl acetal and increase the viscosity of the solution, an electrolyte 8 being prepared. Consequently, the electrolyte 8 containing the dissolved vinyl-acetal is firmly fixed between the negative electrode 5 and the positive electrode 6, the syneresis of the electrolyte is avoided, and the electrolyte 8 doesn't excessively migrate into the positive electrode. Thus, a battery with a small internal resistance which has little variations in its discharge performance can be obtained.
