Title: Controller for dynamic memory
Inventor: MAEDA TAKESHI
IPC: G11C11/401
Filed: 1991-01-25
Abstract: PURPOSE:To speed up the access to a packaging region by prohibiting the access to the unpackaging region of a dynamic memory and to easily monitor the low address strobe signal pulse width in a high-speed access mode. CONSTITUTION:A memory system 1 outputs an ID code 30 indicating the packaging state of a memory chip to a packaging/unpackaging decision section 29. A memory control signal forming section 11 and a memory upper address holding section 10 are put into an operation inhibition state and maintain the state of the memory control signal of one cycle before if the result 31 of the decision is unpackaging. The no-weight high-speed memory access is executed if the memory upper addresses coincide when the memory access to the packaging region arises next. The above-mentioned memory control signal forming section 11 negate all the low address strobe signals by a refresh request signal 34 outputted from a refresh request signal forming section 26 and, therefore, there is no need for monitoring the pulse width thereof.

IPC: F16F9/50
Filed: 1991-01-25
Abstract: PURPOSE:To keep the riding comfortability unchanged by maintaining the passive attenuation force nearly constant even in cases where the temperature of an operating oil varies and the viscosity thereof is resultantly varied. CONSTITUTION:A variable throttle 24 is provided in piping 40 between a pressure control valve 20 and an oil-pressure cylinder 18 while, on the other hand, a second variable throttle 26 is provided in piping 48 between a cylinder chamber R of the oil-pressure cylinder 18 and an accumulator 28. An oil temperature signal T from an oil temperature sensor 32 mounted on an oil pressure pump 58 is supplied to a controller 34 at which judgement is made of the temperature(t) of the operating oil. When the oil temperature(t) is lower than a threshold value, the controller 34 operates to cause a decrease in the attenuation constants of the variable restrictors 24, 26. When the oil temperature(t) is higher than the threshold value, the controller 34 operates to cause an increase in the attenuation constant of the variable restrictors 24, 26. By this, the changed attenuation-force portion attributable to the change in viscosity of the operating oil resulting from a change in the oil temperature is substantially offset by the adjusted attenuation-force portions of the variable restrictors 24, 26.

Abstract: PURPOSE:To achieve a rise in sensitivity and a higher response speed by forming a tip part curved in an optical fiber sensor in which light is introduced to a reagent layer through an optical fiber to measure a nature of an object to be measured by light obtained from the reagent layer. CONSTITUTION:An optical fiber 100 comprises a long-sized core 101, a clad 102 and a jacket 103 and the tip part 110 thereof is formed so curved as to make a part of a ball. A reagent layer 104 and a permselective film 105 covering the layer is formed on a spherical face of the tip 110. Here, the reagent layer 104 contains a material which causes a sort of optical change in reaction with a material to be measured and the permselective film 105 has functions to block material other than that to be measured and a reaction interfering substance from reaching the reagent layer 104 from outside and to prevent the reagent layer from spilling out. In this manner, a surface curved to hold the reagent allows a coating of a larger surface area with an even thickness for the reagent layer 104 and the permselective film 105, thereby realizing a higher sensitivity and a higher response speed.

Abstract: PURPOSE:To perform burnishing work following shaving work with no necessity for rearrangements, by providing a burnishing work part, having no serration, successively to a serration part which performs the shaving work along the tooth trace direction of each tooth in a cutter. CONSTITUTION:A shaving cutter 21, engaging its serration part 22a with a gear to be cut with a crossing angle being given, performs shaving work of the gear to be cut by forcedly rotating either one of the cutter or the gear to be driven. Next the cutter 21, relatively moving the gear to be cut in a tooth trace direction and changing an engaging position, engages a burnishing work part 22b with the gear to be cut. And the cutter, similarly forcedly rotating the gear to be driven, performs burnishing work of the gear after its shaving work by the burnishing work part 22b. Here the shaving work causes a sharpened portion to be left in a tooth surface of the gear to be cut 23 in the crossing part of a cutting locus of a serration cutting edge, but the cutter, burnishing the sharpened portion by the burnishing work part 22b, improves both tooth surface roughness and also tooth surface strength.
