Abstract: At a heat treatment temperature in a reducing atmosphere of Ar and H.sub.2, a precursory film of V.sub.2 O.sub.5 is reduced into a VO.sub.x film with the heat treatment temperature selected in a predetermined temperature range between 350 .degree. C. and 450.degree. C., both exclusive, to control a resistivity of the VO.sub.x film, where x is greater than 1.875 and less than 2.0. The VO.sub.x film is not susceptible to a metal-semiconductor phase transition inevitable in VO.sub.2 at about 70.degree. C. and is excellent for use in a bolometer-type infrared sensor. When reduced at 350.degree. C. and 450.degree. C. the resistivity and its temperature coefficient of the VO.sub.x film at room temperature are 0.5 and 0.002 .OMEGA. cm and -2.2% and 0.2% per degree Celsius.

Abstract: A plurality of physical registers greater in number than can be addressed by instructions are provided. The physical registers are divided into a plurality of partial groups or windows. Each of the physical registers is specified by a physical register number determined by a combination of the number of the window and a register number contained in the window. The window number is indicated by a current floating point window pointer stored in a current floating point window pointer register. In executing a vector calculation program having repetitive loops of an instruction sequence, the window is changed for each loop by changing the value of the current floating point window pointer. Vector data to be calculated at the i-th loop is read from a main memory at the loop before the i-th loop.

Abstract: List operation on a vector in which the number of an element of a vector operand is represented by an element of another vector operand is to be performed with a general-purpose computer system having no vector registers. List vector elements are read out from a memory by adding at addresses determined sequentially by adding by adding values of a request vector increment register to a list vector address. A value resulting from the bit shift of the element is stored in a second operand increment register. A second vector element is read out from the memory at the address corresponding to a value resulting from addition of the content of the second operand increment register to the second operand initial address register, the element being then stored at the memory location of the address given by a value resulting from the addition of the value of the first operand vector increment register to the first operand address.

Abstract: A lead wire holder including a first holding member and a second holding member. The first and second holding members are interconnected so that both can be folded and put together through a connecting portion. The holding members are provided on the inside thereof with opposed lead wire insertion recesses mounting legs for mounting the holder to a printed circuit board project downwardly from the lower end surface of either or both of the holding members. Elastic tongue portions for elastically holding lead wire are formed from a part of the wall portions of the lead wire insertion recesses. Narrow recesses are disposed on the lower end surface and extend from the insertion recesses, so that the insertion end of each lead wire is restricted when its coated end abuts against with the narrow portions. It is thereby possible to let downwardly projecting cores of the lead wires have a uniform projecting length.

There is disposed a lateral fitting groove having an opening at the front surface. The fitting groove is provided with indentations. The pointer has a fitting portion engaging with the fitting groove on its back surface and the fitting portion has protrusion engaging with one of the indentations.

Abstract: A relief and make-up valve assembly is connected to first and second fluid pressure passages in a fluid pressure device. The valve assembly includes a housing of a hollow cylindrical form which communicates with the passages, a valve axially movable in the housing, a piston partitioning the interior of the housing into a low pressure chamber and a back pressure chamber, and a plunger biased by the piston against the valve to move the valve to an opened position away from a valve seat. The valve assembly controls the level of pressure in the first pressure passage by unseating the valve to relieve a preselected pressure from the first pressure passage or alternately to build up a pressure therein.

Abstract: A hydraulic actuator comprising a pair of pressure oil chambers each of which has a cushioning port, the two cushioning ports being connected to each other through a cushioning means. The cushioning means includes a pair of cracking valves whose closing pressure is lower than its opening pressure and a pair of restricting means for restricting the flow of a pressure oil provided with regard to said cracking valves. This structure permits an output means for the actuator to be stopped smoothly as a result of fully absorbing the inertial energy that accompanies the output means.
