Title: Battery back-up memory device
Inventor: SHIOMI KENJI
IPC: G06F1/24
Filed: 1989-01-09
Abstract: PURPOSE:To obtain a battery back-up memory capable of securing effective back-up information by providing an initialization selecting means capable of selecting the initialization or the non-initialization of the back-up information at the time of the start-up system. CONSTITUTION:When the start-up of the system is accepted, it is decided whether a switch 11 indicates the initialization of the back-up information or not. Then, in the case where an initialization request is present, the back-up initialization information of initialization information 10 is written in a back-up memory 2, and the start-up of the system is completed. On the other hand, in the case where the initialization request is not present, the start-up of the system is completed as it is. Since the initialization/non-initialization can be selected at the time of the start-up of the system in such a way, the security of the effective back-up information becomes possible.

Title: Sound recording/reproducing circuit for tape recorder
Inventor: INOUE SHUJI
IPC: G11B5/027
Filed: 1987-01-07
Abstract: PURPOSE:To here signals before they are recorded on a magnetic tape by recording the signals obtained from a microphone on the tape after delaying them by a prescribed time. CONSTITUTION:The signals converted into digital signals by a 1st voice converting circuit 20 are inputted to a memory circuit 22 and stored here for a prescribed time. The memory circuit 22 is provided with a write terminal 23 and a read terminal 24 connected to an output terminal 21 of the circuit 20. The sound record signals obtained from a microphone 6 at the time of a recording action are stored in a memory circuit 22 which is used for repeating reproduction at the time of a reproducing action. At the same time, the signals read out of the circuit 22 are recorded on a magnetic tape. Thus the sound recording efficiency is improved by using the circuit 22 which is originally used for repeating reproduction at the time of a reproducing action is used also at the time of a recording action.

Title: Column for blood analysis
Inventor: JINNO HIDEKI
IPC: G01N33/72
Filed: 1981-01-08
Abstract: PURPOSE:To hemolyze many blood samples at the same time, by arranging a filter layer absorbed with hemolysis agent to a porous material, in adjacency to separation medium layer used for chromatography and so on. CONSTITUTION:A porous material made of vinyl acetate resin is dipped in 10mul/ ml aqueous surfactant solution, then, dried at 50 deg.C for 3hr in an air bath. This filter layer is pushed into a plastic column horizontally, which is filled with weak acidic ion-exchange resin as a separation medium for measurement of glycosylhemoglobin, and added 200mul buffer solution for elution of glycosylhemoglobin. When 10mul whole blood sample measured by a trippet is put on the filter layer, hemocyte is hemolyzed, and the hemolyzed sample is entered into the separation medium layer to measure the amount of glycosylhemoglobin, followed by taking off a stopper at the bottom of the column. Since the whole blood sample can be used as it is without adjusting the hemolyzed sample as mentioned above, this method is preferable to analyze many samples.

Title: Hydraulic shock absorber
Inventor: KASHIMA MITSUHIRO
IPC: F16K17/04
Filed: 1981-01-09
Abstract: PURPOSE:To prevent variations in a preset damping capability by a method wherein a gain in a preset relief pressure arising from an increase of the temperature of a working fluid is canceled by the pushing force of a compensating means the pressure of which is increased under the heat of the working fluid. CONSTITUTION:In a cylindrical body 12, a cylinder 40 is placed coaxially with a spool 11 and defines a sealed gas chamber 41 therein. The working fluid is expanded with an increase in temperature and its heat causes the pressure inside a gas chamber 9 to increase, so that the hydraulic pressure is raised to force the spool 11 toward the gas chamber 4 side. At the same time, a gas sealed in the gas chamber 41 is expanded under the heat of the working fluid flowing through a passage 42, and the resultant increased pressure of the gas pushes back the spool 11 to the side of an oil reserving chamber 10. As a result, the gains in the pressure due to the temperature increase exerted on both ends of the spool 11 are canceled and, accordingly, the preset pressure for a relief valve 24 is not affected by the increase in the temperatre of the working fluid.

IPC: E02F9/22
Filed: 1982-01-12
Abstract: PURPOSE:To prevent turbulence of a working trace even at a stroke end, by a method wherein, when an arm cylinder reaches at least in the proximity of the stroke end, a boom cylinder stops moving. CONSTITUTION:A control part 50a is provided with a function generator 14a which is used in case a relative angle alpha2 of an arm, not shown, widens from alpha2min to alpha2max through contraction of an arm cylinder (not shown) and a function generator 14b which is used in case the angle alpha2 narrows from alpha2min to alpha2max. A device is constituted such that, when a cylinder, not shown, reaches in the proximity of a stroke end, a boom cylinder, not shown, stops moving. As a result, for example, if the relative angle alpha2 becomes narrower than alpha2min, the function generator 14b enters a stop zone as shown in a characteristic figure and will have a zero output. Thus, a flow rate adjusting mechanism (not shown) will also have a 0 input, a boom (not shown) is brought to a stop a little before the arm cylinder reaches the stroke end.

Title: Multipath separation detector
Inventor: HIOKA NOBUYUKI
IPC: G01S7/40
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To reduce erroneous recognition of pulse trains due to multipaths existing in received radio waves by detecting the pulse trains by removing overlapping and separated multipaths from pulse data. SOLUTION: The received radio waves of a reception antenna 1 are detected as usual by means of a pulse data detecting section 4 as pulse data having a pulse width and pulse arriving time through a frequency filter 2 and a pulse data accumulator 3. An overlapping-multipath discriminator 7 processes the auto-correlation of the detected pulse data and discriminates the presence/ absence of overlapping multipaths from the number of peaks (three or one) of the auto-correlation. A separated-multipath discriminator 5 discriminates as usual whether or not the detected pulse data contain separated multipaths from the difference in arriving time. A pulse train detector 6 detects a pulse train composed only of direct waves by removing the overlapping and discrete multipaths when pulse data contain the multipaths based on the discriminated results of the discriminators 7 and 5.
