Filed: 1985-02-19
Abstract: PURPOSE:To increase the number of degrees of freedom of system configuration by using asynchronous free running shift registers to constitute input, output, and branch data transmission lines and discriminating whether data is branch data or not to give data to transmission lines. CONSTITUTION:Data inputted to an input data transmission line 101 is given to a selective branch control part 104 through the transmission line 101, and normally, this output data is given to an output data transmission line 102. In this case, a branch discriminating part 105 is provided, and a branch condition is set preliminarily to this part 105 and is compared with inputted data. If they coincide with each other, data is discriminated as branch data, and this discrimination result is reported to the control art 104, and output data is controlled to be given to a branch data transmission line 103. Transmission lines 101-103 are constituted with asynchronous free running shift registers to have the data buffer function.

Patent JP-S56129814-A (JP)
Title: Micro-flowmeter
Inventor: KASAI YOUZOU
IPC: A61B5/20
Filed: 1980-03-14
Abstract: PURPOSE:To make a device so inexpensive to permit its throwaway by a method  wherein periodic variations of the liquid surface of a liquid in a vertical container  between the lower and upper limits in a siphon tube are detected and transmitted  so as to compute and display a signal indicating the flowing amount corresponding  to the change of signal and time. CONSTITUTION:The liquid surface l is gradually raised as a liquid is introduced from a port 3. When the liquid surface l reaches the upper limit lH of a siphon tube, the liquid is discharged via the siphon tube 4 to the outside, and the discharging continues until the liquid surface returns to the lower limit lL of the siphon. The discharging stops at this time, so that the liquid surface is again gradually raised. The liquid surface periodically repeats going up and down between the lower limit lL and the upper limit lH. The number of ups and downs of the liquid surface is counted by a microcomputer 8. Since the amount of a liquid discharged at one time has been measured and inputted to the microcomputer, the integrated liquid amount can be computed. If this amount is divided by the time required, the flow amount is obtainable, and the value is displayed on a device 9.

Abstract: PURPOSE:To enable the rotation of a cultivating device in both normal and reverse directions, simplify a cultivating operation mechanism, and eliminate an erroneous operation by operating a change lever from the operating gear position of a traveling gear stroke to a cultivation changeover stroke at the time of cultivating operation by means of a cultivating device. CONSTITUTION:A traveling gear stroke 3 is provided on a change lever 2 for changing the traveling speed of a body to an operating speed suited to a cultivating operation and to a road traveling speed which is higher than said operating speed. Further, a cultivation changeover stroke 5 which can change the rotation of a cultivating device both in normal and reverse directions by the operation of the change lever 2 is also provided. The change lever 2 can be changed from the operating gear position 6 of the traveling gear stroke 3 to a cultivation changeover stroke 5 for a cultivating operation. By this structure, a power- transmitted rotation of the cultivating device at the time of high speed operation can be prevented enabling a safe cultivation, while eliminating pulling interlocking mechanism as was required in the conventional device, to simplify an operating mechanism while eliminating an erroneous operation.

IPC: F25B9/00
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To improve the stability of freezing temperature by adjusting a flow rate supplied to the discharge port of a compressor from the high temperature end part of a pulse pipe to be larger than that supplied from the discharge port of the compressor to the high temperature end part of the pulse pipe by a flow rate adjusting means. SOLUTION: A fluid in a pulse pipe 12 is compressed and expanded under pressure vibration from a compressor 10 as well as from a passage 15 and a flow rate adjusting means 16. Further, a flow rate 16b flowing to the left part from the right part of the passage 15 is set so as to be larger than a flow rate 16a flowing in an opposite direction, that is, to the right part from the left part of the passage 15. Therefore, a clockwise circulating flow can be supplied in a closed circuit comprising the passage 15, a heat regenerator 11 and the pulse pipe 12, and a counterclockwise circulating flow, which results in a temperature change can be avoided so that the stability of a freezing temperature can be effectively improved.

IPC: C21D1/32
Filed: 1978-03-23
Abstract: PURPOSE:To utilize effectively heat energy by heat exchanging the high temperature gas inside the inner cover during cooling process with the low temperature gas during the early heating process. CONSTITUTION:The gas inside the inner cover of the annealing furnace B during cooling process enters into the heat exchanger 18 through the pipe 16a and the valve 17a, then passes through the valve 17b to the gas cooler 19a, and then goes back again to the annealing furnace B through the valves 17c and 17d by the circulating fan 20a. On the other hand, the gas of the annealing furnace A during early heating process goes into the exchanger 18 from the inner cover 4 through the pipe 16b and then the valve 17e, where it is heat exchanged with the high temperature gas of the annealing furnace B, and then goes back again to the annealing furnace A through the valve 17f, the circulating fan 20b, and then the valves 17g and the 17h. Thus, the time required for each process can be shortened and energy required for heating can be greatly reduced.

Abstract: PURPOSE:To inhibit the migration of silver, by carrying out laminate molding in such a manner that the uppermost surface layer is formed by a prepreg obtd. by impregnating a substrate with varnish obtd. by adding an epoxy resin to an oil-modified phenolic resin and drying it, in the production of a phenolic resin laminated sheet. CONSTITUTION:A paper substrate such as kraft paper is treated with a water-soluble phenolic resin (e.g. phenol/formaldehyde precondensate), impregnated with an oil-modified phenolic resin (e.g. tung oil-modified phenolic resin) and dried to obtain a prepreg. Further, a prepreg is prepd. by impregnating a substrate with varnish obtd-by adding 10-50wt% epoxy resin (e.g. bisphenol type epoxy resin) to an oil-modified phenolic resin, and drying it. The prepregs are laminate- molded in such a manner that the varnish-impregnated prepreg forms the uppermost surface layer, thus obtaining the desired laminated sheet. When an electrically conductive material mainly composed of silver is used for the laminated sheet and a circuit having a narrow pitch is formed, silver is prevented from migrating.
