Title: Shaft sealing mechanism for stratum investigating probe
Inventor: OGURA KIMIO
IPC: F16J15/43
Filed: 1983-03-18
Abstract: PURPOSE:To provide a high level shaft sealing effect all the time by constructing a shaft which is extending through a stratum investigating probe casing in such a manner that the pressure acting upon both sides of a magnetic fluid seal sealing said shaft is nearly equal so as to eliminate a differential pressure across the sides of said seal. CONSTITUTION:A magnetic fluid seal 3 is attached in a position in a stratum investigating probe casing 1 where a rotating shaft 2 is routed in a watertight manner by a lock 5 nut having O-rings 4a, 4b. Said rotating shaft 2 is supported by a bearing 6, and is extended from an output section of a rotary machine 8 such as a motor or generator which are installed in a closed space 7. The closed space 7 is filled with insulating oil such as silicon oil, and a side wall of the casing 1 comprising the closed space 7 is provided with an opening 11 which is closed by a pressure balancing bellows 12. In this manner, since in response to a water pressure P acting upon one side of the seal 3 the bellows 2 deforms to cause the pressure in the closed space 7 to become nearly P, the differential pressure across the sides of the seal 3 is eliminated, resulting in a high shaft sealing effect.

Abstract: PURPOSE:To produce an anodized aluminum magnetic film having excellent intransurface magnetic characteristics by adding nonmagnetic material or magnetic material having low saturation magnetization into the ferromagnetic material and forming a laminer structure in ferromagnetic particles in the fine pores of anodized aluminum. CONSTITUTION:An anodized aluminum magnetic film having intrasurface magnetic anisotropy is obtained by incorporating P element into Co single material or a magnetic alloy essentially comprising Co in fine pores of anodized aluminum. The alloy essentially comprising Co is such an alloy containing >50% compounding ratio of Co, for example, Co-Ni and Co-Fe. The amt. of P in the magnetic material ranges 0.05 - 33atm.%, and particularly, 2 - 10atm.% is preferable. With 2 - 10 atm.% of P, strong intrasurface magnetic anisotropy is obtained in the anodized aluminum plating film. Moreover, by increasing the porosity of anodized aluminum up to 0.3 - 0.7 and specifying the axial ratio of Co-P particle to 0.5 - 10, the dimensional anisotropy of Co-P particle can be reduced to further improve the intrasurface magnetic characteristics.

Title: Error controller
Inventor: HIRASAWA MOICHI
IPC: H04L1/16
Filed: 1981-03-27
Abstract: PURPOSE:To complete decoding within a finite time by eliminating the successive output of ARQ by transmitting the same words twice at a maximum, and correcting absence and a word error sestimated from the word transmitted twice when an error is detected at each time. CONSTITUTION:An input signal from a forward communication path 3 is arryed in a receiving buffer circuit 9 as much as one word, and then an error detecting circuit 10 checks a code error; when no error is found, the output signal 11a of a control circuit 11 goes up to 1, and the output of the circuit 9 is transferred to a receiver 5 through gates 16 and 19. If the circuit 10 detects an error, a signal ARQ is sent to a backward communication path 7 and the output 11a of the circuit 11 goes down to 0 while the 11b goes up to 1, thereby inputting the output of the circuit 9 to a buffer register 4a. When the circuit 10 detects an error in a word resent by the ARQ again, the output 11c of the circuit 11 goes up to the 1 and a deciding circuit 12 compares the contents of the register 4a with those of the circuit 9; bits having coincient logic are outputted as they are, and dissident bits are outputted as absent ones, thus sending a word whose error has been corrected by an error corrected by an error correcting circuit 14 to the receiver 5.

Filed: 1982-03-26
Abstract: PURPOSE:To attain stable oscillating period not affected with the dispersion of a threshold voltage, by deciding the oscillating period depending on the threshold voltage difference of an MISFET, mobility mu and geometrical dimension of the MISFET and a capacitor. CONSTITUTION:The capacitor C is charged up with a power supply voltage VDD via a switch MISFETS1 and the potential at a node N2 is increased. When the potential at the node N2 reaches a certain value VH or over, an output of a Schmitt trigger circuit 12 goes to a high level and the MISFETS1 is switched off, and an S2 is switched on. Then, the charges in the capacitor C are discharged in a prescribed speed at a constant current circuit 11, and the potential at the node N2 is dropped. When the potential of the node N2 decreases to a certain value VL or below, the output of the circuit 12 goes to a low level and the capacitor C is charged again. Then, oscillating signals having amplitude VH-VL are outputted.
