Abstract: PURPOSE:To enable the formation of a highly accurate superconductor at a low temperature by a method wherein a buffering film is formed on a substrate, and a quadruple compound film composed of Bi-Sr-Ca-Cu-O as a main component is made to adhere thereon to form the superconductor of a layered structure. CONSTITUTION:A quadruple compound film 12 of Bi-Sr-Ca-Cu-O is formed on a base body 11 through a method such as a sputtering method, and a buffer layer 15 is formed at a interface between the base body 11 and the compound film 12. If the quadruple compound film 12 is formed directly on the base body 11, a component element of the base body 11 of semiconductor is diffused into the quadruple compound film 12 to make the film 12 deteriorate in a superconductive property, therefore the buffer film 15 is provided to prevent the deterioration of the film 12. The quadruple compound film 12 is formed into a thin film by depositing a superconductive material on the base body after it is dissolved into supermicro particles such as to be in an atomic state, so that a formed superconductor is substantially uniform in composition and can be formed at a low temperature if it contains bismuth, and furthermore a very accurate superconductor can be obtained through the buffer layer 15. By these processes, an excellent superconductor can be formed into a thin film, so that the superconductor excellent in accuracy can be obtained.

Title: Production of semiconductor device
Inventor: KONDOU TAKEO
IPC: H01L21/8238
Filed: 1979-03-22
Abstract: PURPOSE: To prevent punch through from occurring around a diffusion layer, without providing a margin, by regulating the angle of a peripheral portion of an impurity section, which is surrounded by a semiconductor substrate, by compensation diffusion.  
     CONSTITUTION: Compensation diffusion masks 7 are simultaneously formed in four corners of a P well forming mask 6 which is used to form a N channel FET for a C-MOSLSI, such that each of the masks 7 is quadrilateral. A P well 2 of a rectangular pole is formed by using these masks 7. When compensation diffusion is conducted such that the surfaces of N +  diffusion sections 3, 4 are parallel to each other, the P well 2 and N +  diffusion sections do not come close to each other at their polar portions. As a result, punch through, which occur when a depletion layer is partially connected to a base, can be prevented. Accordingly, the distance between the N +  diffusion sections and P well can be further shortened uniformly. This allows a semiconductor device to be miniaturized, and the degree of integration to be improved.

Title: Magnetic disk device
Inventor: TAKASHIMA YOSHIYUKI
IPC: G06F13/12
Filed: 1990-02-14
Abstract: PURPOSE:To shorten the data transfer time by providing a counter circuit for which the number of transfer data is set by an input/output controller and subtracting the number of transfer data every time data is transferred and controlling the data transfer. CONSTITUTION:When the power source is turned on in the input/output controller of this magnetic disk device, a CPU 4 starts the control of each part. At the time of data transfer to a host computer 1, an SCSI control circuit 3 outputs a control signal REQ to confirm a control signal ACK from the host computer 1 and sets the number of data to be transferred to a counter circuit. The counter circuit 5 subtracts the number of transfer data by the SCSI control circuit 3 every time the data is transferred and outputs the control signal ACK to tentatively stop the data transfer when the number of data reaches 0. Consequently, the SCSI control circuit 3 stops data transfer. Every time a new number of transfer data is set to the counter circuit 5, the SCSI control circuit 3 sends the control signal REQ to confirm the control signal ACK.

Title: Pressure measuring apparatus
Inventor: HIRAMATSU YOUHEI
IPC: G01L19/06
Filed: 1980-03-17
Abstract: PURPOSE:To improve the throttling effect in a pressure measuring apparatus by forming a by-pass passage which changes in volume according to pressure between a throttling mechanism and the instrument pressure-receiving portion so that the volume change on the instrument pressure-receiving portion side corresponding to the pressure change is made larger. CONSTITUTION:A by-pass passage 5 is inserted between a throttling mechanism 3 and a pressure instrument 4. In conventional apparatuses, because the pulsation of the process pressure is passed through the throttling mechanism 3 and directly transmitted to the pressure-receiving portion 4, the pulsation preventing effect is small. On the other hand, if the by-pass passage 5 is inserted, when the pressure pulsation rises, the process fluid passing through the throttling mechanism enters a contact liquid chamber 14 in the by-pass passage, so that the pressure in the pressure instrument portion 4 is prevented from rising. Contrarily, when the pressure pulsation falls, the process fluid in the contact liquid chamber 14 returns through the throttling mechanism 3 to the process parent pipe, so that the pressure in the pressure instrument portion 4 is prevented from falling. Thus, the by-pass passage 5 permits the effect of the throttling mechanism to improve.

When both the electromagnetic discs 2o, 3o are magnetized in this way, the driving force from the driving shaft 2 is transmitted in the following way: electromagnetic disc 2o   magnetic fluid Mo  electromagnetic disc 3o, and the shaft 3 is also rotated in Y direction. When the intensity of the current passing through the coil 4 is adjusted, the magnetic force generating at the respective electromagnetic discs 2o, 3o can be changed, and the power transmitted to the transmission shaft 3 from the driving shaft 2 through the electromagnetic disc 2o can be changed arbitrarily.
