Filed: 1985-02-26
Abstract: PURPOSE:To operate an operating means with minimum energy loss by always deciding unequivocally the number of operating means which are operated in parallel according to the increase/decrease of load on the basis of the upper limit value of an available load range for the number of selected operating means. CONSTITUTION:A tank 1 stores a fluid W at a fixed level L and contains an input pipeline 2 and a discharge pipeline 3. Plural pump devices 5 constitute the operating means between the pipeline 2 and an introduction pipeline 4. These devices 5 are controlled by controllers 6. The operations of devices 5 are selected by an operating unit number switching means 7 via a total load controller 9 and an arithmetic means 10. If the present total using load is set at A with four working operating means, the number of operating means are increased by one when the load increases from A1 and reaches the operable upper limit value A2 on a line B4. At the same time, an action point also moves to a point A3 on a line B5. If the load is reduced, the working means are decreased by one and then switched to the original four units at a point A4.

Title: Mechanical characteristic measuring device for thin film
Inventor: KIMURA MASATO
IPC: G01N3/00
Filed: 1992-02-25
Abstract: PURPOSE:To enable accurate measurement by providing a groove in the center of supporting mechanisms that have been provided at two places on a test-piece table, so that an indenter can be easily moved to the center of the supporting mechanisms. CONSTITUTION:An indenter 5 is moved by a positioning part 8 above the groove 9 that has been provided at the center of two supporting mechanisms 2 on a test-piece table 3, and the indenter 5 is pushed into the groove 9 by operating a driving part 6. By adjusting the end position of the indenter 5 by means of the positioning part 8 so that it can be brought to the center of the V-shape of the groove 9, the positioning of the indenter 5 to the mechanisms 2 is accurately carried out. By operating the driving part 6, the indenter 5 is lifted up, and a test piece 1 whose modulus of longitudinal elasticity is to be obtained is mounted on the mechanisms 2, and then the indenter 5 is lowered. The pressing load at that time and the deflection of the test piece 1 are measured by a load converter 4 and a displacement gage 7 respectively. The modulus of longitudinal elasticity of the test piece 1 is obtained on the basis of the relation-ship between the pressing load and the deflection, the thickness of the test piece 1, the width thereof, and the distance between mechanisms 2. Even in the case where a thin film is formed on the test piece 1, by measuring the relationship between the pressing load and the deflection, the modulus of longitudinal elasticity of the thin film can be obtained.

Title: Electron-tube cathode
Inventor: WATABE KEIJI
IPC: H01J1/20
Filed: 1982-03-08
Abstract: PURPOSE:To obtain an electron-tube cathode with a high current density by increasing the conductivity of an oxide layer, and sufficiently activating the oxide layer by coating a base body principally consisting of nickel with an electron-discharging matter prepared by mixing an alkaline-earth-metal oxide with Ni powder, Co powder or an alloy powder consisting of Ni and Co which has a specific grain diameter. CONSTITUTION:In a cathode made by coating a base metal principally consisting of nickel with a layer which is made of an alkaline-earth-metal oxide and contains barium, the alkaline-earth-metal oxide is combined with at least one kind of powder which has a grain diameter of below 0.3 micron and is chosen from among nickel powder, cobalt powder and an alloy powder consisting of nickel and cobalt. If the grain diameter of the nickel powder is larger than 0.3 micron, the nickel powder is unevenly dispersed in the oxide layer, and a current easily flows in a local part of the oxide layer. Therefore, it is not desirable that the grain diameter of the nickel powder is larger than 0.3 micron. In addition, it is preferred that the amount of the nickel powder added is within the range of 0.1%-10%.

Title: Substrate bias generating circuit of semiconductor storage device
Inventor: SAKURAI SEISHI
IPC: G05F3/20
Filed: 1993-02-26
Abstract: PURPOSE:To provide a quickly responding substrate bias circuit by providing a signal control means, which generates more than two groups of delayed signals controlling a bias generating means provided in a detection circuit, based on the difference in detection levels. CONSTITUTION:When a substrate bias level VBB slowly rises, an inv 12, which has a low circuit threshold value VTH among two delay circuits 26 and 27, senses a monitor node N2 as an 'H' and a node N4 becomes an 'L'. Thus, a nand 1 becomes an 'H' and a ring oscillator 12 restarts. If the VBB quickly rises, the node N2 level goes up, the inv 12 is turned on and an inv 7 is also turned on. Since the node N2 transits from an 'L' to an ''H'', the circuit constitution of the circuit 27 has a faster transmission speed. Thus, the level of a node 3 becomes 'L' faster than the level of a node 4 and the ring oscillator 12 is made operable. Moreover, in order to turn off the oscillator 12, it is determined by the delay circuit which has a slower input to the nand 1. Thus, it becomes a conventional speed.

Title: Data transfer method
Inventor: SAWARA YASUYUKI
IPC: G06F13/00
Filed: 1994-03-09
Abstract: PURPOSE:To discriminate a transmission node which transmitted a synchronous packet and to prevent the unwilling interruption of synchronous communication at the time of performing the synchronous communication of data requiring a real time processing such as video signals and audio signals, etc., among plural equipments. CONSTITUTION:In this data transfer method, the node identifier 5 of the transmission node for transmitting the synchronous packet is added to a data header 2 inside the synchronous packet. A reception node instantaneously discriminates a node which transmitted the synchronous packet just by looking at the node identifier of the transmission node included in the received synchronous packet. Also, by the fact that the transmission node is turned to a protective state at the point of time of receiving more than one continuation requests and is turned to a protection cancellation state at the point of time of receiving stoppage permission for more number of times than the reception of the continuation requests, a transmission stoppage request from the other node is denied in the protective state and the transmission of the synchronous packet is not stopped.

Title: Reduction and conversion method for picture
Inventor: WAKABAYASHI KAORI
IPC: H04N1/393
Filed: 1986-02-25
Abstract: PURPOSE:To avoid deterioration in picture quality by deciding thin lines that have a risk of disappearance and preserving these thin lines on a converted picture to avoid disappearance of said lines. CONSTITUTION:Reference picture elements P(m, n), P(m+1, n), P(m, n+1), P(m+1, n+1) and P(m+2, n) are available for coordinates Q(i, j). While the picture elements P(m, n), P(m+1, n), P(m+2, n), P(m+1, n+1) and P(m+2, n+1) are available for coordinates Q(i, j+1) respectively. Those reference picture elements are used to the Q(i, j) set in an area 1 and a conditional equation 1 decides the presence or absence of vertical thin lines. While a conditional equation 2 decides the presence or absence of oblique lines. If one of both equations 1 and 1 is satisfied, the presence of thin lines is decided and the value of P(m+1, n) is substituted for the Q(i, j). Then the absence of thin lines is decided when both equations 1 and 2 are not satisfied and the value decided by a conventional converting method is substituted for the Q(i, j). Thus disappearance of lines is avoided for reduction/conversion of pictures. It is also possible to preserve the horizontal/vertical thin lines and the oblique thin lines even in the case of vertical reduction/conversion.
