Title: Cable television system
Inventor: MIYAZAKI ISAO
IPC: H04B3/46
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To detect movement of a terminal unit which is lent out to a new subscriber's house of a CATV system and to prevent unauthorized viewing. SOLUTION: In a bi-directional CATV system, a center unit 1 transmits a terminal response request command to a terminal unit 2 which is lent out to a new subscriber, and the unit 2 returns a response command to the terminal response request command to the unit 1 side. The unit 1 stores the time which is taken by the response command to be returned as an initial response delay time of the unit 2 in a response delay amount storage database 10. The unit 1 requests the unit 2 to return the response command at each fixed time, compares the time that is taken by the response command to be returned with the initial response delay time, decides that the unit 2 has moved when the difference in both becomes a prescribed time or more, and executes viewing restrictive processing such as stopping of transmitting program data, etc.

IPC: H01L27/092
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To reduce a manufacturing process to an irreducible minimum so as to improve CMOS devices in yield by a method wherein PMOS/NMOS transistors of low threshold voltage are formed at the same time through only a single low-threshold voltage ion implantation process without adding another mask process and ion implantation process. SOLUTION: An element isolation film 11 is formed in the required region of a P-type semiconductor substrate 10, a P well mask pattern 112 is removed, and then a mask 113 is formed so as to enable a region where NMOS/PMOS transistors of low-threshold voltage are formed to be exposed. At this point, an NMOS transistor of low-threshold voltage is formed in a region of the semiconductor substrate 10 where no well is formed. In succession, boron ions are implanted in a low ion implantation method to form third impurity layers 17a and 17b, so as to make the NMOS transistor of low-threshold voltage as low in threshold voltage as prescribed. Then, the mask pattern 113 is removed, and a gate oxide film 18 and gate electrodes 19a to 19d are formed on a structure.

Title: Image forming device management system
Inventor: KOSUGA YASUO
IPC: B41J29/38
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To make easily collectable data even from a remote management- device by constituting a management device so that it can instruct to shift from an energy saving mode to an ordinary mode (or vice versa) in an image forming device. SOLUTION: The management device is composed of a key card display part 101, a card 102, and a key card reading machine 103. In such a composition, in the case an image forming device is shifted to an energy saving mode at the time of collection of data from a collecting device, an energy-saving-mode cancellation command is transmitted to an image forming device connected to the management device. The image forming device thereby cancels the energy saving mode and supplies power to the management device. Actually, because the supply of power only to the management device is enough, complete restoration is not caused, and shift to a mode other than the energy saving mode (an ordinary energy saving mode + a mode for supply of power to the management device) may be allowed.  Also, it makes it possible to inform the image forming device of the finish of the collecting operation and to shift to the energy saving mode again.

CONSTITUTION:A fluorescent lamp discriminating circuit 3 outputs a signal '1' when deciding that the object light is the light from the fluorescent lamp but outputs signal '0' otherwise. The output of a focus detecting photodetecting element 5 to which the object image due to a photographic lens is projected is read into a focus position detecting circuit 6 to output a focus detection signal. This signal is a data signal of the extent of movement of the photo graphic lens to the focus position. This data signal is inputted to not only an input terminal (a) of a data selector 4 directly but also an adding circuit 7 for correction and a subtracting circuit 8 for correction. In accordance with the classification of the lens set to a camera, these circuits for correction add or subtract the extent of correction of the focus position to or from the data signal outputted from the focus position detecting circuit 6.

Abstract: PURPOSE:To provide a titled material which improves the resistance to adhesion and wear by adding specific amts. of Si and Zr to an alloy material of the specific compsn. consisting of Au, Pt, Pd, Ag, Cu and Zn. CONSTITUTION:An alloy material consisting of 9-11wt% Au, 9-11% Pt, 34- 36% Pd, 29-31% Ag, 13-15% Cu, 0.5-1.5% Zn is used as a base material and 0.5-5% Si+Zn is added thereto without changing the compsn. ratio thereof; further 0.01-1% an Fe group metal is added according to need, whereby an improved material for a sliding contact is obtd. The reason for adding the above-mentioned Si and Zn lies in an improvement in the resistance of said alloy material to adhesion; if Si+Zn is <0.5%, no dispersion effect is obtd. and if >5%, the processing of the material is difficult. The Fe group metal is added to improve the resistance to wear; if <0.01%, the effect is not exhibited and if >1%, the effect detrimental to the oxide that acts as a lubricant is developped.
