Title: Digital conference service method
Inventor: NOMURA YOSHIO
IPC: H04M3/56
Filed: 1984-05-22
Abstract: PURPOSE:To select speakers accurately and to reduce the occurrence of false switching by registering voice levels of participants and obtaining coefficients which compensate differences of voice among participants and attenuation quantity among lines and compensating voice levels with said coefficients. CONSTITUTION:Average values of voice levels of participants are registered in a voice recording table circuit 10, and the correction coefficient of the participant having a maximum voice level is defined as 0 and differences of voice level of individual participants are calculated as correction coefficients by a voice level correction coefficient calculating circuit 11, and calculated correction coefficients are held in a correction coefficient holding table circuit 12. When a voice is inputted to an intra-frame speaker detecting circuit 4 and an intra-frame speaker is determined, maximum value detection is performed after correction coefficients of individual participants of a COT circuit 12 are added to voice sample data of them. Then, differences of voice level of participants and attenuation quantity of used lines are compensated. Thus, speaker selection is performed for the participant, whose voice level inputted to the circuit 4 is reduced, in the same conditions as the participant whose voice level is raised.

Title: Self-controlling valve
Inventor: TAKEYAMA TOMOKAZU
IPC: G05D16/04
Filed: 1979-08-13
Abstract: PURPOSE: To settle a trouble occurring at the time of an abnormal flow of a fluid, by using the valve of such a design that the fluid is allowed to flow only when the difference between entry side pressure and exit side pressure of the fluid becomes within the set range and that opening and closing of the valve is self-controlled by the pressure of the fluid itself.  
     CONSTITUTION: A lift type check valve 9 is pushed up by a gas coming in from the bottom, and a valve rod 13 connected to top and a sliding valve 22 are also pushed up at the same time. In the position where the lateral lattices 16 and 17 of the sliding valve 14 and their piercing holes 19 and 20 are set together with a piercing hole 23 of the valve body 22, that is, when the check valve 9 is in the condition of floating at an intermediate height, a fluid smoothly flows from an inlet 5 to an outlet 8. When the entry-exit pressure difference of the fluid becomes excessively large, the check valve 9 and the valve body 22 are furthr blown up causing a shift of the positions of the piercing holes 19 and 20 from the positions of the piercing hole 23 so that the flow is stopped, and conversely, if the pressure difference becomes excessively small, both the check valve 9 and the sliding valve 14 are also shut off. Only when the pressure difference becomes within a set range in which weights of the two valves and the force of blowing up the check valve are in equilibrium equilibtated, the fluid is allowed to flow automatically.

Title: Controller of frequency converter
Inventor: NEMOTO YOUICHI
IPC: H02M7/515
Filed: 1984-05-24
Abstract: PURPOSE:To enable to stably operate without intermittently flowing a DC current by no increasing a DC reactor even at a load communication time by controlling a gate pulse of a load commutation inverter in response to a load impedance. CONSTITUTION:The outputs of an AC/DC converter 11 and a current/voltage converter 12 are input to a divider 13 to obtain a load impedence. When the obtained impedance is high, the output (g) of the divider 13 increases, and the phase of a gate pulse (d) is advanced from the normal state time. Thus, a DC current is not intermittently flowed even at a light load time by advancing the gate pulse phase of a load commutation type inverter, thereby performing a stable operation.

Abstract: PURPOSE:To produce castings of which the outside surface is resistant to abrasion and the core part is strong and tough easily and inexpensively in the composite castings of cylindrical or columnar shapes, by forming a high hardness layer contg. WC particles on the outside surface of the outer layer to one body. CONSTITUTION:Molten metal for an outer layer is cast into a rotary metal mold 2 from a ladle 4 through a trough 5 or the like, whereby the outer layer 8 of a composite roll is cast centrifugally. In the stage of casting the layer 8, WC powder 6 which is plated with Ni, Ni-P, Ni-B, Cu, etc. and is in an ordinary temp. or is preheated to proper temps. is added thereto. The WC powder added to the molten metal for the outer layer separates by gravity during the time  until the outer layer solidifies on account of a difference in specific gravities  under exertion of centrifugal forces in the molten metal for the outer layer, thus forming a high hardness layer 7 contg. the WC particles on the outside surface of the outer layer in one body. When the layer 8 solidifies, molten metal for a core material consisting of a mild strong and tough material is cast therein in the manner similar to that in the prior art, whereby the layer 8 and the core part as well as neck parts 9 are melt-stuck to one body.

Filed: 1987-04-30
Abstract: PURPOSE:To realize input/output protection by checking whether or not a privileged processing request is effective in an interruption processing routine when the privileged processing request is generated and a primary storage means is set. CONSTITUTION:A flip-flop 19 indicates a privileged processing request flag and a register 22 is inhibited from being accessed except in an interruption processing routine wherein the flag is not set. On the other hand, when the privileged processing request is generated and the flip-flop 19 is set, a return address is checked in the interruption processing routine to check whether or not the privileged processing request is effective. When not, this is canceled to realize the input/output protection. Consequently, a protection mechanism is realized which is never reset by an application program.
