Title: Detection system for addressing exception
Inventor: SHIBATA HIDEAKI
IPC: G06F21/62
Filed: 1983-12-19
Abstract: PURPOSE:To cope with a flexible system constitution which has a small amount of hardware and has a hardware private area distributed in a main storage, by providing an addressing exception discriminating circuit, an access validity bit, etc. CONSTITUTION:In case that a new main storage key is registered in a key storage KS110, the address of a corresponding block on a main storage device MS is set to a main storage reference address register SAR103. The main storage key is set to a register KSWD126. At this time, the access validity bit (bit V) indicating whether reference of a program to the block is valid or not is added to the main storage key in the KS110. The set main storage key is compared by a comparing circuit 122, and simultaneously, the bit V is inputted to an addressing exception discriminating circuit 123. The circuit 123 discriminates whether the bit V is ''0'' or ''1'', and if it is ''0'', an addressing exception signal is outputted to supress reference to the main storage. Thus, this system can cope with the flexible system constitution.

Title: Die for extruding aluminum and method for nitriding the same
Inventor: OHIRA SHIGEO
IPC: B21C25/00
Filed: 1995-08-25
Abstract: PROBLEM TO BE SOLVED: To produce a die for extruding free from breaking at the time of extruding by forming a white layer and a nitrogen diffused layer of which thicknesses are specified. SOLUTION: This die is the one in which a white layer having 4 to 8μm thickness is formed via a nitrogen diffused layer having 100 to 150μm thickness on the surface of a die steel for extruding to be contacted with an aluminum alloy as the material to be extruded. The ratio of (the area of the white layer+ nitrogen diffused layer)/(the total area of the cross sections) is preferably regulated to <=70% as for the cross section of the die parts vertical to the extruded direction. In nitriding treatment, the die steel is held to 300 to 520 deg.C in a gaseous fluorine atmosphere and is next held to 450 to 520 deg.C in an NH3 -RX gaseous mixture atmosphere. Furthermore, in the case the white layer is extinguished by wear, renitriding treatment is executed under the similar conditions.  Thus, the breaking of the part small in the cross section such as the mandrel part small in the cross secton is prevented to prolong the service life of the die.

Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To provide a reversing inhibition device capable of preventing the generation of breakdown even if the excessive rotary driving force due to the working force from a load side is generated. SOLUTION: A ratchet gear of a ratchet mechanism for checking the rotation of a screw member is formed freely to be turned without integrally fixing it with a screw member, and when the action force is applied to this screw member from a load side, the magnetic force by an electromagnet is generated by existence of this action force so as to conclude the checking.

Title: Amplifier for antenna
Inventor: YOSHIDA AKEMASA
IPC: H03G3/20
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To suitably output a high frequency input signal to a tuner respectively in the case that an antenna reception terminal power is strong or weak. SOLUTION: A detection circuit 14 detects an RF input signal from an antenna and outputs a DC signal in response to an antenna receiving end power to a 1st changeover on/off circuit 15. When a voltage of the DC signal is higher than a prescribed threshold voltage, the 1st changeover on/off circuit 15 is closed and a 2nd changeover on/off circuit 16 is open. Thus, only a signal via an attenuator 12 or the like is outputted to a tuner. When the voltage of the DC signal is a prescribed threshold voltage or below, the 1st changeover on/off circuit 15 is open and the 2nd changeover on/off circuit 16 is closed. Thus, only a signal via an amplifier 13 or the like is outputted to the tuner.
