Title: Carburizing treatment for austenitic metal and austenitic metal product using the same
Inventor: TAWARA MASAAKI
IPC: C23C8/02
Filed: 1995-04-13
Abstract: PURPOSE: To improve surface hardness without deteriorating strength and corrosion resistance by holding an austenitic metal in a heated state under a fluorine type gas atmosphere and then carburizing it at specific temp. CONSTITUTION: The austenitic metal, such as austenitic stainless steel, is held for about ten to several tens minutes in a heated state at about 250-450 deg.C under the atmosphere of fluorine type gas, such as NF3 and BF3 . By this treatment, a Cr2 O3 -containing passivating film formed on the surface of the austenitic metal is changed into a fluorided film. Subsequently, the temp. of the austenitic metal itself is set at <=680 deg.C and carburizing treatment is performed. By this procedure, the surface layer between the surface and a position at a depth of 10-70μm from the surface, is hardened by the infiltration of carbon atoms, and a carburized and hardened layer is formed. The hardness of the carburized and hardened layer is about 700-1050 (HV) by micro-Vickers hardness. This carburized and hardened layer is free from coarse chromium carbide grains.

Abstract: PURPOSE: To obtain a foamed molded article capable of omitting expansion process in molding in a mold and gradual cooling process, having improved heat-resistant creep, mechanical properties, surface gloss, and high quality, by using foamable particles having a specific particle structure.  
     CONSTITUTION: A high-quality foamed molded article is obtained by using globular foamable particles having the surface with a smoothness degrees ≤1.05, a magnification of expansion D about 20W40min times, a damping factor T of air pressure  introduced in the particles  by pressure in a range shown by the formula (1/1500W1/ 2500)D, namely expansion ability ≥1.3 times, and improved gloss by molding in a mold without troublesome process control and condition control. Previously expanded particles are obtained by impregnating crosslinkable polyethylene resin particles with a blowing agent and putting the particles in such an atmosphere that the blowing agent existing in the surface layer of the particles vaporizes away and raising the temperature gradually in such a way that excess stress is not produced on the surface layer parts of the particles when the expanded particles with low magnificiation of expansion are processed into foamed particles with high magnification of expansion.

Abstract: PURPOSE: To enable accurate measurement while realizing high accurate gauging even in the case of including fractions by an arrangement wherein the esult gauged by a rotary wheel is calibrated by detection output from a separate reference mark detector.  
     CONSTITUTION: A distance between the first marking device 1 and the sencond marking device 2 is precisely set to L, and these devices 1, 2 put marks on a gauged line W at the same time when a mark control 4 is operated. Upon movement of the line W, a mark detector 3 detects the marks. On the other hand, a gauge 5 consisting of a rotary hweel measures a moved length of the line w continuously and a pulse generator transmits pulses. This pulse signal is applied to a gate circuit and the gate is opened or closed by an output signal from the mark detector 3. An output signal of the gate is supplied to a line length calibration circuit 8 to compensate an error by the gauge 5 and thus calibrated result is displayed on an indicator 9.

Title: Raw/secret switch communication system
Inventor: ITOGA TOMOHIRO
IPC: H04L9/36
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To prevent large noise that is produced if a modulation signal is outputted from a raw communication system as it is when voice is not correctly restored because the state of a transmission path that sends a voice signal is bad. SOLUTION: Voice is switched to raw communication and secret communication in half duplex, raw voice is sent as it is and secret voice is modulated and then sent. A receiving signal is demodulated by a demodulating part 4 of a secret communication system, concealed digital data is interpreted by an interpreting part 5 and restored to an analog voice signal by a voice decoding part 6, and secret voice is outputted. In such cases, when an synchronous deciding part 7 decides that a voice signal is not correctly restored, a receiving raw/secret switching part 8 switches it to a raw communication system and outputs raw voice. When a deciding part 10 decides that a receiving signal is a modulation signal of secret voice, a volume adjusting part 11 of the raw communication system reduces voice and outputs a modulation signal.

Filed: 1994-04-27
Abstract: PURPOSE:To obtain a pulley whose effective diameter is variable, by composing each pulley wheel with a hub, plural arms extending outward from the hub, and an outer peripheral ring installed at the outer ends of the plural arms. CONSTITUTION:A pulley 10 is composed of a pair of pulley wheels 12 and 14 having arms 16 and arms 18 crossing each other. The arms 18 of the pulley wheel 14, and the arms 16 of the pulley wheel 12 are formed integral with a hub 22 and a hub 20 respectively. The pulley 10 is installed on a shaft 29 through a bush 28. The hubs 20 and 22 are pressed in the directions separating each other by coil springs 32 fitted to the spline tubes in the hubs 20 and 22. Since the outer peripheral edges of the pulley wheels 12 and 14 are approached each other when the coil springs 32 are extended, the effective diameter of a belt installed on the pulley 10 is increased. The effective diameter of the pulley is decided by the tensile force of the belt operating to the pulley 10. In other words, the effective diameter of the pulley is decided by the condition the tensile force of the belt is balanced with the extending force of the coil springs 32.

Title: Building panel
Inventor: SUGANO YOSHIHIKO
IPC: E04F13/18
Filed: 1995-04-14
Abstract: PURPOSE: To prevent a decorated surface from being strained and protect a panel from being separated by installing a fixture between two projected strips, which are projected in width larger than the diameter of the head of the fixture and form deeper than the height of the head, to a fixing surface on the upper end. CONSTITUTION: In building panels A, which comprise a synthetic resin material having male and female connection structure on both upper and lower ends, two strips of projected parts, which are projected in width larger than the diameter of the head β1 of a fixture βand formed deeper than the height of the head β, are formed on a fixing surface 15 on the upper end. Prior to fixing the building panels A with a skeleton α, the fixture β is installed to a fixing hole between two projected strips. Then, the projected strips hinders the installation of the fixture β so that it may not be installed up to the fixing surface 15 so that a clearance may be left over. This construction makes it possible to move the building panels A thus constructed on both ways and absorb thermal expansion.  It is, therefore, possible to prevent a decorated surface from being strained as a result of thermal deformation of the panels A and protects the separation from the skeleton α.

Abstract: PROBLEM TO BE SOLVED: To provide a pachinko machine which is not disadvantageous to the side of game shop while improving the probability of the execution of a special game and allowing players to enjoy. SOLUTION: CPU opens a large prize winning port (S303), and when a specific ball detecting signal (V signal) from a V switches (S306: YES), closes the big prize winning port (S309) after setting the continuing flag F3 to be 1 (S307). However, since CPU opens the port again when the number of opening time does not amount to a regulated number, the number of prize balls to be paid out by entering the port each special game is reduced. Thus, in spite of making the probability of winning about 1/100, which is remarkably higher than the winning probability of a conventional pachinko machine, the number of prize balls is never increased too much. Thus, players can enjoy and disadvantage to the side of game shop is never generated by improving the executing probability of the special game.
