Title: Signal tone detection system
Inventor: KATAGIRI KUNIKAZU
IPC: H04M11/00
Filed: 1990-11-30
Abstract: PURPOSE:To prevent malfunction of an automatic notice device by shifting a phase of an input signal tone, detecting a level difference between an original signal and a signal tone after phase shift, discriminating the level difference by a comparator so as to detect the presence of a voice signal or the like. CONSTITUTION:An inputted busy tone is delayed for the phase by 180 deg. at a phase shift circuit 1 and a signal (a) after phase shift and an original signal are inputted to a differential amplifier circuit 2 to detect a level difference (b) between both the signals. The signal (b) is subjected to effective value processing (c) by an effective value processing circuit 3 and compared with a threshold level set optionally by a processing section 4 of a next stage to binarize the signal (d). The signal (d) is used to control an output signal (e) from a signal tone detection section 5 thereby detecting a busy tone. Thus, mis-detection of the signal tone detection section 5 due to voice signal or the like is prevented.

Title: Surface observation optical system
Inventor: HAYASHI NAOHISA
IPC: G01M11/02
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To provide a surface observation optical system in which light from a non-observation object part of a surface to be inspected is prevented from entering the observation surface, and the brightness contrast of an image on the surface to be inspected formed on the observation surface can be improved. SOLUTION: A diaphragm 4 is disposed between a light source and a surface 1 to be inspected, and the irradiation range of illuminating light 30a is limited in such a manner that illuminating light is not applied to the part (non- observation object part 10b) outside the observation object part 10a of the surface 1. Thus, reflected light from the non-observation object part 10b does not exist, so that reflected light from the non-observation object part 10b is prevented from entering an image 30a. Thus, as compared with the case of disposing the diaphragm 4, the brightness contrast of the image 20a can be improved.

Title: Method and apparatus for initializing data-recording medium
Inventor: KAWAHARA KATSUMI
IPC: G11B7/0055
Filed: 1993-12-24
Abstract: PURPOSE:To eliminate the need for attaching of labels or the like by coating a central part of a disc with a mask of a predetermined cut information and crystallizing a recording film. CONSTITUTION:When the recording film of a disc substrate 3 is exposed and crystallized by the flash light of a plurality of Xenon lamps 2, a central part of the disc substrate 3 is covered with a mask 4 thereby to shut the light. Moreover, data related to the disc substrate 3 are preliminarily cut and crystallized on the mask 4. As a result, cut characters emerge because of a difference of reflectances between the cut characters and a part of the disc substrate 3 covered with the mask 4, making it unnecessary to attach labels or the like. The crystallization is carried out by the output of the Xenon lamps 2, so that an initial crystallization time is shortened. The cut data in the mask 4 are preferably lot No. of the disc, trade mark, manufacture's name, etc.

Title: Channel calculation method/system in grid-type communication network system
Inventor: KIN SEIGEN
IPC: H04L45/24
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To provide a method and a system for reducing the calculation quantity of channel judgment executed for judging the connection/disconnection of a communication network in a grid-type communication network management system. SOLUTION: When a link breaks down in the channel calculation method of a grid-type communication network management system (3b), whether a bypass route exists between both nodes in the link or not is judged (3c). If the bypass route exists, a route which can substitute the link that breaks down exists. Thus, only the state of the link is set to a fault state. If the bypass route does not exist, the communication network is judged to have been separated (3d), and it is processed (3f) as a recognition impossible state which cannot be managed with a management node.

Filed: 1999-11-19
Abstract: PROBLEM TO BE SOLVED: To provide a malfunction preventing method and circuit by which noise can be masked by using the frequency of a clock signal, which is higher than the frequency of an input signal. SOLUTION: A buffer 1 detects the logic level of an input signal 101 and outputs a signal 102 which is waveform-shaped. A first edge detection circuit 2 holds the logic level outputted when the change point of the signal 102 outputted from the buffer 1 is detected. A second edge detection circuit 3 starts counting when the first edge detection circuit 2 detects the change point and outputs a reset signal 105 when it counts the number (m) of the change points of a clock signal 103 whose frequency is n-times as much as the input signal 101, which is previously set. Thus, noise mixed at the start time of the input signal 101 is masked by the setting and the resetting of the first edge detection circuit 2 and the second edge detection circuit 3 by the signals outputted from them.

Abstract: PURPOSE:To contrive improvements in moldability and productivity by high-cycle molding by obtaining a mold temperature necessary for the molding and a mold temperature necessary for cooling, by a method wherein high-temperature gas is fed within a cavity prior to filling of molten resin into the cavity. CONSTITUTION:An injection controller 22 is operated under a mold breaking state and a temperature control medium through a mold temperature control machine 11 is circulated within temperature control passages 9, 13. With this construction, a stationary side mold 2 and movable side mold 3 are kept cooling always at a temperature necessary for cooling a molded product In the case where the title method is entered a molding action under this state, high-temperature gas from a high-temperature gas generating device 21 is fed within a cavity by blowing against the cavity through a high-temperature gas passage 15 on an entering side in the movable side mold 3. Then when a mold 1 is clamped while the high-temperature gas is being sent over the cavity 4, the high-temperature gas is fed directly to only the surface of the cavity 4 by blowing against the surface, the surface is heated and becomes an appropriate temperature for molding of molten resin. When the molding is completed, since the mold 1 is restored immediately to the temperature of the temperature of the temperature control medium, the molded product also is cooled rapidly and the mold 1 is broken, through which the molded products can be taken out.
