Title: Positioning method in electron beam exposure
Inventor: FUKUDA HISASHI
IPC: H01L21/027
Filed: 1982-01-28
Abstract: PURPOSE:To prevent the decrease of a mark detection accuracy even when processes advance by a method wherein a P-N junction is previously formed on a wafer as the mark, and the electromotive force generated at the P-N junction part by an electron beam irradiation is detected. CONSTITUTION:P-N junctions 2 are formed at fixed surface parts of the wafer 1. This wafer 1 is set up in a jig 10, and then the surface of the wafer 1 is scanned and irradiated by the electron beam probe 15 from the aperture of an external case 11. Then, the pair of electrons and holes is generated at the junction 2 at the time the probe 15 has scanned the junction, and flows into the probe 13. The P-N junction detection wave form signal is obtained by amplifying the electromotive force current in an amplifier 16, and the differentiation treatment changes this signal into the differentiation signal, and accordingly the central position of the P-N junction i.e. mark is calculated. By this method, even when processes further advance resulting in the formation of multilayer films, the mark can be detected without decreasing the detection accuracy.

Title: Dielectric filter
Inventor: MORIZAKI TADAHIRO
IPC: H01P1/212
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To suppress spurious radiation by forming dielectric resonators in rings whose outer diameters are equal to each other and whose inner diameters differ. SOLUTION: A 1st dielectric resonator 2 and a 3rd dielectric resonator 4 at both ends among the 1st to 3rd dielectric resonators 2-4 are formed in rings whose inner diameter differ. Furthermore, the 2nd dielectric resonator 3 is formed into a disk, and the outer diameter of the 1st to 3rd dielectric resonators 2-4 is formed identically. In this case, each of the dielectric resonators 2-4 is resonated in electromagnetic coupling only at a desired frequency (fundamental wave mode) and not resonated because no electromagnetic coupling is caused at other harmonic mode frequencies. Thus, only a signal of a desired frequency component being the fundamental mode passes and is outputted at an output of the dielectric filter and only a few frequency components in other harmonic modes are outputted.

IPC: H04M3/00
Filed: 1995-01-31
Abstract: PURPOSE: To simply check a connection state between switchboards without requiring manual operation by collecting path information by communication between the switchboards. CONSTITUTION: This communication system has a communication style applied to plural switchboards 1 to 4 between two subscribers A, B. The switchboard 1 receiving a communication path information collection request signal collects path information in its own switchboard 1 based on program data stored in its own switchboard. When a path to be collected is connected to another switchboard 2, the switchboard 1 transmits an information collection start request signal to the switchboard 2 and collects the communication path information of the other switchboard 2 by communication between the switchboards 1, 2. After receiving an information collection start checking signal, the switchboard 1 transmits an information collection request signal to request the collection of communication path information in the switchboards 3.  After receiving an information collection result signal, the switchboard 1 refers to information indicating whether collected information is connected to other applied switchboards or not, and when the connection exists, transmits the information collection request signal again to collect the communication path information of the succeeding switchboard 4.

Title: Iron core for induction heating
Inventor: MATSUSHITA YASUHIRO
IPC: H01F27/24
Filed: 1980-02-08
Abstract: PURPOSE:To decrease greatly the iron loss caused by leakage flux, by bundling the magnetic metal wires with insulating cover, laminating them into a desired shape and adhering them to the outside of an iron core of layered electromagnetic steel plate. CONSTITUTION:Unit metal wire (magnetic body) 8 is insulated by cover 9 and bundled to form a laminated iron core 10, using a frame. The iron core 10 is adhered to the outside of an iron core 2 of layered electromagnetic steel plate. With such an arragement, path for the overcurrent caused by leakage flux in the lateral axis is narrowed so that the absolute value for the overcurrent decreases. This in turn decreases the iron loss, leading to the more effective performance of induction heating. The iron core 10 takes effect even if it is quite thin. The thicker the core is, the less the iron loss. The thickness depends on economy.
