Title: Camp-on system
Inventor: IWASAKI TAKESHI
IPC: H04M3/48
Filed: 1988-12-20
Abstract: PURPOSE:To connect a calling subscriber and a called subscriber and to attain the call between the calling subscriber and the called subscriber when the called subscriber returns by providing a storing means for subscriber information about both the called and calling subscribers, etc., and requesting a camp-on service even when no response is obtained since the the called subscriber is out, etc. CONSTITUTION:When a subscriber 1 calls a subscriber 2 and executes a hooking operation in order to request the camp-on service in the case of the absence of the subscriber 2, a central processing unit 11 detects this and connects the subscriber 1 and a call originating register 8. Next, the subscriber 1 dials a special number, the register 8 transfers this number to the unit 11, and the unit 11 analyzes the transferred number. When it is decided that the number indicates the camp-on service according to the analyzed result, the unit 11 combines the information about the subscriber 1 and the information about the subscriber 2 stored in the register 8 and writes the combined information in a memory 12. Further, when the subscriber 2 returns to his/her seat, executes an off-hook operation, and after that executes an on-hook operation, the unit 11 compares the storage contents of the memory 12 with the subscriber information about the subscriber 2 and camp-on connects the subscribers 1 and 2 when the compared result is coincidence. Thus, the call can be easily attained without necessitating the calling subscriber to the call the called subscriber again several times.

Filed: 1988-12-21
Abstract: PURPOSE:To shorten test time by performing the counting of a coincidence signal at a time even when a one-bit error exists, and judging a test as good when a prescribed count value can be obtained within prescribed time. CONSTITUTION:When test data is transmitted from a test data generation circuit 5, a data coincidence counter circuit 11 counts a data coincidence signal outputted from a comparator 8, and outputs a signal to a test result circuit 13 when coincidence between a number set in advance can be obtained successively, and resets the count value to zero when noncoincidence in data occurs on the middle way of counting, and after that, starts the counting of the number of coincidence bits again. The test result circuit 13 outputs the signal setting the test result as good by the signal from the data coincidence number counter circuit 11. When the test result is not judged as good before the counting by a time-out counter circuit 12 is completed, a test completion circuit 14 outputs a test completion signal, and judges the test result as defective. In such a way, it is possible to shorten the test time for a line even with inferior line quality.

Title: Microwave oven
Inventor: KODA TETSUYA
IPC: F24C7/02
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To uniformize the electric power density distribution by a microwave in a heating cabinet, and uniformize the temperature distribution of preparations by chaotically reflecting a microwave generated by a magnetron by a wall surface of the heating cabinet, and preventing a reflecting locus of the microwave from tracing the same route. SOLUTION: A magnetron 1 to generate a microwave is controlled by a current-carrying control means 3. The current-carrying control means 3 generates high frequency high voltage supplied to the magnetron 1. The microwave generated by the magnetron 1 is guided up to a heating cabinet 4 by a waveguide 2. The microwave is reflected by a cross-sectional elliptic wall surface 4a of the heating cabinet 4, and is uniformly distributed in the heating cabinet 4. Since the wall surface 4a of the heating magazine 4 is formed in an elliptic shape, the microwave is chaotically actuated, and collides with the wall surface 4a of the heating cabinet 4, and covers the whole area while repeating reflection. Therefore, a heating object 5 set in a bottom part of the heating magazine 4 is uniformly heated.

Title: Manufacture of semiconductor device
Inventor: YAMAMOTO HIROAKI
IPC: H01L21/205
Filed: 1989-12-15
Abstract: PURPOSE:To form a nondefective layer also under the interface between a substrate and an epitaxial layer, by holding a semiconductor silicon substrate in a first specified temperature range, increasing the temperature at a specified rate, from the first temperature range to a second specified temperature range, and holding the substrate for a period shorter than or equal to a specified interval. CONSTITUTION:A semiconductor silicon substrate 1 is held for 8 hours or less in a first temperature range from 450 deg.C to 600 deg.C. The temperature is increased from the first temperature range to the second temperature range from 750 deg.C to 900 deg.C, at a rate of 5 deg.C/min. The substrate is held for 4 hours or less in the second temperature range. An epitaxial layer 2 is formed on the surface of the semiconductor silicon substrate 1 after the holding in the second temperature range is finished. That is, by setting the second temperature range to be from 750 deg.C to 900 deg.C, the size of a defect is restricted within a radius capable of dissolution and outward diffusion in the temperature range of a subsequent epitaxial process. Hence the dissolution and outward diffusion of defects are progressed. Thereby a nondefective layer 4 of about 10mum in thickness is formed under the interface between the substrate surface and the epitaxial layer.
