Title: High-frequency high-output transistor
Inventor: KAGAWA KAZUHISA
IPC: H01L21/60
Filed: 1989-11-02
Abstract: PURPOSE:To improve the accuracy in assembling by attaching a mark to the position where a wire is bonded to an inner lead. CONSTITUTION:A rectangular mark 4 is attached to the place, where a wire 2 is bonded, at the surface of the inner lead 1 of a transistor package 3, and the wire 2 is bonded so that the bonding part may be stored inside it. That is, since the position to bond the wire 2 is made clear at the surface of the inner lead 1, the wire 2 can be bonded accurately in assembling. Hereby, the accuracy in assembling can be improved, and the I/O impedance of respective transistors becomes equal, so high frequency properties can be stabilized.

Title: Zirconia-base refractory and its production
Inventor: IIZUKA YOSHIHARU
IPC: C04B35/66
Filed: 1995-11-06
Abstract: PROBLEM TO BE SOLVED: To obtain a refractory excellent in durability in use by correcting such defects of a zirconia-contg. refractory as the wettability with slag, susceptibility to slag corrosion and low resistance to spalling due to its large thermal expansion. SOLUTION: This refractory contains a zirconia-base composite material contg. at least ZrO2 and ZrC as the mineral composition. The refractory contg. a zirconia-base composite material contg. ZrC is hardly wetted with slag in the operational aspect and exhibits corrosion resistance. Further, the refractory is low in thermal expansion and excellent in spalling resistance. In the case of the carbon-contg. refractory, since the oxidation of ZrC takes place in the lower temp. range than the carbon material such as graphite, an effect as an agent for preventing the oxidation of carbon is expected due to its oxygen capturing action. In the case of the refractory not contg. carbon, ZrC is converted to ZrO2 in the firing process of the refractory, the void of the material is filled up, the structure is densified, and the corrosion resistance is improved.

Title: Musical sound producing device
Inventor: TOMITA HIROSHI
IPC: G10H1/18
Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To provide the musical sound producing device which suitably plays in concert by connecting plural equipments. SOLUTION: When the decision of SA2 is YES and another equipment is connected to an input terminal, the CH number (transmission channel number) of the connected opposite terminal is registered (SA3) and then retrieval is performed to check whether or not a sound source has a free CH (free sounding channel) (SA4). When there is the free sounding channel, the channel having the smallest number is set for the sound production of the responding opposite equipment (SA5) and assigned to a sounding channel. Then the set CH number is sent to the opposite equipment (SA7) and then a next process is started. Therefore, when other new equipments are connected to the input terminal one after another, different sounding channels are assigned to the respective equipments without assigning the same channel repeatedly as long as free sounding channels are left.

Title: High speed semiconductor switching device
Inventor: KAMEI YOSHIO
IPC: H01L29/74
Filed: 1989-11-07
Abstract: PURPOSE:To prevent power loss of a high speed turn-on element from being increased for prevention of the destruction of the high speed turn-on element by setting internal capacitance of anti-parallel connection diodes to be smaller than that of the high speed turn-on element. CONSTITUTION:A sub L-C resonator circuit is formed at a high speed turn-on element 5 and an anti-parallel diode 6. Herein, internal capacitance of the diode 6 is set to be smaller than that of the high speed turn-on element 5. As the internal capacitance of the anti-parallel diode 6 is reduced, its discharge current is also reduced. Thus, a current superimposed from the anti-parallel diode onto the high speed turn-on element at the early time of the turning-on of the high speed turn-on element 5, is reduced and hence power loss through the high speed turn-on element is reduced.
