Title: Remote control unit
Inventor: KASHIMA KOTARO
IPC: H04B1/04
Filed: 1994-03-15
Abstract: PURPOSE:To provide a means which notifies that a portable audio equipment body is defective by a wireless remote controller. CONSTITUTION:When a remote control control part A is detached from the equipment main body part B, a remote controller attachment/detachment detection switch 15 turns OFF and then a receiving circuit is placed in operation through a main body control part 11 and a transistor(TR) 13 to enter a reception wait state. A sent series signal including a remote control operation command code is generated by a remote control part 3 with an operation command switch 1 and sent with an electromagnetic wave, and the signal is received by a equipment main body part B and decoded by the main body control part 11, thereby controlling a reproducing device 14 according to the decoding result. For example, if the remote control part A is put too far away to receive a specific code for transmission arrival confirmation 10 the sent series signal, it is judged that the equipment main body part B can not be controlled remotely and an alarm signal is sent from the main body control part 11 to an earphone 7 to give notice of that. Once the remote control part A is attached to the equipment main body part B, the switch 15 turns ON and the reception wait state is reset.

Title: Current source bias circuit
Inventor: MIZOGUCHI SATOSHI
IPC: H03F3/343
Filed: 1988-02-29
Abstract: PURPOSE:To relieve the load of a bias circuit in OFF-state by connecting a constant voltage circuit terminal prepared to one end of a drain-source electrode of a MOS field effect transistor(TR), acting other end like a bias voltage output terminal and using the gate electrode as an ON/OFF control terminal of a bias voltage output. CONSTITUTION:With the source-drain impedance of MOS field effect MOS TRs 8a-8c decreased by a potential at control terminals 9a-9c, output terminals VoutA-C are connected to a voltage source 7 at a low impedance state and they are made to an equal potential, the TRs are turned on. With the source-drain impedance of the MOS field effect TRs 8a-8c increased (infinite) by the potential at the control terminals conversely, the output terminals VoutA-C are substantially disconnected from the constant voltage source 7 and the TRs are turned off. Thus, the bias power supply circuit with ON/OFF function without causing excess current in the OFF-state especially is obtained.

Title: Manufacure of lithium-aluminum alloy electrode for battery use
Inventor: MASUDA YOSHITOMO
IPC: H01M4/1395
Filed: 1987-02-26
Abstract: PURPOSE:To prevent defective part such as cracks from being generated on the periphery of an electrode by pressing lithium of an aluminum plate so as to specify a ratio of a lithium pressed area to an area of an aluminum plate's pressed side. CONSTITUTION:While a peripheral part of an aluminum plate's pressed side is exposed, lithium is pressed on a lithium plate so that a ratio of a lithium pressed area SLi to an area SAQ of an aluminum plate's pressed side is expressed in SLi/SAQ<=0.99. Thus, the peripheral part of the aluminum plate's pressed side is not alloyed with lithium and so aluminum remains as ground metal. Otherwise even if lithium permeates to alloy to the peripheral part, a degree of the alloying on this part is small compared with a part pressed by lithium. Therefore, the peripheral part is prevented form being fragile and breakable, so that physical strength on the peripheral part can be maintained.

IPC: G10G3/04
Filed: 1988-02-29
Abstract: PURPOSE:To accurately identify the interval of each segment, by further looking at the intervale of a segment again when the difference between the adjacent intervales in the scale of a melody determined in an identified intervale is a semitone. CONSTITUTION:A CPU 1 judges whether an identified intervale to be processed is a semitone in the difference between the intervales adjacent to each other on the intervale of a determined key. As the result of the judgement, when said interval is a semitone, the CPU 1 totalizes the pitch data present between the identified interval of a segment and the intervale different by a semitone on the scale of the determined melody. Subsequently, the CPU 1 calculates whether the pitch data larger than the intermediate pitch data of said semitone are many or the pitch data smaller than said intermediate pitch data are many and identifies the intervale on the absolute axis near to many pitch data as the intervale of the segment. By this method, even in such a case that scale difference is a semitone, an identification mistake can be removed.
