Title: Information processor
Inventor: HIGAKI NOBUO
IPC: G06F15/78
Filed: 1992-09-16
Abstract: PURPOSE:To provide the information processor which can evade a conflict on a bus and can access to data not through a decoder part and can be im proved in performance and can be increased in clock frequency by reducing the load on a bus. CONSTITUTION:A bus switch control part 117 performs ON/OFF control over 1st and 2nd bus switches 118 and 119. When the 1st bus switch 118 is ON, a data path part 103 can access to both an internal ROM 104 and an internal RAM 105. In this case, they can not be accessed at the same time. When the 1st bus switch 118 is OFF, the data path part 103 can access to the internal RAM 105 and the decoder part 101 can fetch an instruction code from the internal ROM 104. Further, those processes can be performed at the same time and the 2nd bus switch 119 is the same.

Title: Preparation of compound thin film by electro deposition and its compound thin film
Inventor: HARA SHIGETA
IPC: C25D3/56
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To provide a prepn. method of a compd. thin film forming a compd. expressed as AB by an electro deposition, which operates effectively, more juicily and at ambient temp. without necessitating a special operation such as a vacuum operation, and contrives improvement of productivity. SOLUTION: An AB thin film is formed on a substrate by operating an electrodeposition of an electrolytic solution contg. A and B at a potential, which is lower than an electro deposition potential of B and higher than an electrodeposition potential of A. By this operation, part of a simple substance A is absent. And a rate of electrodeposition of B is controlled (to a particularly slow rate) by controlling a concn. of B (to a low concn. particularly low) in such a concn. range that the electrodeposition of B is a diffusion controlled reaction on the basis satisfying the above described electrodeposition condition. Beside, such a condition that a formation rate of the AB compd. by combining A to B becomes faster than a deposition rate of a single substrate B is selected by making concn. of A high enough. By this operation, a single substrate B is also absent.  Accordingly, an AB compd. thin film contg. neither single substrates of A nor B can be prepared.

Title: Semiconductor negative resistance element
Inventor: MUTO SHUNICHI
IPC: H01L29/68
Filed: 1986-10-20
Abstract: PURPOSE:To form a resistance element which has large tunneling current and a large P/V ratio by composing a resonance tunneling barrier of a GaAs barrier layer and an InAs well layer. CONSTITUTION:A resonance tunneling barrier composed of GaAs barrier layers (e.g., nondoped GaAs barrier layers 3, 5) between which an InAs well layer (e.g., nondoped InAs well layer 4) is interposed. Semiconductor layers can be extremely easily grown by a molecular beam epitaxially growing method. Since the effective mass of electrons is extremely small in the layer 3, the tunneling probability in the resonance tunneling barrier becomes large, and a large tunneling current can flow. Further, a scattering probability becomes small, the V of a P/V ratio can become small, i.e., the P/V ratio can become large. Accordingly, when a semiconductor negative resistance element provided with the barrier is used as an oscillator, a large oscillation output can be obtained. When it is used as a logic circuit, a large logic amplitude can be obtained.
