Title: Synthesis of single crystalline diamond with hydrogenated amorphous carbon
Inventor: YOSHIDA HIROSHI
IPC: C01B31/06
Filed: 1995-07-02
Abstract: PROBLEM TO BE SOLVED: To synthesize single crystal diamond excellent in crystallinity. SOLUTION: Hydrogenated amorphous carbon mainly having a sp<3> structure is prepared by hydrogenating carbon, decomposing the hydrogenated carbon gas and subsequently quenching the decomposition product on a substrate, or spattering graphite with hydrogen atoms. The hydrogenated amorphous carbon is irradiated with X-rays in radiations to excite the 1s shell electrons of the carbon and convert the carbon atoms into the excited state of 2 ions by Auger effect, thereby producing atomic holes and interstitial atom pairs. The excited carbon atoms are annealed at a sufficiently lower temperature than the melting point to rearrange the carbon atoms into the arrangement of the diamond only by the transfer energy of the interstitial atoms.  The synthetic method can be applied also to the growth of a diamond single crystal thin film on a single crystal substrate, e.g. the semiconductor of the III-V group element compound or the II-VI group element compound such as amorphous carbon, silicon or GaAs. Thus, synthetic diamond or diamond thin films suitable for high temperature semiconductor devices, UV light laser diodes, transparent single crystal- protecting films, etc., are obtained by the method.

Title: Branch predicting method and data processor
Inventor: KURATA KAZUJI
IPC: G06F9/38
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To predict whether or not a branch is established with a small hardware scale by predicting whether or not a branch is generated in the past according to the result of the latest condition branch and whether or not branch prediction of past several times is hit. SOLUTION: It is predicted whether or not a branch is generated in the past by holding or inverting the actual result of the latest conditional branch according to an acceptance or rejection history pattern showing whether or not a branch is recorded and whether or not branch instructions of past several times are hit. When patterns of branch prediction acceptance or rejection information are 1110, 1101, 1011, and 0111, the prediction is done by the inversion of the branch result of the current time (t) right before. For example, when the last branch result is 1 (branch), nonbranching is predicted to set branch prediction information to O and when the last branch result is O (nonbranching), branching is predicted to set the branch prediction information to 1.  At this time, acceptance or rejection is EXCLUSIVE-NOR between the branch prediction information at time t-1 and branch prediction result at time (t) and made evident at the time (t). When the pattern of the branch prediction acceptance or failure information is 1111, the prediction is performed by holding the last branch result.

IPC: H04B1/40
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To provide a function that sends an electric signal to be converted into a voice signal easily heard without being affected by surrounding noise by eliminating signals other than voice signals from an electric signal sent from a vibration detection section. SOLUTION: In the case of using an ear transmitter-receiver, an ear section 3 is inserted to an external auditory canal from an external auditory canal press contact section 30. In the case of inserting it, the external auditory anal press contact section 30 is deformed so that its circumferential ridge is close to the inside in the radial direction and the circumferential ridge of the external auditory canal press contact section 30 is in elastic contact with the external auditory canal to shut the external auditory canal from the inside of the external auditory canal. When an electroacoustic signal is given to the ear transmitter-receiver, the electroacoustic signal is amplified by an earphone driver 20 and is sent to an earphone speaker 14 via a wiring section 5 and transduced into a sound.  In this case, since the circumferential ridge of the external auditory canal press contact section 30 is in elastic contact with the external auditory canal to shut sound between the external auditory canal and the inside of the external auditory canal, external noise is hardly received.
