Title: Musical sound signal synthesizer
Inventor: TAKEUCHI KAZUFUMI
IPC: G10H7/12
Filed: 1999-12-16
Abstract: PROBLEM TO BE SOLVED: To synthesize complex musical sound waveform signals including a large amount of harmonic overtone employing a simple constitution. SOLUTION: A phase information generator 11 supplies phase information 'x', which is made up with sawtooth shaped waves that vary with the frequencies corresponding to the pitches of musical sound to be generated, to a sine wave table 13 through a computer 12 and reads output waveform information 'y' from the table 13. The information 'y' is fed back to the computer 12 through an absolute value converter 14, a low pass filter 15 and a gain adjuster 16. Thus, the information 'y' outputted from the table 13 is nonlinearly converted, fed back to the information 'x' and the information 'x' is varied in a complex manner and as a result, the information 'y' representing complex waveforms is outputted from the table 13.

Title: Cleaning solution for semiconductor substrate and method for washing the substrate
Inventor: MATSUO CHIZUKO
IPC: C11D7/08
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To effectively remove both metallic impurities and fine particles attaching to the surface of a semiconductor substrate in a single tub. SOLUTION: Using cleaning solution 15 which includes 0.001-0.1wt.% of organic acid and 0.005-0.25wt.% of hydrolytic acid and has a pH 2-4, a semiconductor substrate 11 is cleaned. When the contaminated substrate 11 is dipped in the cleaning solution, a natural oxide film 12 formed on the surface of the substrate is removed by hydrofluoric acid, and fine particles 13 on the film and metallic impurities on and in the film move (b) into the washings (b). Since the cleaning solution is an acidic solution of pH 2-4 including organic acid, the particles are charged negative just as the surface of the substrate and the metallic impurity ions in the cleaning solution become negative complex ions due to a complexing effect of the organic acid. As a result, the surface potentials of the fine particles and the metallic impurities become negative as that of the substrate and therefore are prevented from attaching or reattaching to the substrate 11 (c).

Title: Timing calibration method, timing-calibrating apparatus, and ic-testing device with timing-calibrating apparatus
Inventor: NAGAI HIROYUKI
IPC: G01R31/28
Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To absorb the linearity error of a phase-setting circuit, and set proper delay time where the error is removed by utilizing the setting state of a setting value, and by adjusting the delay time of the phase correction circuit of each channel so that in-phase state is achieved at the terminal of a signal transmission line. SOLUTION: A first calibration operation control means 132 inputs a delay setting value being used as a standard to a phase-setting circuit 114A of each channel, and sets each delay time of the phase-setting circuit 114A. Since the actual delay time of the phase-setting circuit 114A includes a linearity error, the phase of a signal being supplied to each terminal of an IC socket SK is not aligned to be the same phase in this state, thus connecting another measuring equipment such as an oscilloscope to each terminal of the IC socket SK, and adjusting the delay time of a phase correction circuit 114B so that the phase of the signal becomes the same at the terminal part of each IC socket SK. More specifically, a setting value is inputted to the phase correction circuit 114B from an input means 131, and the delay time of the phase correction circuit 114B is adjusted.

Title: Control valve system
Inventor: RUSSELL NEIL E
IPC: F15B20/00
Filed: 1997-12-16
Abstract: PROBLEM TO BE SOLVED: To actuate a control valve system completely by the air pressure and to omit the electrical monitoring of a relative controller by moving the system to its de-energizing position from its lock-out position when one of plural valves moves to its de-energizing position from its energizing position. SOLUTION: When a control valve system is moved to its de-energizing position from its lock-out position, a pressure fluid is supplied to a reset path 96. The pressure fluid of the path 96 opens a check valve 98 and fills a reservoir 24 and a chamber 54. A throttle 56 limits the amount of fluid that flows into a discharge path 18. When the reservoir 24 and the chamber 54 are once filled with the pressure fluid, the inside fluid of the chamber 54 acts on a piston 110 to move up a valve member 102 and to fit the piston 108 into a housing 12. Thus, a fluid path 40 is linked again to a path 52 and the system 10 is set at its de-energizing position.

Title: Deprotection of carboxyl group and hydroxy group protected with alkynylmethyl group
Inventor: KUSUMOTO SHOICHI
IPC: C07B51/00
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To efficiently deprotect carboxyl group and hydroxy group protected with an alkynylmethyl group by bonding the carboxy group and the hydroxy group with the alkynylmethyl group, by allowing a strong acid to act on the protected product in the presence of a metal or a metal complex to isolate the carboxy group and the hydroxy group. SOLUTION: For example, in the reaction formula (R is H, an alkyl, phenyl or the like; R1 and R2 are each an alkyl or the like), when an alkynylmethyl alcohol of structure 1 is reacted with a carboxylic acid 2a or an alcohol 2b to provide a corresponding alkynylmethyl derivative 3a or 3b, respectively, each of the carboxy group and hydroxy group is protected. When a strong acid such as trifluoroacetic acid(TFA) is allowed to act on the alkynylmethyl derivative 3a or 3b in the presence of a metal or a metal complex (e.g. cobalt carbonyl complex), the alkynylmethyl derivative 3a or 3b is deprotected to regenerate the original carboxylic acid 2a or alcohol 2b.

Title: Buffer control circuit
Inventor: OIKAWA MASAHIKO
IPC: G06F13/38
Filed: 1999-12-24
Abstract: PROBLEM TO BE SOLVED: To reduce the memory capacity of a buffer memory. SOLUTION: A differential calculating circuit 22 acquires the held data amount of a correspondent buffer memory 4 at intervals of a fixed time, finds a differential from the last data amount and provides a bit rate during a relevant period. According to this bit rate, a priority change circuit 24 sets the higher priority to the buffer memory 4 of the higher bit rate. On the basis of this set priority, an arbitration circuit 18 selects the buffer memory 4. Therefore, the high priority is dynamically set to the buffer memory 4 to which data is frequently inputted at the time of operation, the wait time of such a buffer memory is shortened and the held data can be frequently outputted. As a result, even when memory capacity is small, overflow does not occur and the memory capacity of the buffer memory 4 can be reduced.
