Abstract:
Pin head mounting members are rotatably mounted on a horizontal spindle above a table which horizontally supports a holding, plate holding chip type electronic components. The spindle is vertically movable by a vertical cylinder. Each pin head mounting member is shaped as a rectangular sleeve. A mounting surface is formed on each side portion of the pin head mounting member. A pin head each having a number of press pin is detachably mounted on each of the mounting surfaces A locking pin is provided on an upper end portion of the spindle for locking the pin head mounting members every 90.degree.. Thus, it is possible to efficiently replace press pins in response to a type change of chip type electronic components, as well as to quickly exchange a broken press pin.
Abstract:
An electronic musical instrument comprises a keyboard, a tone signal forming circuit to produce musical tone signals corresponding to keys being depressed on the keyboard, a memory to store musical performance data, a keyboard display device to visually instruct a pupil or trainee as to which keys are to be depressed on the keyboard in accordance with the performance data read out of the memory so that the pupil or trainee may effect a musical performance on the keyboard while following key indications, and an automatic musical performance device to effect an automatic musical performance of different type from the musical performance effected on the keyboard. The pupil or trainee may selectively effect the musical performance on the keyboard with or as the accompaniment by or for the automatic musical performance. Preferably the pupil or trainee effects a melody or chord performance on the keyboard with the accompaniment of an automatic chord performance and/or an automatic rhythm performance, or an automatic melody performance and/or an automatic rhythm performance.
Abstract:
Provided is a process for producing bleached pulp, including subjecting unbleached pulp, which is obtained by cooking a lignocellulose substance, to alkali-oxygen bleaching treatment and then subjecting the alkali-oxygen bleached pulp to chlorine-free bleaching treatment including chlorine dioxide treatment, wherein in at least one chlorine dioxide treatment stage in which the chlorine dioxide treatment is performed, monopersulfuric acid is used in combination. The amount of chlorine dioxide to be used is reduced and the color reversion resistance of the bleached pulp is improved by this process.
Abstract:
A sensorless-brushless motor control device comprises an inverter, an inverter drive circuit that drives the inverter and a current control part that controls the inverter drive circuit according to a current command from a superior control part and includes a first order lag compensating part. The device is characterized by further comprising a control mode changeover judging part that judges changeover of a control gain of the current control part after startup of the sensorless-brushless motor in response to a motor revolution sensing signal from the inverter drive circuit and a control mode changeover part that changes over the control gain of the current control part in response to an output of the control mode changeover judging part.
Abstract:
The invention provides a method for producing a peroxymonosulfuric acid solution with high stability, including the steps of mixing 35 mass % or more of hydrogen peroxide and 70 mass % or more of sulfuric acid to react them, cooling the reaction solution to 80° C. or lower within five minutes after initiation of the mixing step, and diluting the reaction solution with water four times or more as much as the reaction solution by mass.
Abstract:
Polyphenylene ether particles which contain fine powder in a small amount and are easy to handle at the time of molding, are obtained. A method for precipitating polyphenylene ether, which comprises adding a non-solvent for polyphenylene ether to a solution of polyphenylene ether in a good solvent for polyphenylene ether to precipitate polyphenylene ether continuously in a stirring vessel with a reciprocating stirrer, wherein the polyphenylene ether solution is dropped outside the working range of a stirring blade.
Abstract:
In a multiplex communication system for transmitting and receiving data between a master station and a plurality of slave stations, the master station comprises a discriminator for collating an important switch information data transmitted from each slave station for reliability improvement. That is, two or more bit switch data transmitted by the slave station are compared with those stored in the master station and determined to be correct on the basis of a perfect bit level match or a bit level majority decision. Further, it is also possible to compare first data transmitted by the slave station with second data transmitted again by the slave station immediately after the first data transmission. Furthermore, it is preferable to change the access sequence from the master station to the slave stations according to power supply modes determined by ignition key switch positions for providing a higher response speed.
Abstract:
In a wave form signal generating apparatus designed to memorize a desired wave form in the form of a floating point representation for generating a wave form signal based on the memorized wave form, a mantissa and an exponent of a sampling data of the desired wave form are memorized in a predetermined number of digits as a compressed information, and a digit number of the memorized exponent allotted in the predetermined number of digits are further momorized. The memorized exponent is extracted on a basis of the memorized digit number so that the wave form signal is reproduced on a basis of the extracted exponent and the mantissa allotted in the remaining portion of the predetermined number of digits.
Abstract:
A system and method for automatically controlling a vehicle speed to a desired cruise speed are disclosed in which a vehicle speed sensor which output an analog quantity corresponding to a current vehicle speed is provided, a vehicle speed determining circuit which derives the current vehicle speed on the basis of the analog quantity derived from the vehicle speed sensor and determines whether the derived current vehicle speed is below a predetermined speed above which the cruise speed control run is appropriate is furthermore provided independently of a control unit of the system. When the vehicle speed determining circuit outputs a determination signal indicating that the current vehicle speed is below the predetermined speed and the control unit outputs a predetermined control command signal, a power supply line connected to a throttle valve actuator is, at first, interrupted. Then, the power supply to the control unit is interrupted.
