Abstract: A position obtaining device includes a processor. The processor, in response to a condition being met, derives a first attitude angle as an attitude angle of the device based on first light sources and positions thereof on an image obtained by a first camera; in response to the attitude angle of the device being known, derives a three-dimensional position of the device based on two or more second light sources and positions thereof on an image obtained by a second camera, and in response to a predetermined number of second light sources or more being captured in the image, derives the three-dimensional position and a second attitude angle as the attitude angle of the device; and integrates a result of the first attitude angle and a result of the three-dimensional position and the second attitude angle to estimate the attitude angle and the three-dimensional position of the device.

Abstract: Disclosed is a water jet peening method that includes the steps of: preparing a water jet peening apparatus having a supporting member, a first divider plate, a nozzle support body, and a second divider plate; inserting the water jet peening apparatus into a piping in which a structure or electronic device is mounted that is susceptible to damage by a jet of water discharged from a jet nozzle or by shock waves; disposing either the first divider plate or the second divider plate between the jet nozzle and the structure or electronic device; filling water into an internal area formed in the piping between the first divider plate and the second divider plate; and subjecting the inner surface of the piping to water jet peening by allowing the jet nozzle to discharge a jet of water into the water in the internal area.

Abstract: A method accurately inspects whether an IC inlet to be inspected is non-defective or defective in a state in which a large number of IC inlets are formed over an insulating film. The inspection of IC inlets formed over an insulating film is performed by transmitting microwaves to the IC inlets from antennas. To selectively irradiate the microwaves to only one IC inlet to be inspected out of a large number of IC inlets that are formed over the insulating film, a radio-wave absorbing plate is inserted between the insulating film and the antennas, and the microwaves are irradiated to the IC inlet through a slit formed in the radio-wave absorbing plate. The radio-wave absorbing plate is configured such that the slit, which is substantially equal to the IC inlet in size, is formed in a portion of a planar plate that is formed of a radio-wave absorber.

Abstract: In a semiconductor memory device including memory cells, first and second decoders generate first and second selection signals, and a driver circuit generates a drive signal for driving the memory cells. The driver circuit includes a transfer gate, controlled by the first selection signal, thus passing the second selection signal to generate the drive signal.

Abstract: The output buffer circuit according to the present invention comprises: a P-channel type output transistor which is provided between a first power supply terminal and an output terminal and receives an input signal at a gate thereof; an N-channel type transistor which is provided between the output terminal and a second power supply and has a gate connected to a drain of a gate current controlling transistor; a circuit for supplying the input signal to a source of the gate current controlling transistor; and a voltage control generation circuit which generates as a gate voltage of the gate current controlling transistor a first voltage value which is smaller than a value of the power supply voltage for a predetermined time, and further generates a second voltage value which is higher than the first voltage value after the elapse of the predetermined time.

Abstract: An efficient microbiological or biochemical method is proposed for the preparation of an optically active 2-substituted carboxylic acid, e.g., 2-chloropropionic acid, 2-methyl butyric acid and the like, from the corresponding 2-substituted nitrile compound, e.g., 2-chloropropionitrile, 2-methyl butyronitrile and the like, in the form of a racemic body as the starting material The method comprises bringing the starting nitrile compound into contact with a microorganism, such as Pseudomonas sp. MY-1 (FERM BP-2541), Fusarium sp. MY-2 (FERM BP-2542) and the like, capable of converting the nitrile compound into the carboxylic acid in a buffered aqueous medium in which the microbial cells of the microorganism are suspended.

Abstract: Optically active substances are prepared by the asymmetric hydrolysis of ##STR1## with specific microorganisms.

Abstract: A music reproducing method and apparatus for mixing voices input from a microphone and music data displays various information which represents that a musical performance of a piece of music is entering an interlude inserted between singing -portions, i.e., choruses, or is entering a postlude after the choruses are terminated, the information being provided by a screen display or speaker output of the music reproducing apparatus. The information can inform the user of the end of a song when the musical performance enters the postlude, and can inform the user of the end of singing-portions in the song when the musical performance enters the interlude. The information can be related to the music or the like known to the user.

Abstract: Sorbic acid can be prepared by the activity of a specific microorganism on 2,4-hexadienal. This method can be performed under mild conditions and, different from organo-chemical methods, is advantageous because no by-products are formed.
