Abstract: A SRAM having its memory cell constructed to include transfer MISFETs to be controlled by word lines and a flip-flop circuit having driver MISFETs and load MISFETs. Plate electrodes of large area fixed on predetermined power source lines are arranged over the load MISFETs such that the plate electrodes over the offset region of the load MISFETs are formed with an opening. A silicon nitride film having a thickness permeable to hydrogen but not to humidity is formed over the transfer MISFETs and the driver MISFETs formed over the main surface of a semiconductor substrate and the load MISFETs formed of a polycrystalline silicon film deposited on the driver MISFETs.

Abstract: In a chord progression input/modification device, when a key and a single or two successive reference chords are designated by a user, available chords are acquired and displayed. Any one of the available chords can be used, in consonance with musical theory, to follow or substitute for the single reference chord, or to be inserted between the two reference chords for generating a modified chord progression. The chord progression modification device may be installed in an electronic musical instrument.

Abstract: In a hydrogen treating plant which includes a recycle gas line having a reactor for regenerating a hydrogen sulfide by hydrogenating sulfur and an H2S absorber for absorbing the hydrogen sulfide generated in the reactor, and includes the liquid cyclic line circulating liquid for absorbing the hydrogen sulfide in the H2S absorber therein, a refrigerant unit provided in the liquid cyclic line which is lower temperature and lower pressure relative to the recycle gas line.

Abstract: Electronic musical instruments in which if a chord is specified for a melody, a scale suitable for the chord function can automatically be selected for the specified chord type to play the melody. The electronic musical instruments have means selecting a scale corresponding to a chord when a chord progression and a key are specified For a melody pattern, and pitch shift means which performs transposition of each tone according to the chord thereby to modify the pitch so as to accord with the scale.

Abstract: Disclosed is a process for producing L-threonine, which comprises culturing an L-threonine-producing microorganism belonging to the genus Escherichia and having a resistance to at least one of L-phenylalanine and L-leucine in a medium until L-threonine is produced and accumulated in the culture, and recovering L-threonine therefrom.

Abstract: An auto-accompaniment apparatus, which selects and forms a chord that can be naturally linked with currently generated chord tones from a plurality of inversion variations, and generates the formed chord as the next accompaniment tones, is disclosed.The auto-accompaniment apparatus has an accompaniment pattern memory (1) for storing note data strings for performing an auto chord accompaniment operation on the basis of reference chords, and offset memories (3, 5) for storing tone pitch offsets of the note data with respect to the reference chord in units of chord notes of different chord names in correspondence with a plurality of chord inversion variations and root names. The plurality of offsets corresponding to the chord inversion variations are read out from the offset memories on the basis of a pre-programmed chord progression sequence or chord information detected based on play information. Of the readout offsets, an offset close to the currently generated chord tones is selected by a selector (31).

Abstract: A musical tone data compensation apparatus which detects chord components in a performance data stored in accordance with operation of a keyboard and modifies touch data of each tone composing a chord. New touch data are generated by compression or expansion of each difference in touch data with referring to a representative touch data in a block of chord tones, so that emphasis or smoothness is given to a sequence of chords.

Abstract: Disclosed is a process for producicng L-threonine, which comprises culturing in a medium a microorganism belonging to the genus Escherichia and having a resistance to cysteine or cystine, or their analogue and an ability to produce L-threonine until L-threonine is accumulated in the culture broth, and recovering L-threonine therefrom.

Abstract: The present invention relates to a method of unloading a catalyst from a reactor wherein the reactor is filled with mixed liquid of condensed ring aromatic hydrocarbon having a required number of ring members, i.e. preferably 2 to 4 ring members, and gas oil, to wet the catalyst so as to form a coating of film on the catalyst before unloading the catalyst from the reactor.
