Abstract: A control device for an internal combustion engine provided with a combustion control part successively performing at least first main fuel injection and second main fuel injection and making the fuel burn by premix charged compressive ignition so as to cause generation of heat two times in stages inside the combustion chamber and cause the pressure waveform showing the change along with time of a rate of cylinder pressure rise to become a two-peak shape. The combustion control part calculates a second premix time of fuel injected by the second main fuel injection with air, reduces the injection amount of the second main fuel injection so that the second premix time becomes a first threshold value or more and performs after fuel injection after the second main fuel injection when the second premix time is less than the first threshold value, and injects the amount of fuel reduced from the injection amount of the second main fuel injection by the after fuel injection.

Abstract: A keyboard input apparatus, where a plurality of main keys are pressed for character inputting operation. Five keys are set individually as character keys for inputting characters “A”, “I”, “U”, “E”, and “O” of the Alphabet expressing vowels. Further provided are key input detectors to detect the number of key pressing operations of each of the main keys, and a key input processor for outputting the character keys corresponding to the number of key pressing operations. Setting of in the Japanese and English language frequently used vowels on independent keys enables inputting of vowels by only a single key pressing operation and when compared with a conventional art where a plurality of key pressing operations are required, the number of key pressing operations can be reduced at the time of inputting vowels, whereby manipulation of the apparatus and the inputting speed can be improved.

Abstract: A screen display key input unit. A screen display has a series of keys which can be operated by touching with a pen, a mouse or the like. Each of the keys are defined with first and second graphic character codes. A key input device points out a key display area on the screen while a selection processor selects one of the two graphic character codes on the key by determining the difference of key selection operations of the key input. The two graphic character codes are defined on each of the keys so that the number of keys shown on the screen is reduced as compared to conventional unit where each key is defined with a single graphic character code.

Abstract: A keyboard-type input apparatus has a main key area consisting of at least fifteen keys arranged in a three-line and five-column state to include a basic side either on right or left side of the column, of which two-column belongs to the basic side being provided as a vowel sound area to input vowel sounds and other columns composed of three-column being provided as a consonant sound area to input consonant sounds.

Abstract: In a packaging structure, a tongue-like portion is formed in one end portion of a base to extend toward an end of the one end portion. A wristwatch, having a pair of watchbands with a band keeper being provided on one of the bands, is placed on the base, and the tongue-like portion is inserted into an opening of the band keeper through a gap of the band keeper and the corresponding watchband. A pillow portion is formed in the one end portion of the base at a region which is nearer to the end of the one end portion than the tongue-like portion. The pillow portion covers the tongue-like portion, and an extending end of the one of the watchbands lays on the pillow portion in a longitudinal direction of the base.

Abstract: Shock absorbing members are attached to an outer rim of a back surface of a wristwatch case body at 6- and 12-o'clock portions thereof, and they extend outward and curve downward. Each of the shock absorbing members has rising portions extending from its both side ends and which are freely swingably attached to the wristwatch case body to a circumferential surface of the wristwatch case body. In addition, a part of a front surface and the circumferential surface of the wristwatch case body are covered by a first cover member made of soft synthetic resin, and the first cover is partly covered by a metal-made second cover member. When shock is applied to the front and circumferential surfaces of the wristwatch case body, the shock is reduced or absorbed by the rising portions of the shock absorbing members. When shock is applied to the back surface of the case body, the shock is reduced or absorbed by the shock absorbing member.
