Title: Galvanomirror supporting device for pickup device
Inventor: IKEGAME TETSUO
IPC: G02B26/10
Filed: 1989-02-02
Abstract: PURPOSE:To obtain a galvanomirror supporting device for an optical pickup which is thin and easy to assemble by decreasing the number of coils and magnets used for the supporting device. CONSTITUTION:A pair of magnetic field means 3 and 5 are set at both sides of a device together with a reflecting means 2 set between both means 3 and 5. The means 2 has a light reflecting surface which is tilted by a necessary angle against the direction of the magnetic flux and also has a pair of drive means 6 which produce the driving force in cooperation with the means 3 and 5. Then the means 2 and 6 are supported in a drive enable way by a pickup device fixing member 4 via a supporting member 7. Thus each of both means 3 and 5 consists of the least number of parts and the means 2 and 6 are supported by a supporting means set at the side of the drive means so that they can move in a body. In such a constitution, the number of parts are minimized together with reduction of the thickness for a galvanomirror supporting device.

Title: Character display device
Inventor: YAMASHITA KENSUKE
IPC: G06F17/21
Filed: 1993-02-10
Abstract: PURPOSE:To increase display characters of the display device and make the characters attractive and easy to read in case of processing for wherein a punctuation mark is inhibited from being at the head of a line. CONSTITUTION:In electronic equipment which displays a Japanese character string, the CPU judges the punctuation marks inhibited from being at the head of a line (a), and judges whether or not the character can be put together with its last character (c) when the punctuation mark inhibition processing is performed and performs processing (d) for full-sized characters by putting the period and a HIRAGANA (cursive form of Japanese syllabary) font together when the processing is possible, but performs processing (b) for putting the character to the leftmost end (head) of a next line when the processing is impossible. Consequently, the display device which is relatively small in the number of display columns is increased in the number of characters which can be displayed in one line to show much information to a user. Further, the punctuation marks are positioned at the left end of the display device, so the display device is made easy to see and improved in readability.

Then, the pad 10 is elevated, and is moved onto a magazine 3 by means of a ball screw 18. Subsequently, the pad 10 is lowered onto a guide mask 24, then the vacuum is released. Accordingly, this casues the article 2 to fall down into a housing groove 4. Then, the magazine 3 is excited to the X direction by a feeder 21. This allows the article 2 to be guided and housed in the housing groove 4 of the magazine 3 along a taper guide surface 23. This configuration enables the simple configuration of a device to be employed associated with a highly augmented work efficiency.

Title: Control system for encoding of binary picture signal
Inventor: YOSHIDA SHIGERU
IPC: G06T9/00
Filed: 1986-02-04
Abstract: PURPOSE:To moderate constraint from an encoding method to a compression ratio, and to obtain a large compression ratio even in a variable density area by identifying the variable density area by every prescribed plural pieces of picture element pattern units, and making the plural pieces into a forecast encoding. CONSTITUTION:A counter 46 counts the number of variable patterns in consecutive picture element patterns, and a comparator 47 compares a counted result. An FF48 holds an identified result, and uses it in the selection of the encoding of the consecutive picture element patterns stored at shift registers 53-56. A ROM49 inputs a signal 43a from a line counter, and the contents of shift registers 42 and 53 to an address. The shift registers 42 and 53 become an encoding pattern and a reference pattern respectively, and the ROM49 outputs an appearance order when the encoding pattern is a gradation pattern, and when it is not the gradation pattern (non-gradation pattern), outputs a signal which represents the fact. Therefore, the content of a shift register 50 represents a forecasting result corresponding to the picture element patterns of the shift registers 53-56.

Title: Inter-node message outrun processing system for decentralized system
Inventor: YAMANAKA OSAMU
IPC: G06F15/16
Filed: 1988-02-05
Abstract: PURPOSE:To detect the outrun of messages and to perform the same processing as in a case where no outrun occurs by providing a transaction state transition control table through a decentralized system. CONSTITUTION:A client side system 1 is connected to a server side system 2 via a communication means in a decentralized system. A transaction state control processing part 6 receives a decision instruction retransmission request in a restart committing state and therefore can decide the outrun of messages based on a transaction state transition control table. In case the part 6 receives the response of an error of the decision instruction, the transaction state is shifted to a restart waiting state based on said control table. Then the part 6 transmits again a decision committing instruction. The transmitting process of the decision committing instruction and the transaction state set after said transmission are equal to a case where no outrun of messages is produced. Thus a normal process can be continued.

Filed: 1990-02-02
Abstract: PURPOSE:To shorten a switch pitch of a switch that separates a doughnut-like contact from a circular contact situated in its ring through a diaphragm by specifying the shape of the doughnut-like contact. CONSTITUTION:Each contact 27 of a shape of doughnut that is arranged in parallel on a substrate is separated from each circular contact 28 provided almost in the center of the doughnut shape, through the deformation of a diaphragm.
