Title: Leap preventing device for air balance type balanced cargo handling device
Inventor: NAKASUJI KOICHI
IPC: B66F19/00
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To suppress a leap phenomenon to a small quantity by providing an atmospheric release valve releasing the pressure of the balance pressure chamber of a pneumatic cylinder to the atmosphere when a load detector detects no load, and giving a time lag until a pressure control valve is switched to the pressure corresponding to no load after the atmospheric release valve is operated. SOLUTION: When a cargo is conveyed, a load/no-load selector valve 11 is switched to the load side, a signal cutoff valve 14 is opened, a load detecting valve 13 is closed, and the balance pressure corresponding to the weight of the cargo is fed to a balance cylinder 1. When a no-load state is generated by the drop of the cargo, the load detecting valve 13 is communicated, the discharge pressure of a pneumatic source 3 switches an atmospheric release valve 5 to release the balance pressure of the balance cylinder 1 to the atmosphere. When the balance pressure is released to the atmosphere, an arm tends to lower by its tare weight, but the load/no-load selector valve 11 is switched to the no-load side at a time lag specified by the opening of a throttle valve 16, and the stationary state of the arm in the no-load state is maintained.

Title: Mechanical pencil
Inventor: ENDO KAZUNORI
IPC: B43K25/02
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To realize a favorable delivering operation by energizing a lead tank rearward by the elastic force of a clip arranged on a barrel. SOLUTION: A projection 8 is made elastically deformable inwards to a lead tank 2 due to a notched part 9. The clip 11 has an elasticity toward the inside of a barrel 1, thereby energizing the lead tank 2 rearwards at all times. Accordingly, when a knock cap 7 is depressed, the lead tank 2 advances and, at the same time, the projection 8 of the lead tank 2 elastically deforms the clips 11 so as to separate from the barrel 1. In addition, when the elastic force of the clip 11 is strong, the projection 8 elastically deforms inward the lead tank 2. At this time, a chucking body 3 also advances and expands, thereby delivering a lead. Then, when the depression of the knock cap 7 is released, the lead tank 2 is restored to its initial position through its rearward depression by means of the elastic restoring force of the clip and the elastic restoring force of the projection 8.

Title: Designating method for magnification/reduction of picture
Inventor: ASAU RIE
IPC: G06T11/60
Filed: 1987-05-19
Abstract: PURPOSE:To realize the optional selection for magnification/reduction between the pictures similar to an original rectangle and the pictures not similar to said rectangle and to improve operability of a document processor, by setting a magnifying/reducing function with variation in accordance with the direction of an auxiliary line for magnification/reduction. CONSTITUTION:The markers are displayed at the middle points of four sides and four apexes of a rectangle to designate the magnifying/reducing direction to the pictures within the rectangle set for magnification/reduction. Then a user designates one of those displayed markers via a pointing input device. Thus the auxiliary lines are displayed in the upper direction, the lower direction, the left direction, the right direction, the upper left direction, the lower left direction, the upper right direction and the lower right direction respectively based on and through the designated marker. If the magnifying/reducing direction is shown by the auxiliary lines set in the upper left direction, the lower left direction, the upper right direction and the lower right direction, for example, the magnifying/reducing directions are designated on those auxiliary lines via the pointing input device. Thus a size can be designated after magnification/reduction without changing the ratio between the vertical and horizontal sides. Thus it is possible to optionally select the magnification/reduction between the pictures similar to an original rectangle and the pictures not similar to said rectangle when the pictures are interactively magnified and reduced within a rectangle.

Title: Communication method for multi-drop asynchronous communication
Inventor: KODA EIJI
IPC: H04L29/08
Filed: 1993-05-24
Abstract: PURPOSE:To enable communication between a master station and all slave stations by selecting communication attributes for enabling all the stations to perform the communication and performing unification to the selected communication attributes even when the slave stations of the different communication attributes coexist. CONSTITUTION:The master station confirms the response state of the slave station at the time of the previous communication in a response state table. Then, when the slave station responded, polling is performed to the slave station with the communication attributes of a communication speed, a communication mode and a communication code at present, etc. On the other hand, when the slave station did not respond in the response state table, the polling is performed to the slave station with the specified communication attributes. The slave station uses the specified communication attributes and informs the communicable communication attributes to the master station. Thus, the master station decides the optimum communication attributes for enabling the communication with all the slave stations and informs and sets them in the respective slave stations. Thus, even when the slave stations at different specifications coexist, the communication with all the slave stations is secured.
