Title: Variable wavelength optical filter
IPC: G02B26/00
Filed: 1992-03-13
Abstract: PURPOSE:To obtain the variable wavelength optical filter which has small insertion loss due to variation in wavelength by providing a curved filter film movably almost at right angles to the main axis of a parallel light beam at a position where the parallel light beam is crossed. CONSTITUTION:The filter film 30 is sandwiched in a curved shape between glass blocks 32 and 34, which are fixed on a base 36. A projection 36A is formed on the reverse surface of the base 36 and engages a groove 16A formed linearly in the top surface of a substrate 16. This constitution enables the filter 30 to be moved almost at right angles to the main axis of the parallel light beam. Consequently, the angle of incidence on the filter film 30 is varied to vary wavelength characteristics, so the insertion loss is prevented from decreasing as usual owing to rotating operation.

Title: Automobile receiver
Inventor: TAKAHASHI MASAYOSHI
IPC: H01Q1/10
Filed: 1987-03-09
Abstract: PURPOSE:To prevent a wind cutting sound and to improve a neat appearance by giving priority over a receiving with a glass antenna, providing a control circuit to control a motor so as to shrink a pole antenna, and lowering forcibly the pole antenna, when the receiving condition of the glass antenna is excellent. CONSTITUTION:A motor 12 to expand and drive a pole antenna 2 is controlled by a control circuit 13 connected to a microcomputer 11. For example, by the microcomputer 11 at the time of travelling in suburbs, when the receiving condition of a second tuner 8 is made satisfactory, and it is judged that the condition is continued for a certain time, a coil 7d of a relay 6 is demagnetized and a moving contact 7c is switched to a second fixing contact 7b. Since a switch 14 of the control circuit 13 is turned off, a current flows as shown by a virtual line B, the motor 12 is reversely rotated and the pole antenna 2 is automatically decreased. Thus, the neat appearance and the wind cutting sound are improved.

Filed: 1991-02-28
Abstract: PURPOSE: To enable a user to easily describe a tree and also to generate a data structure showing the tree in a memory by showing the attributes to be given to the nodes of the tree in every type of them. CONSTITUTION: A table contains the columns of the levels (depth), the node type names and plural attributes, and a user writes the necessary information into these columns. For example, 0 is written in the level column for a node A that is positioned at the highest part of a tree together with 1 written for nodes B to E as the children of A and the sequence relation of the children reflected on the upper-lower relation respectively. The number of nodes, for example, is written in the attribute column, and a tree shown by this table includes the nodes belonging to the types B to E as the children of the node A as long as both maximum and minimum value are set to 1. In other words, the pointer data can be generated through such interpretation as mentioned above and the user can easily input the pointer data by means of a text editor.

Filed: 1983-03-31
Abstract: PURPOSE:To prevent accumulation of time counting errors and to perform repetitive copying excellently, by controlling the start of time counting for controlling respective copying processes according to the completion of the time counting of the last process, the detection of the specific position of a movable member, etc. CONSTITUTION:A clock from an input device which synchronizes with rotations of a screen drum is counted by the counter circuit of a CPU and when a proper condition detection input which indicates that the screen drum and an optical system are at home positions is supplied from the input device, a sequence control signal varying with elapsed time is outputted to form a latent image on the screen drum. The start of counting for control over the transfer of the latent image to the next insulating drum is controlled after the time counting. Similarly, time counting for image copying is started in response to the home position detection of the screen drum and the completion of the time counting during the latent image transfer. Thus, the accumulation of time counting errors is prevented to perform the excellent repetitive copying operation.

Abstract: PROBLEM TO BE SOLVED: To adjust the titled substance and compsn. By a simple means and to make them repeat sol-gel transformation in accordance with change in the outside environment by using a gelation substance which can reversibly perform sol-gel transformation at critical point of ionic strength as the boundary in the presence of boric acid. SOLUTION: These gelation substance and gel compsn. reversibly perform sol-gel transformation at critical point of ionic strength as the boundary in thepresence of boric acid. In this instance, concn. of boric acid is pref. at least 10 mM and more pref. at least 30 mM. The critical point of ionic strength of this gelation substance is pref. In the range of 0.1-0.5 and more pref. in the range of 0.2-0.4. The gelation substance gels at this critical point or higher and does not gel below the critical point. Therefore, by elevating the critical strength to at least the critical point, it is possible to perform gelation of the gelation substance, i.e., preparation of the gel compsn. It is therefore necessary for gelation to provide an ionic strength of pref. at least 0.2, more pref. at least 0.4.

Title: Paper feeder
Inventor: AMANO TOSHIAKI
IPC: B41J13/076
Filed: 1988-03-10
Abstract: PURPOSE:To prevent paper from occurrence of snaking, wrinkling, etc. by lifting of the paper near a central part of the paper, by a method wherein a disk of which an outer diameter is slightly smaller than the outside diameter of a paper feed roller is provided inside the paper feed roller of the paper feeder wherein the paper is sheet by sheet drawn out to be sent out with the paper feed roller. CONSTITUTION:Paper 11 is sheet by sheet separated from a paper feed tray 1 with a paper feed roller 2 to be sent to a platen roller 4. At that time, a carry speed of the paper is so established as to be slightly faster than a feed speed of the paper. When the paper 11 is likely to be carried with the platen roller 4, the paper feed roller 2 becomes free rotatable by action of a one way clutch. Then, when the paper 11 is dislocated from the paper feed roller 2, the paper feed roller 2 starts to be rotated synchronized with rotation of the platen roller 4 by a group of gears 3, and separates the next paper 11 to be fed. On rotation of this paper feed roller 2, a central part of the paper 11 occasionally swells and is likely to be lifted. However, this lifting is prevented by action of a disk 2b of which an outer diameter is the same as or slightly smaller than that of the paper feed roller 2 so established inside the paper feed roller 2 as to be rotated in one united body with the paper feed roller 2.
