Title: Inner focusing system of zoom lens
Inventor: SAKANO MAKOTO
IPC: G02B15/22
Filed: 1982-02-10
Abstract: PURPOSE:To enable focusing up to the nearest distance by moving the lens group except the 1st lens group on the side nearest the object among plural lens groups or part thereof over the entire zooming range for the purpose of focusing. CONSTITUTION:A zoom lens is so constituted that the lens group except the 1st lens group placed on the side nearest the object among the plural lens groups constituting the zoom lens or part thereof is moved over the entire zooming range for the purpose of focusing. The need for moving the 1st lens group which is generally large in aperture and is heaviest is eliminated by such constitution; therefore, the zoom lens can be made correspondingly lighter in weight and the lens group is required to be moved for a shorter length for focusing, thus the zoom lens of simpler constitution is obtained.

Title: Supplying and interrupting device of power source and supplying and interrupting method of power source therefor
Inventor: NUNOKAWA HIROYUKI
IPC: H01H9/54
Filed: 1995-02-07
Abstract: PURPOSE: To reduce cost by providing a control means for closing one contact later than the other contact at power supply, and opening the one contact earlier than the other contact at power interruption. CONSTITUTION: When an operation switch is pushed, a power source is supplied to a control device 7, the device 7 is worked to supply the power source to a load 4. The device 7 makes a current flow to a coil 8 after one second when the current is made to flow to the coil 9 of a relay, thereby closing a contact 3 after one second when a second contact 6 is closed. The device 7 also stops the current-flowing to the coil 9 after the current-flowing to the coil 8 of the relay is stopped, thereby opening the contact 6 after the contact 3 is opened. Thus, since an inexpensive contact with low durability can be used as the contact 6 though the use of a highly durable contact such that it is never damaged every by large current or spark as the contact 3 is necessary, a supplying and interrupting device 1 for power source can be made inexpensive.

IPC: G11B23/30
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To improve the sliding property between a memory detecting part and a tape cassette by providing a memory having an input-output means for writing or reading information in a case, providing the input-output part in the case while making it face the outside surface of the case and arranging it while shifting it from the outside surface of the case to the direction of the inner side of the case by a prescribed dimension to make the damage to the part avoidable. SOLUTION: When a tape cassette 1 comes down in the direction of an arrow, a terminal 142c is brought into contact with the rear edge of a lower case 1b to be deflected from a real line to the direction shown by a dotted line and after a contact part 144c slides on a first housing recessed part 14, the terminal 142c is brought into contact with a resist part 143c. A positioning pin 145 is engaged with a positioning hole 12 and the positioning of the cassette is performed and also the identifying member 146 of a push switch detects the presence or absence of an identification hole 13. Thus, even when the pitch of metallic thin films is narrowed as the cassette is miniaturized, the contact operation between the resist part 143c and the terminal 142c is performed with high accuracy.
