Title: D/a converter
Inventor: WAKIZAKA HIROSHI
IPC: H03M1/74
Filed: 1999-12-02
Abstract: PROBLEM TO BE SOLVED: To provide a D/A converter capable of easily performing a highly accurate test by the incorporated inspection circuit of simple constitution. SOLUTION: A test mode is set in this D/A converter 100 and a current switch 50 for a test is turned ON and OFF in linkage with the current switch 20-1 of the constant current source 10-1 of a lowest order. Thus, when the current switch 20-1 of the lowest order is ON (that is at the time of an odd number), the constant current source 10-1 and the constant current source 40 for the test are synthesized and output is performed through the current switch 50. In the state, in the case of successively inputting certain even number data (1000) and odd number data (0111), since an error is present in an actual D/A converter, fluctuation for the error is generated in the output signals of the D/A converter.  Then, the AC component of the fluctuation is compared with a reference vague by using a window comparator circuit 150 and whether or not the difference of two data is within a stipulation is discriminated.

Title: Server device and server system
Inventor: MOTOOKA SHIGEAKI
IPC: H04L12/18
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To facilitate construction and modification of the system. SOLUTION: The server device D1 once receiving a signal requesting video of a server device D2 from, for example, a customer C1 sends a signal requesting the video of the server device D2 as if the device were a customer to the server device D2. The server device D2 supplies video picked up by its own camera 2 to the server device D1 as the customer according to the received signal. The server device D1 supplies the video to the requesting customer C1. Namely, each server device selectively supplies video of its own camera or repeats video from another server device according to a request signal. Any server device has the same configuration and two server devices which are connected to each other operate equally as both customer and a server device, so the system is easily constructed and modified.

Title: Lock with protector
Inventor: NAKAMOTO SUKEMASA
IPC: E05B53/00
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To protect a slide button and facilitate the packaging for transportation by preventing a hook from projecting in those cases other than prescribed means. SOLUTION: A protective member 17 having a hole through which a slide button 4 can be inserted is installed, and the height of the protective member 17 is set generally at the same height as that of the projected slide button 4. By this, the head part of the slide button 4 is pressed by a pin 19 installed on a striker 21 side only when a door 22 is closed so as to maintain the locking function of the door and because, when the door 22 is open, the slide button 4 cannot be pushed from the outside, a bending of hook due to careless handling can be prevented by preventing the hook from being projected by those means other than prescribed means. Also, because any obstacle does not touch the slide button 4 directly from the outside, packaging for transportation can be simplified.
