Title: Automatic wiring method
Inventor: KATO ICHIRO
IPC: G06F17/50
Filed: 1986-09-09
Abstract: PURPOSE:To ensure a high wiring factor at high speed in an automatic wiring system by combining the characteristics of a riber method that assures the high-speed searching properties and a highly efficient wiring procedure and the characteristics of a meys method that always detects a route if exists. CONSTITUTION:A searching segment 3 moving down from a start point 1 of a pin pair along a peculiar line 2 having its search priority direction set downward travels along a fault 4 and avoiding this fault 4 at the right side. Then the segment 3 hits a fault 5 and carries on searching like a searching segment 6. When the segment 6 meets the line 2, the searching direction of the segment 6 is changed to the down side with preference to be followed by a searching segment 7. Then the segment 7 hits the fault 5. At this time point, the latest spot where a searching action is carried out on the line 2 is equal to a peculiar point 8. The searching job is taken over by a searching segment 9 and reaches a closed loop point 10 so that a fault exists at a pointer near the right side of a traveling course. Then the searching segment travels again by a right moving rule to perform the searching job like the segment 6.

Title: Control method for rds receiver
Inventor: RYU KOICHI
IPC: H04H20/28
Filed: 1987-08-27
Abstract: PURPOSE:To listen to a broadcast program of the same network in an excellent reception state, by reading a frequency data of the same network stored in a memory when the reception state of a broadcast wave during reception is deteriorated so as to switch the reception frequency to a frequency represented by the readout frequency data. CONSTITUTION:Whether or not a reception signal level VS of a broadcast wave in a frequency fD during reception is a set level V1 or below is discriminated from the output of a station detection circuit 20. When the reception state of VS below V1 is consecutive for a prescribed time (t) or over, the frequency of the network station group is read from the memory 15 and set to a frequency divider of a PLL circuit 2a. Thus, the reception frequency is changed to the broadcast frequency of other broadcast station of the same network. When the new VS is larger than the V1, the reception state is maintained. On the other hand, when the VS is lower than the V1, the original broadcast wave is received. It is repeated till the broadcast wave of the VS larger than the V1 is detected in the network station up to which the broadcast station of the frequency fD belongs.

Title: Eyesight increase training unit
Inventor: MATSUZAKI ISAO
IPC: A61F9/00
Filed: 1988-08-29
Abstract: PURPOSE:To individually and easily use the title device and to show utility the same as that of a massager by giving a light-transmission window against which eyes can be abutted and periodically and automatically brightening/darkening the window. CONSTITUTION:When both eyes are abutted against a visual field window under a closed state, and the unit is started, first, the visual field window becomes a bright state. Immediately, the irises of the eyes are extended, and pupils are contracted. Next, the eyes trace a black point to fly about and are made into a state in which the eyes stare at the black point at an extremely close position. Consequently, corpus ciliares are made into a relaxed state like that in watching at a near point. After several seconds, the visual field window automatically becomes a dark state. Immediately, the irises are contracted, and pupils are expanded. Next, the eyes stare at the center part of a dark part. Namely, the eyes are made into another state in which the eyes stare at an infinite far point, and corpus ciliares are made into a tense state like that in watching the far point. When the brightness and darkness of the visual field window are periodically changed, the irises and the corpus ciliares repeat relaxation and tension, and thus, as the result, the vision moving mechanism of the eyes can be strength.

Title: Lay system
Inventor: ARAI MASAKI
IPC: G06F13/00
Filed: 1996-08-13
Abstract: PROBLEM TO BE SOLVED: To automatically possess a client (CL) address connected to a router at the destination after moving by issuing the setting request of the CL address to the router by detecting a router address at a place where the router is installed based on the information of the place at the new destination to be inputted by the CL. SOLUTION: When a user moves a CL 2 to another place and inputs current position information, the CL 2 retrieves a correspondent relation file 31 and possesses the IP address of a router 1 installed at the place whether the CL is moved and continuously, while using that IP address, the setting request of IP address of the CL 2 is issued to the router 1. When the setting request of the IP address is received from the CL 2, the router 1 selects the non-used IP address out of spare IP addresses registered in a host file 30 to report the CL 2. Thus, only by inputting the information of the place to which the CL is moved, the user can automatically possess the IP address connected to the router 1 installed at that place.

Abstract: PURPOSE: To enhance a current valve per the unit channel of a high withstand voltage MOS type semiconductor integrated circuit and a switching speed by changing the thickness of a gate insulating film correspondent with the potential difference between the gate and the substrate of a transistor. CONSTITUTION: In a high withstand voltage MOS type semiconductor integrated circuit constituted of MOS transistors, the thickness of the gate oxide film 7 of a MOS drive in which the potential difference between a gate and a substrate is always small is set at 300Å. Since an output voltage is applied to a gate electrode 9 from a gate control circuit, an input voltage is not fully applied or because of LOCOS-drain structure, a LOCDS-drain oxide film 8 is thickened to increase the withstand voltage of a drain, the thickness of the gate oxide film 7 can be set to 300Å. Also, the thickness of the gate oxide film 6 of a MOS control circuit in which the potential difference between the gate and the substrate becomes large or small is set at 800Å.  This is the case where an input voltage is fully applied to the gate electrode 9, and it is a thickness which can be guaranteed with respect to an allowable input voltage.
