Title: Cyclic nucleotide phosphodiesterase gene
Inventor: TANAKA TOSHIO
IPC: A61K48/00
Filed: 2000-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a new cyclic nucleotide phosphodiesterase, a gene encoding the enzyme, a method for producing these, and uses of these. SOLUTION: A full-length cDNA encoding a new cyclic nucleotide phosphodiesterase (PDE10A) was successfully isolated from a human cDNA library. Since PDE10A has structure different from known PDE, PDE10A was assumed to belong to a new PDE family. PDE10A has an ability of hydrolyzing both cAMP and cGMP, a Km value lower than known PDE families, and sensitivity properties to various PDE inhibitors different from known PDE families. Expression of PDE10A was high especially in the putamen and caudate nucleus. PDE10A is useful as a target for developing a medicine having a new effect.

IPC: H04W48/04
Filed: 2000-10-19
Abstract: PROBLEM TO BE SOLVED: To provide an automatic control system for portable electric equipment, with which a limit is applied to portable electric equipment only inside a space requiring the limit and that limit is not applied outside that space. SOLUTION: In this portable electric equipment control system, automatic switching is enabled without necessity to ask a person of photographing inhibition or flash use inhibition.

Title: Line supervision system
Inventor: HAKII YUJI
IPC: G07B15/00
Filed: 2000-10-26
Abstract: PROBLEM TO BE SOLVED: To provide a line supervision system reduced in facility cost with a simple structure by performing a data communication through a common information signal transmission line regardless of the number of parking squares or the number of beacon devices. SOLUTION: A line supervision device 1 controls a multiple dwelling house line exchanger EX-H parking lot line exchanger EX-P to connect either one of a plurality personal computers and roadside machines to a common relay line SL. Therefore, at least one relay line SL is sufficient regardless of the number of the personal computers and roadside machines. Since an onboard ID is not used for vehicle discrimination as in the past, the communication with not only the own vehicle but also the onboard machine of a rent-a-car or another person's vehicle can be performed from the dwelling house side only by parking it in a prescribed position. Further, since the switching of communication connection is controlled between the dwelling house side and the parking lot side, this system is flexibly conformable to a change of dwelling house resident, parking lot user, or the like.
