Title: Automatic fire extinguisher
Inventor: ITOKAWA HITOSHI
IPC: A62C31/03
Filed: 2001-04-17
Abstract: PROBLEM TO BE SOLVED: To operate an automatic fire extinguisher in good condition regardless of the peripheral environment of a temperature detecting member.

Title: Identifying method of new point in source audio signal
Inventor: JONATHAN T FOOTE
IPC: G10L15/04
Filed: 2001-05-11
Abstract: PROBLEM TO BE SOLVED: To provide a method for detecting automatically a changing point in a music or voice. SOLUTION: The method, for determining a changing point or a new point within audio signals is performed by, measuring the self similarity of the signals. A computational equation is used to determine value vectors of a parameter display for every time window in the signals. Then, mutual similarity and self similarity among the values of respective parameter displays are determined in all regions of the past and the future windows. An effective point of a new reference has high self similarity in the past and the in the future and low mutual similarity. The range of the time difference between 'the past' and 'the future' is made variable to change the sacale of the system. As a result, the degree of new reference of source audio at an arbitrary time point is measured.  This method is used for various applications including segmentalizing spoken language or music, indexing, beat/tracking and summarizing.

Title: Locking mechanism of door for casing
Inventor: ISHII TAKUMA
IPC: E05B61/00
Filed: 2001-05-15
Abstract: PROBLEM TO BE SOLVED: To prevent such problems with a locking mechanism of prior art that normally (in the state of being locked) a load (door weight) was always applied to a key body which leads to damage to the key body, and when a door is operated to open in the state of being locked, an excessive load is applied to the key body which leads to damage to a key. SOLUTION: A cam is used to transmit rotation from the key body to the locking mechanism so that a key body part is not engaged directly with a locking part by forming these parts independently of each other. Normally (when the door is closed), the key body (including a cam) and the locking mechanism come in non-contact with each other. In unlocking, the locking mechanism is operated by the cam provided on the key body so that the strength of the locking mechanism can be determined only by the structure of the locking part.
