Title: Keyless entry system
Inventor: HIGUCHI YOSHIO
IPC: H04Q9/14
Filed: 2000-02-14
Abstract: PROBLEM TO BE SOLVED: To secure safety by varying a code every time it is sent; and determine whether a door is open or closed through one-way communications alone. SOLUTION: In a transmitter 11, the number of requests to open or close the door is counted by a transmission counter 112. A seed value in a seed storage part 111 is renewed at each transmission and encoded by an encoding part 113, with this encoded value being transmitted by a transmitting part 114, together with the data of the transmission counter. In a receiver 12, the number of times of transmission during the previous proper process and data for checking are retained respectively in a transmission counter 121 and a seed storage part 122. The seed value is anticipated based on the data renewed by the transmission counter 121. A verifying part 126 compares the encoded seed value anticipated with the encoded seed value transmitted thereto to determine whether the door is locked or unlocked.

IPC: G01N15/06
Filed: 2000-02-16
Abstract: PROBLEM TO BE SOLVED: To provide a charged fine particle measuring instrument, capable of highly accurately measuring the number concentration of fine particles extremely low in number concentration, suspended in gas under pressure conditions ranging from atmospheric pressure to a vacuum. SOLUTION: When gas-containing charged fine particles is introduced from a gas inlet pipe 3, gas flows in the internal space of a center electrode 6 by the pressure difference between the gas inlet pipe 3 and an exhaust pipe 4 and discharged to the outside from the exhaust pipe 4 through the ion collector 7 of the center electrode 6. At this time, the gas flowing in the internal space of the center electrode 6 collides with the ion collector 7, and a part is repelled to be discharged to the internal space of the center electrode 6 to collide with an ion collector 11. The charged fine particles, contained in the gas collide with the metal screens 9, 9, 13 of the ion collectors 7, 11, to discharge charge and the current generated as a result flows into a preamplifier 19 from the ion collectors 7, 11 through a support stand 15.  This weak current is amplified by the preamplifier 19 to be measured by an ammeter 20.
