Title: Gateway device, method for specifying terminal for the gateway device, and recording medium recording terminal specific program and readable by computer
Inventor: FUKUYAMA NORIYUKI
IPC: H04L29/06
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To facilitate a call operation on a packet exchange network by a client from a public switched telephone network PSTN. SOLUTION: The gateway device 3 connects a PSTN1 to a packet exchange network 2 to which pluralities of information terminals are connected. The gateway device 3 is provided with a recognition means, an incoming call notice means and a connection means. The recognition means recognizes information terminals on the packet exchange network 2. The incoming call notice means that receives an incoming call from the PSTN1 informs all the recognized information terminals of the incoming call. The connection means connects the PSTN1 to the information terminal first replying the incoming notice. Also the gateway 3 can use a broadcast address or a multicast address in order to inform all or pluralities of information terminals on the packet exchange network 2 about the arrival of incoming call in terms of polling.  Besides, the gateway 3 can assign caller identification information and an incoming telephone number on the PSTN in advance to information terminals in order to select incoming call notice destinations. Otherwise it is preferred to use an automatic answering telephone terminal that can always accept an incoming call.

Abstract: PURPOSE:To decrease the number of equivalent phase shifters per one element antenna, by adjusting the phase shift of an output of one element antenna out of the two element antennas corresponding to two outputs of a variable distributors and eliminating a phase shifter to be connected to an antenna. CONSTITUTION:A high frequency signal from a transmitter 4 is distributed and phase-shifted at variable distributors 8-1-8-n so as to obtain a desired phase distribution in all element antennas 1-1, 1-2-1-2n-1, 1-2n and the element antennas 1-1, 1-3-1-2n-1 of an odd number order, and phase-shifted at phase shifters  2-2, 2-4-2-2n so as to obtain a desired phase distribution in the element antennas 1-2, 1-4-1-2n of an even number order. Since the phase can be adjusted for the output of the element antennas 1-1, 1-3-1-2n-1 of an odd number order with the variable distributors 8-1-8-n, phase shifters to be connected to the element antennas can be eliminated.

Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To reinforce a simultaneous ON preventing action by increasing the size of a driving reverse bias voltage for simultaneous ON prevention without increasing voltage loss and energy loss. SOLUTION: In this changeover switching means, DC power sources 1 and 2 for increasing a base reverse bias voltage for the simultaneous ON prevention are additionally connected, and when transistors 3 and 4 are to be simultaneously turned ON, a short-circuit current is to flow from the transistor 3 to the transistor 4, however, the short-circuit current is to flow through an electrode capacitance between the emitter and base of the transistor 3, the DC power sources 1 and 2 and the electrode capacitance between the base and emitter of the transistor 4 without passing through diodes 7 and 8 and the diodes 6 and 5 by the action of the DC power sources 1 and 2. As a result, the transistors 3 and 4 are strongly base reverse biased and the simultaneous ON preventing action acts more strongly than before.  Also, since the need of enlarging the respective forward voltages of the diodes 7 and 8 for the reinforcement of the simultaneous ON preventing action is eliminated, the respective losses are not increased.

Abstract: PURPOSE:To prevent a bulldozer automatic transmission, provided with a torque converter and a multistage transmission so as to perform automatic speed change at the time of vehicle speed reaching a speed change point, from performing frequent speed change due to sudden load fluctuation which causes the lowering of traction performance. CONSTITUTION:A control device 26 is provided and connected to an engine speed detector 3, a body inclination detector 4, a torque converter output shaft rotating speed detector 6, a transmission output shaft rotating speed detector 16 and the speed stage control valve 20 of a transmission.

IPC: G03C1/00
Filed: 1987-06-30
Abstract: PURPOSE:To improve solvent resistance of a pattern by using a specified photoreactive crosslinking resin compsn. CONSTITUTION:A photoreactive crosslinking resin compsn. consists of a polymer (e.g. polyvinyl cinnamate) having crosslinking functional groups and photoreactive functional groups, and a low molecular compd. (e.g. methyl cinnamate) which can cause photoreaction with the afore-mentioned polymer. After forming a thin film 1 from said compsn. on a substrate 2, the thin film is exposed through a photomask 3 to cause a reaction in the film 11 at the exposed part. Then, the low molecular compd. 111 at the unexposed part is removed under reduced pressure and/or by heating to cause decrease of its volume. The whole body of the film is crosslinked by exposing the whole surface of the film simultaneously or after decreasing the volume. Thus, a pattern 13 is formed. By this process, gratings or lenses having high solvent resistance are formed in large amt. inexpensively.
