Title: Electrochromic display body
Inventor: YAZAKI MINORU
IPC: G02F1/15
Filed: 1981-12-28
Abstract: PURPOSE:To realize a high response speed and a long life, by using activated carbon and carbon black for an opposed electrode, and using lithium borofluoride or lithium perchlorate, water, and propylene carbonate or gamma-butyl lactone, for an electrolyte. CONSTITUTION:As for an opposed electrode 4, that which has been press-molded by charging an expanded metal 5 of Ti into a core by use of carbon black or activated carbon powder, and a carbonxymethyl cellulose sodium is used. As for an electrolyte, that which has used lithium perchlorate or lithium borofluoride as an electrolyte, has used propylene carbonate or gamma-butyl lactone for a solvent, and has added water of 1.0-2.5wt% is used. When water is added, a response speed of ECD increases, because a part of H<+> is changed to Li<+> and is diffused into the display electrode, and it is caused by a fact that a diffusion speed of H<+> is higher.

Title: Neutral brake device for marine deceleration and reversing machine
Inventor: IMANAKA TOSHIO
IPC: F16H63/24
Filed: 1992-07-17
Abstract: PURPOSE:To abolish braking from high revolution time, and prevent seizure and so on by arranging additionally a timer to operate a neutral brake when constant time passed after being switched to a neutral position in a neutral brake to brake an output shaft according to switching of a deceleration reverser to the neutral position. CONSTITUTION:A device body has a neutral brake 12 to brake an output shaft according to switching of a deceleration reverser to a neutral position. In this case, a position sensor 21 is arranged in the device body so as to detect a switching condition of a forward and backward movement directional control valve to a neutral position. When the forward and backward movement directional control valve is switched to the neutral position, a control signal is outputted to the neutral brake 12 from a control circuit 22 according to a detected signal inputted from the position sensor 21. By the way, a timer 23 is incorporated in the control circuit 22. Thereby, when constant time counted by the timer 23 is elapsed, the control signal is outputted to the neutral brake 12 from the control circuit 22. Thereby, since there is no need to apply braking from high revolution time, seizure and so on of the neutral brake 12 can be prevented.

Title: Manufacture of cellulose triacetate film
Inventor: TANAKA HIROMI
IPC: B29C41/12
Filed: 1987-08-27
Abstract: PURPOSE:To enhance the productivity and at the same time obtain a film having excellent surface properties by a method wherein the time to start the drying of liquid after casting, the angle between the direction of drying air and the surface of a support, the static pressure of the drying air and the gap between the outlet of the drying air and the surface of the support are specified. CONSTITUTION:In case that solution containing cellulose triacetate is cast on a support and, after that, first drying is done by feeding drying air on the surface of the solution after casting, a film is formed under the conditions that the time to start the drying is set to be 15 seconds or less after the start of casting, the direction of the drying air is directed obliquely forward to the running direction of the support and at the same time the angle between the direction of the drying air and the surface of the support is set to be 45-80 degrees, the static pressure of the drying air is set to be 5mmAq or more and the gap between the outlet of the drying air and the surface of the support is set to be 5-50mm. When the drying is done under the conditions mentioned above, favorable and fixed surface properties are obtained after the drying at early stage on a film and, as a result, an excellent film is obtained at all times without being effected by the drying conditions at late stage. Further, since the drying is started quickly after the casting, and no condition thereafter is called in question, the drying speed in the late stage drying can be heightened. Furthermore, troubles such as uneven sinking by blowing and ununiformity in film thickness, which tend to occur when the direction of the drying air flow is parallel or normal to the surface, are solved.

CONSTITUTION:This mechanism is constituted of the linear moving part 1, the moving parts 3, 4 which are supported at one end, are provided on the right and left of the linear moving part 1 and utilize the elastic deformation of the metal and the stage 6 which is provided above the linear moving part 1 to reduce the movement in the moving part 1 and to allow the position control in the very small region. Namely, the moving part A2 is elastically deformed upward and the stage 6 tends to make arc motion around a fulcrum A3 when the force in a horizontal direction (a) is applied on the linear moving part 1. The stage 6 is regulated in the horizontal movement by a fulcrum B5 at this time and the force in the vertical direction acts on the stage 6 to move the stage 6 in the vertical direction. The ratio of the moving quantity of this time can be determined as desired by the thickness of the moving part if the deformation of the moving part is within the elastic deformation. The large ratio of the moving quantity is obtd. in this way without requiring the formation of the device to a larger size.

Abstract: PURPOSE:To obtain a magnetic bubble memory element containing a simple and inexpensive timing generator by juxtaposing a housekeeper unit having a major line pitch smaller than that of an on-chip cache unit on the same side surface of a chip. CONSTITUTION:A storage loop 261 and a cache loop 260 connected to a major line 230 having a generator 220 and a detector 240 at its both ends by a through- swap gate and via a replicate transfer gate 250. While a housekeeper unit 211 contains a single bit length minor 262 connected to a major line 231 having a generator 221 and a detector 241 at its both ends and with approximation to the major line 230 of the unit 210. These unit 210 and 211 are juxtaposed to each other on a chip 200. The noises induced from a driving coil can be reduced since the detectors 240 and 241 are set adjacent to each other. Furthermore the number of gate pulses to be generated from a timing generator can be reduced down to half the conventional number since the gate timings are exactly equal to each other between the function parts of both units 210 and 211.

IPC: H04M11/00
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To provide a digital cordless telephone set in which power consumption is reduced. SOLUTION: Data from a DTE section 1 such as personal computer or the like are received by a data I/F section 2 and the received data are stored in an FIFO section 3. A radio transmission section 4 sends data stored in the FIFO section 3 in a radio signal, based on a VOX function. The transmission based on the VOX function is controlled by a VOX section 5.

Title: Method for transmitting information needing secrecy by first using communication that is not kept secret
Inventor: PATEL SARVAR
IPC: H04L9/32
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To first transmit confidential information by using a communication channel that is not kept secret by allowing a mobile device to receive a public key of a network, generate keyed encryption with a 1st random number and to transmit it and allowing the network to authenticate the communication channel and to perform 2nd encryption by using the 1st random number obtained by decoding it. SOLUTION: A mobile device 20 receiving a public key (PKnet), other information and certification from a network 10 obtains the hush of the other information from the PKnet plus the certification by using the public key PKCA of a certification organization. The mobile device 20 authenticates the PKnet as legal to use it, generates a random number as a session key(SK), enciphers the SK and the identification information ID of the mobile device 20 and transmits them to the network 10. The network 10 obtains the SK and the identification information ID by using a decoding key obtained from the PKnet and establishes an enciphered voice channel between the mobile device 20 and itself by using the SK as an A key. Thus, confidential information is transmitted after being authenticated and also the identification information ID is enciphered so that attack can be prevented.
