Title: Communication terminal and communication rate setting method therefor
Inventor: HAKAMATA SAYURI
IPC: H04L7/00
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To autonomously set a proper communication rate without setting the communication rate between the operator of a communication terminal and the equipment of a party and to speedily detect the abnormal state of the equipment of the party. SOLUTION: A communication rate setting part 15a reads out and sets one of plural communication rates previously registered in a communication rate file 12, and a transmission/ reception control part 15b sends the setting request of communication at this communication rate to the equipment of the party. The transmission/reception control part 15b discriminates whether a setting response, which indicates confirmation corresponding to this setting request, can be received within prescribed time or not and when the setting response can be received, communication with the equipment of the party is started at the communication rate set at this time. When the setting response can not be received, the communication rate setting part 15a resets the other registered communication rates and the transmission/reception control part 15b waits the setting response from the equipment of the party.

IPC: G01N21/72
Filed: 1985-09-11
Abstract: PURPOSE:To take a measurement with high precision by using lithium as an internal standard element for the concentration measurement of sodium and cesium for the concentration measurement of potassium. CONSTITUTION:A sample 10 to be measured is sucked and atomized by an atomizer 12 and admitted into a flame 14. Lithium and cesium with constant concentration are added to the sample 10.

Title: Thermal head
Inventor: SHIRAKAWA KYOJI
IPC: B41J2/335
Filed: 1988-08-10
Abstract: PURPOSE:To enable the manufacture with good yield and low cost and to maintain printing quality of a high level for a long time by a method wherein a heating resistor layer is formed over from a slant surface to a parallel surface, and a load dispatching material layer is respectively arranged on the slant surface and the parallel surface. CONSTITUTION:Since a glaze layer 12 is largely gently so etched that an almost flat slant surface 14 is formed from a heating resistor layer 13 to an end part of an insulating material 11, i.e. since the slant surface 14 is sloped by an inclination of 10 deg. to 15 deg. capable of being formed easily from a standpoint of fabrication, there is no trouble for etching. Further, heat conductivity of the heating resistor layer 13 is never impaired by action of resilience and deflexion of a platen even by this inclination angle. Therefore, enough pressure contact force is maintained by this fact when ink is solidified by cooling, and excellent printability can be displayed even for rough paper.

Title: Pull in system by pll
Inventor: SAKAMOTO HIROSHI
IPC: H04L7/033
Filed: 1986-08-26
Abstract: PURPOSE:To improve the pull in time at out of synchronism by inserting an amplifier with exponential characteristic between an output of a phase detector and a control input of a voltage controlled oscillator so as to improve the frequency stability at the steady-state. CONSTITUTION:A log amplifier 5 gives an exponential characteristic to an output of a phase detector 3 and gives the result to a voltage controlled oscillator 1. Thus, the oscillated frequency of the voltage controlled oscillator 1 changes exponentially to a phase detection output. Thus, even if the time constant of a low pass filter rectifying the output of the phase detector 3 is decreased, since the change in the oscillation frequency with respect to the change in the control voltage at the steady-state is less, the instable oscillated frequency is prevented. On the other hand, in case of out of synchronization, the change in the oscillation frequency is large and a sufficiently large control voltage is produced, the tracking speed, that is, the pull in time characteristic is improved.

Filed: 1985-09-10
Abstract: PURPOSE:To prevent a hangup or time-out error state from being entered by answering to a data transfer request from the opposite device after no-operation data is messaged out. CONSTITUTION:If an initiator 1 confirms that data is messaged out when a data transfer phase is entered after the initiator 1 issues a command, no- operation data which has no meaning is outputted from a no-operation data output circuit 124. Simultaneously, the initiator 1 completes preparations for transition to the data transfer phase, performs the data transfer phase, and moves to next phases successively to confirm that a bus is free. Consequently, acknowledge characters ACK to the request are synchronized securely and a hangup or time-out error state is prevented from occurring.

Title: Drive pipe coupling structure
Inventor: OCHI SYOICHI
IPC: E21D9/06
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To provide a drive pipe coupling structure made of FRPM(fiber reinforced plastics). SOLUTION: Peripheral surfaces of end portions of pipes P opposed to each other are cut. A collar 11 is fitted and attached to a small diameter portion of a pipe P through packing 12 so as to constitute a socket 13. The collar 11 and the pipes P have the same outer diameter to implement smooth driving. An insertion hole 14 of another pipe P is inserted into the socket 13 through packing 15, an end face of the insertion hole 14 is allowed to abut to an end face of the socket 13 through a cushion material 19. The abutting face is against driving force. In the case of the insertion of the small diameter portions (the insertion hole 14 or the like) of the pipes P, a folded projection 17 is easily folded in the insertion direction to allow the insertion and to sufficiently function as a seal.  A semicircular sectional projection 20 differs from the folded projection 17 in that the projection 20 is not inclined but crushed to bend. Accordingly, the collar 11 and the small diameter portions of the pipes P are easily kept being on the same axis. The collar 11 and the pipes P are not susceptible to axial displacement, so that straight-line stability of the collar 11 and the pipes P is kept.

Title: Optical system for correcting light quantity distribution
Inventor: SEKIZAWA HIDEKAZU
IPC: G02B27/18
Filed: 1981-12-15
Abstract: PURPOSE:To adjust a light quantity distribution in a photodetecting optical system, by varying a space filter for intercepting a part of an optical path to the photodetecting optical system from an object to be image-formed, in accordace with the object to be image-formed. CONSTITUTION:A titled system is formed by a uniform illumination 31, an image forming lens 32, a douser 33 which is much smaller than an aperture of the image forming lens 32, an aperture 34, and an image forming surface 35 such as an image pickup tube, etc. When peeping into the uniform illumination from an original point of the image forming surface 35, light from the center part of the uniform illumination 31 is intercepted by the douser 33. Accordingly, at the original point of the image forming surface 35, the quantity of light drops very much. On the other hand, even if the aperture 34 is made to peep at from a point separated from the original point, the douser 33 does not intercept the optical path, therefore, light nearly passes through without stopping, and accordingly, as a whole as for the light quantity distribution on the image forming surface 35 against the uniform illumination, the quantity of light is small in the center part, and in the circumferential part, the quantity of light becomes a large distribution.
