Title: Saw-tooth wave generating circuit for oscilloscope
Inventor: SUZUKI TATSUMI
IPC: H03K4/501
Filed: 1985-10-31
Abstract: PURPOSE:To suppress a variation in a sweep start voltage due to the switching of a sweep time by detecting the variation in the output current level of a constant current circuit. CONSTITUTION:When a sweep gate signal is supplied to an input terminal 1, a selected capacitor among C1-C3 is charged in this low-level period and reset in a high-level period. Further, switches S1-S3 are switched to vary the constant current level supplied from the constant current circuit 3, so that the sweep time varies. When the constant current level is switched, the current flowing through a transistor (TR) Q2 also varies, so a correcting signal for canceling this voltage variation is generated an added to a saw-tooth signal. Then, a voltage corresponding to the collector voltage of the TR Q2 is inverted by an operational amplifier 8 and added to the saw-tooth signal of an output line 6, so that the saw-tooth wave signal obtained by subtracting the correction component from the saw-tooth wave signal before the correction is obtained. Namely, the sweep start voltage does not vary even when the sweep time is varied.

Title: Differential transmitter
Inventor: OTANI KEIZO
IPC: G01L13/06
Filed: 1990-09-18
Abstract: PURPOSE:To correctly know accuracy of a transmitter on a control side and also enable appropriate monitoring by time-dividing transmission time and transmitting information on a system error and a fluctuation of the transmitter. CONSTITUTION:A transmission path is time-divided wherein a process value is transmitted on a time slot T1 while a system error determined by static pressure and temperature is transmitted on a subsequent time slot T2. A fluctuation is transmitted on a subsequent time slot T3. In this case the system error is known on a transmission side, while the fluctuation is determined by performance of an A/D-converter and known on the transmission side. Thus by transmitting not only the process value but also the system error and the fluctuation to a control side, accuracy of a transmitter can be known, thereby enabling more appropriate control and monitoring.

Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To provide an electrode superior in a cycle characteristic by passing a composition containing a hydrogen storage alloy between multiple rolls having different revolving speeds, so as to dispersedly knead the hydrogen storage alloy in a paste. SOLUTION: When a binder, a thickener, and a conductive material are mixed to a paste 3, an electrode having superior characteristic can be preferably manufactured. When the paste 3 is passed several times between three rolls having different revolving speeds, alloy grains are dispersed uniformly, the coating property of the surface is improved, and the viscosity of the paste 3 is reduced. The paste 3 having a viscosity of about 4/5 or below of the initial viscosity by this method is used for manufacturing a negative electrode hydrogen storage alloy electrode for a nickel-hydrogen storage battery, thereby the cycle characteristic is improved. The paste 3 is filled into coating heads 2a, 2b and is applied to a punching metal core material 1, while being applied with vibration by vibration exciters 5a, 5b.  The viscosity of the paste 3 is reduced by the vibration of the coating heads 2a, 2b and a uniform coating is applied. The vibration frequency is preferably set to 1-300 Hz.

Title: Decoding method for picture data
Inventor: SHIKAKURA AKISUKE
IPC: H04N19/89
Filed: 1993-09-07
Abstract: PURPOSE:To prevent deterioration in picture quality of a reproduced picture even when a correction disable error takes place by using received motion information as it is to process decoding after a coding data part applied with motion information is revised when a correction disable error takes only in the coding data part. CONSTITUTION:A digital picture signal is coded by a coding circuit 305 to compress the information quantity. The circuit 305 makes compensation prediction coding to generate motion mode information, motion information including a motion vector and coded data.

A memory section 311 of a receiver side stores once the received data string via the transmission line 309 and a correction section 313 corrects a code error. The motion information and the coded data outputted from the memory section 311 are subject to inverse processing to that of the circuit 305 at a decoding circuit 315, that is, the information is expanded to restore the information into original digital picture. The picture signal is outputted from an output terminal 319 via a D/A converter 317.

Title: Electrically weldable sleeve for joining thermoplastic synthetic resin duct section
Inventor: ERUNSUTO REEDE
IPC: B29C65/34
Filed: 1985-11-05
Abstract: The electrically weldable sleeve has a tubular sleeve member, heating elements arranged on the inner wall of the sleeve member and terminals for an energy supply. A material recess in the form of slots is provided in the edge zone of the boundary area of the heating element. This makes it possible to completely utilize the shrinkage reserve imparted to the sleeve member during the production of the sleeve, so that it is effective up to the solidification of the core of the melting zone. It also completely compensates for the volume contraction of the material linked with the solidification of the melting zone, so that the occurrence of cavities is reliably avoided. Corresponding to the axial flux of force represented by lines, the material recesses must be located at a point, which leads to no weakening of the sleeve member portions decisive for assembly and operation.

Title: Signal synchronizing method for token passing bus system network
Inventor: MAEDA TAKAFUMI
IPC: H04L12/28
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To shorten processing time in the case of new subscription for a network and to enable the prediction of a required time by receiving broadcast frames from a master station and synchronizing a timing clock at the present station with that of the master station with that timing. SOLUTION: A CPU 3 sends a start signal 19 to a master station frame extracting part 5 and sends the same synchronizing timing 13 as the network to an internal timing generating part 7. Besides, a clock 8 sends an internal clock 15 to the generating part 7. That clock is synchronized by fine adjustment at the generating part 7. The CPU 3 monitors phase deviation width 14 of the output from the generating part 7 and when that width becomes within a certain value, a command for turning operating mode setting 17 into IN-RING is outputted to a transmission LSI 4. Then, the LSI 4 is subscribed to the network and becomes the member of token passing bus.  Thus, before the station is subscribed to the network, the same timing of the network is synchronized with the timing inside the present station so that the time of out-of-synchronism can be shortened even at the station newly subscribed to the network as well and that time can be specified.
