Title: Welding method of ring chain
Inventor: MIZUMOTO YOSHIHIRO
IPC: B23K9/038
Filed: 1982-09-27
Abstract: PURPOSE:To reduce man-hour without generating any node in a weld zone without requiring powerful mechanical pressure by pressing pressing bodies to both ends of a chain ring, and moving a pair of arc welding torches from the inside to the outside of the butt ends of wires. CONSTITUTION:A chain connected with chain rings is set on a working table 1 having inclined guide parts 2 on both sides, and a chain ring A to be worked is erected and held on the table. The butt ends B of the wires are positioned upward and suitable holding rods are advanced simultaneously from the side of the chain ring to stabilize the upright attitude. The table 1 is then moved upward to press a pair of pressing bodies 4 to the curved parts C at both ends of the chain rings. Welding is performed by generating an arc between torches 5 and the butt ends of the wires; in this case, the torches 5 are put in the down position and the welding is started from the inside of the ring A to be worked, that is, the lower side of the butt ends B. Both sides of the butt ends B are subjected to overhead welding simultaneously while the torches 5 are gradually moved upward.

When the pigment is used as a coloring agent, beside the pigment itself is dispersed as a component insoluble in water, it is used by combining to other component insoluble in water. As other component insoluble in water than the coloring agent, a resin component having hydrophilic group and hydrophobic group is used. The nozzle orifice of the record head is processed with water repellent treatment. For the water repellent treatment, various processing techniques are utilized in accordance with purposes such as coating and eutectoid plating. When the nozzle orifice is processed with the water repellent treatment, the solidified ink can be entirely discharged by cleaning without sticking to the nozzle orifice at all.

IPC: B41J2/49
Filed: 1982-09-29
Abstract: PURPOSE:To prevent the occurrence of print errors with a simple construction without the need for a complicated auxiliary device, by effecting double printing when a pen printer suspends its printing operation and a predetermined period of time has elapsed.

In the case where the CPU21 receives the time-up signal from the timer 25 during the period from the time when it delivers the set signal to the timer 25 until the time when the CPU21 receives CR, LF or other code from the outside or when the CPU21 internally generates a print start command, the CPU21 generates an interrupt command, thereby to control a trial printing operation for preventing the ink on the point of a pen 3 from becoming dry.

Title: Substrate for mounting semiconductor chip
Inventor: KIRA TOSHIHIKO
IPC: H01L23/14
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To reduce the strain at the junction interface to hold good radiation characteristics, by adding ceramics or metal grains having a less thermal expansion to Cu. SOLUTION: A substrate is composed of at least two plates having different thermal expansion coefficients i.e., a sintered plate composed of Cu or Cu alloy grains 20-70 vol.% and at least one kind of grains selected among ceramics and metals having smaller thermal expansion coefficients than that of Cu and ceramic plate. The metal is selected among Mo, W and Si. This reduces the thermal expansion coefficient difference between the ceramics and the metal for the metal substrate, and hence reduces the strain at the junction interface to hold good radiation characteristics.

Title: Vibration control device
Inventor: HAMADA MASAAKI
IPC: F16F15/02
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To obtain the low dynamic spring characteristic over a wide frequency zone while ensuring the static spring rigidity by contacting and supporting a mass member displaceable independently from a member on a vibration transmission passage, by self-weight of the mass member through an elastic supporting member. SOLUTION: When the frequency of input vibration is low, a mass member 42 is oscillated with frequency same as that of the first and second fittings 12, 14 and a main body rubber elastic body 16, and the mass member 24 is integrally displaced while being nearly in contact with a tapered inner peripheral surface 32 of the elastic body 16. When the frequency is close to the natural frequency determined on the basis of the mass of the mass member 42 and the supporting spring of the mass member 42 by the elastic body 16, the mass member 42 is brought into a resonant condition, its amplitude is increased, and the mass member 42 is separated from the elastic body 16 and vibrated. As a result, a phase of the mass member 42 is displaced by about 180 degrees with respect to the elastic body 16, and the mass member is repeatedly contact brought into with the inner peripheral surface 32.  Whereby the vibrational displacement and the energy of the elastic body 16 are compensated by those of the mass member 42, the dynamic spring constant of the elastic body 16 is reduced, and the vibration proof performance can be improved.

Filed: 1986-07-18
Abstract: PURPOSE:To attain the smooth progress of conference without time lag by driving and controlling a transmission cut-off circuit and a reception cut-off circuit based on the result of comparison between outputs of transmission/reception power level detection circuits. CONSTITUTION:In case of the transmission by a subscriber 10 and of the reception by subscribers 11, 12, an output of a transmitter 1 is inputted to a transmission power level detection circuit 3, its output exists and inputted to a comaprator circuit 5. Farther, the output of a reception power level detection circuit 4 is zero and given to the circuit 5.

On the other hand, the reception signal is transmitted at the side of subscribers 11, 12 and the transmission signal is interrupted. Satellite ground station equipments 30-32 are provided with OR circuits 40-42 to integrate reverse channels for multiple address communication into one with respect to down-channels 60-62, and since a signal from subscribers not in communication through the down-channels is always 00000000, only a signal of the down- channel for the subscriber in communication is sent to each subscriber.

Title: Radiation pileup detecting circuit
Inventor: KISHI HARUO
IPC: G01T1/164
Filed: 1989-06-30
Abstract: PURPOSE:To detect a pileup which occurs from a rise to a peak by providing a means which holds the peak value of an input signal from a radiation detector and a means which compares this signal with an original input signal at specific timing. CONSTITUTION:The input signal S1 from the radiation detector is led to a peak holding circuit 1 and passed through an attenuator 2 to supply a peak hold signal S2 to a comparator 3. The signal S2 is compared by the comparator 3 with the original signal S1 and the comparator 3 generates an output S3 rising when the signal S1 becomes larger than the signal S2. Therefore, it is judged from the output S3 of the comparator 3 that the input signal reaches the peak. The state of the output S3 is judged by a timer circuit 4 after the timing of a constant time T behind the input signal. If a pileup occurs before the input signal rises, the time from the rise to the peak becomes long, so the signal does not reach the peak at the timing T and the signal S2 is smaller than the signal S1, so the output of the comparator 3 is Low and the output of the timer 4 is therefore Low, thereby detecting the pileup.

Title: Transmission control system

IPC: H04L29/08
Filed: 1990-06-27
Abstract: PURPOSE:To allow a data communication processing section to detect the end of data transmission by recognizing it that the data transmission is finished when an actual transmission time is a calculated transmission time or over, transmitting and receiving a succeeding data to a data transmission circuit section. CONSTITUTION:A data transmission request reception command means 11a sends a data to a destination via a data transmission circuit section 13 when the data is not sent on the occurrence of a data transmission request and a data transmission time arithmetic means 11b calculates a data transmission time Tc based on a transmission data length and a data transmission speed. Then a data transmission end monitor means 11c calculates an actual transmission time (t) to monitor whether or not the time reaches the data transmission time Tc or over and in the case of t>=Tc, it is taken that the data transmission is finished. Thus, even when no data transmission end notice comes from a data transmission circuit block 13, the data communication processing section 11 detects the end of data transmission internally.
