Title: Production of special shaped tube
Inventor: NAKAMURA MASANOBU
IPC: B21D26/047
Filed: 1994-02-01
Abstract: PURPOSE:To lighten a constituted member by using a round pipe material as a stock and forming the square cross sectional shaped constituted member having a special shaped part in a part. CONSTITUTION:A position 3 for forming the special shaped part in a square cross sectional shaped special shaped tube product is pre-worked so as to form the smaller dismeter than the other position 4 from the round pipe material 2. Successively, the pre-worked round pipe material 2 is bent at the prescribed angle and if necessary, roughly worked to almost the square cross sectional shape by outer pressure, such as pressing, hammering, and this worked material is incorporated into a bulging die to apply the bulging work. The round pipe material 2 integrally formed as a finder by an extruding work, etc., in the axial direction of the outer peripheral surface is used as a stock and can be formed as the same way. By this method, the special shaped tube having the square cross section and the special shaped part at a part is manufactured.

IPC: H03K17/28
Filed: 1984-01-23
Abstract: PURPOSE:To eliminate the fluctuation of a delay time due to the fluctuation of a power supply voltage by connecting the drain and the common side of FET of a timer circuit via a resistor, and applying a voltage rising or descending together with the elapse time to a gate so as to output a current or a voltage change of the drain. CONSTITUTION:The drain D and the common side of a p-channel junction FET26 constituting a timer circuit are connected via a resistor to prevent the source S side of the FET26 from exceeding a desired voltage set by a Zener diode 9. A voltage rising or descending together with the elapse time when a capacitor 25 is changed or discharged is applied to the gate of the FET26. The output from the drain D or the FET26 is fed to a PNP transistor Tr to generate a desired output at a prescribed time after the switch 24 is operated. Moreover, a Zener diode is added to prevent the fluctuation of the value of the capacitor 25, allowing to decrease further the fluctuation of the delay time due to the fluctuation of a power supply voltage.

Title: Oscillation circuit
Inventor: TONAMI MASAHIRO
IPC: H03L1/02
Filed: 1989-01-20
Abstract: PURPOSE:To prevent an oscillation frequency from changing against the change of an environmental temperature or a source voltage by providing an oscillator whose oscillation frequency is provided with characteristic having negative inclination against the change of the environmental temperature and that of the source voltage, and an oscillator with the characteristic having positive inclination. CONSTITUTION:When at least either the environmental temperature or the source voltage VCC changes and the oscillation frequency f1 of the oscillator 1 is increased and simultaneously, the frequency f2 of the oscillator 2 is decreased, a phase comparator 3 outputs a signal of positive level. Next, a power source circuit 4 is operated so as to increase the voltage VCC to be supplied to the oscillators 1 and 2, and when the voltage VCC is increased, the f1 is lowered, and the f2 is raised, then, the frequencies f1 and f2 coincide with the oscillation frequency f0 of an output signal OUT. Also, when the frequency f1 is lowered and the frequency f2 is raised, the comparator 3 outputs a signal of negative level, and the circuit 4 is operated so as to decrease the voltage VCC to be supplied to the oscillators 1 and 2, and the frequency f1 is raised and the frequency f2 is lowered, then, the frequencies f1 and f2 coincide with the frequency f0. In such a way, it is possible to suppress the change of the oscillation frequency against that of the environmental temperature or the source voltage, and to always keep the frequency f0 of the output signal constant.

SO2-containing high temp. gas is introduced into the duct 9 and cooled by the H2O2 solution. The gas, from which SO2 is recovered to a certain degree through the reaction with H2O2 in the duct 9, is further reacted with the H2O2 solution in the packed tower 1 and recovered as sulfuric acid. The residual gas, from which SO2 is recovered, is discharged out of the system through a mist separator 3.

Title: Warning detection system for loop type data transmitter
Inventor: TAKATSUKA SAWAKO
IPC: H04L12/42
Filed: 1989-01-23
Abstract: PURPOSE:To accurately detect the abnormality of each slave station by sending a zero bit as a bit for warning detection when a master station sends data, and adding a specific number to the bit and sending the sum when each slave station receives them normally. CONSTITUTION:When the master station MS sends data to the respective slave stations SS1-SSN, a U/D bit indicating whether the data are sent upward or downward is used as the bit for warning detection and 0 is sent as the bit. The slave station SS1 which receives the bit normally adds 1 as the specific number to the bit and sends the sum to the slave station SS2, which receives it similarly, further adds 1 to the bit, and sends the result as 2 to the next slave station SS3. Thus, the following slave stations SS3-SSN adds 1 to the bit and sends the result as long as the data can be received normally. The master station MS judges that some slave station enters an abnormal reception state unless the value of the U/D bits is N, thereby detecting communication abnormality.
