Title: Production of orientation-controlled steel strip
Inventor: KOHO HIROSHI
IPC: C21D8/12
Filed: 1989-12-08
Abstract: PURPOSE:To form a steel strip into a crystal of prescribed orientation by means of strict control by joining a seed material having prescribed crystal orientation in a low-energy state to a coiled steel strip as a material to be treated while forming respective joining planes into activated state and then allowing boundary migration to occur by means of heating. CONSTITUTION:A coiled steel strip is used as a material to be treated. A seed material having a crystalline structure equal or similar to that of the above material and also having prescribed crystal orientation in low-energy state is brought into contact with the spiral edge of the above coiled steel strip while forming respective joining planes into activated state to undergo joining. Then, heating is carried out to allow boundary migration to occur and the coiled steel strip is formed into a crystal of prescribed crystal orientation. At the time of joining, if an insert material having a melting point lower than those of the seed material and the material to be treated is interposed between the above materials, joining can be easily attained in a practical inert gas. By this method, crystal orientation can be strictly controlled and industrial mass production is made possible.

Filed: 1990-11-26
Abstract: PURPOSE:To accurately carry out the fatigue test of a test piece in corrosive environment by supplying the corrosive medium adjusted to predetermined temp. in a thermostatic tank to a corrosion tank. CONSTITUTION:The corrosive medium 12 adjusted to predetermined temp. within a thermostatic tank 1 naturally flows down from a supply port 6 to reach the water supply port 31 of a corrosion tank 3 to be guided to the corrosion tank 3. The medium 12 guided to the corrosion tank 3 is used in the corrosion of the test regions 4a of a test piece 4 and subsequently overflows from an overflow port 32 and naturally flows down to be quided into a storage tank 2 from the water supply port 9 of the storage tank 2. The corrosive medium 12 once stored in the storage tank 2 is taken out of a drain port 10 to be circulated to the thermostatic tank 1 from the water supply port 8 thereof by a circulating pump 5 to be adjusted to predetermined temp. The medium 12 flowing out of the overflow port 7 of the thermostatic tank 1 is also stored in the storage tank 2 and recirculated to the thermostatic tank 1 by the pump 5 and, therefore, the medium 12 does not flow out of the tank during the test.

Filed: 1999-11-09
Abstract: PROBLEM TO BE SOLVED: To prevent the noise of a compressor and reduce the up/down temperature deviation in heating by limiting a frequency reduced by a specific value, from the current operating frequency of the compressor to the maximum frequency and hence decreasing the count of rise/fall of the compressor operating frequency when heating overload conditions have been detected.

In this case, it is judged whether the temperature of the indoor heat exchanger has increased above a fall temperature due to the heating overload conditions or not.  Then, when the judgment result is YES, a frequency obtained by decreasing the operating frequency before the fall temperature by a specific frequency e.g. 2 Hz is set to be a maximum frequency of the compressor 13, and when the temperature of the indoor heat exchanger has decreased below a released temperature, and it is judged that it has taken a required time for the fall, a frequency obtained by increasing the frequency by a specific frequency from the limitation maximum frequency is set to be a maximum frequency again.

IPC: H04L7/00
Filed: 1989-12-08
Abstract: PURPOSE:To early detect a fault by counting the number of received data invalid codes when a synchronizing fault occurs at the received data and shifting automatically the operation to a synchronization detecting mode when the counted number of invalid codes exceeds a fixed level. CONSTITUTION:When a synchronizing fault occurs at the received data and a reception circuit (a) becomes idle, the invalid codes are written into a reception buffer 3 in a synchronous circuit 2. Then a comparator 5 detects continuously the invalid codes and the value (n) of a counter 7 increases. When a comparator 8 decides the coincidence between the prescribed invalid code continuous reception allowing frequency (p) and the counter value (n), an invalid code reception interruption signal (s) is outputted to an external circuit. The counter 7 is cleared by the signal (s) and a synchronization detecting instruction signal (d) is inputted to the circuit 2 from the external circuit. Then the operation is shifted to a synchronization detecting mode.
