Filed: 1982-03-03
Abstract: PURPOSE:To eliminate the need for the delay of a super input signal in many bits in inserting the super input signal as the super and without shift in the position of the super input signal down right, even if a wider shadow is generated, by generating the shadow with the field loop. CONSTITUTION:The level of the super input signal applied to an input terminal 1 is compared with that of a shadow key signal being a field feedback signal at an NAM circuit 2, the higher level is selected and outputted to a level control circuit 3 and a shadow key signal conversion circuit 6. The level control circuit 3 performs the level control of the field feedback circuit and makes the gain as <=1. The shadow key signal level-controlled is widened by upper and lower one line each vertically at a shadow key generating circuit 5 and by left and right for about one line each horizontally. The width of the shadow key signal is widened by controlling the field feedback gain, and only key signals exist in the field loop, then 4-bit is enough, allowing to obtain a wider shadow key signal with a smaller circuit constitution than conventional systems.

Abstract: PURPOSE:To make it possible to operate a power converter with higher circuit voltage by connecting positive and negative side switch units, respectively, with reactors and eliminating mutual interference between positive and negative side arms at the time of commutation thereby lowering voltage to be applied on a reverse blocking self-extinguishing element. CONSTITUTION:Prior to commutation from phase U to phase V, phase U current is shunted to a series circuit of a GTO 6 and a diode 18 and a series circuit of a diode 19 and a GTO 7.

Title: Manufacture of watch component
Inventor: SHOJI SETSUO
IPC: C22C38/00
Filed: 1994-03-03
Abstract: PURPOSE:To obtain a good mirror surface which is nearly equal to that by austenite based stainless steel by a method wherein ferrite based stainless steel is hot worked in a specific temperature region. CONSTITUTION:Ferrite based stainless steel which contains 0.07 to 0.15% of S, 0.3 to 0.9% of Si and 0.20 to 0.45% of Mn is used, and it is hot worked in a temperature region of 700 deg.C or higher. When its working temperature exceeds 700 deg.C, its deformation stress is not increased even when its deformation amount is increased. In such a state, no strain is accumulated in a component, and a ridge which is peculiar to the ferrite based stainless steel is not generated. Consequently, it is possible to obtain a mirror surface whose strain is small as compared with that by the mirror finishing operation of a cold-worked product. In addition, a mirror surface is obtained by ferrite based stainless steel which contains a free cutting component, and a crack can be prevented.

IPC: G05D23/19
Filed: 1983-03-04
Abstract: PURPOSE:To shorten a temperature rise time and to perform accurate temperature control by controlling the output of the microwave oscillator of a microwave baking device by pulse-amplitude modulation before a body to be dried attains to specific temperature and then by pulse-width modulation thereafter. CONSTITUTION:When the output signal V1 of a temperature sensor 2 rises in voltage level, the voltage difference between a temperature specifying voltage V2 and a signal voltage V1 decreases. Consequently, the output voltage V0 of a proportional plus integral plus derivative PID circuit drops in voltage level and the output W of a microwave Mf also decreases gradually. When V1=V2, movable contacts of switches S1 and S2 are switched from solid lines to dotted lines. Then, the signal V0 of the circuit 1 and the saw-tooth wave signal f1 of the oscillator are applied to a comparator 7 and a pulse output Pc' is sent from the circuit 7 to the microwave oscillator 11, which supplies constant-output electric power which varies in time width with the duty ratio of the pulse output Pc' to the body to be dried.
