Inventor: TORII AKIRA
IPC: F02D13/02
Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To surely change valve timing without spoiling the sealing of a hydraulic oil chamber. SOLUTION: A vane member 30 is contained in a housing member 18. The housing member 18 is formed with a radially projected projection 28 and a step 54. The vane member 30 is formed with a plurality of radially projected vanes 33 and a step 49.

Title: Facsimile receiver
Inventor: KOSEKI KIYOUJI
IPC: H04N1/40
Filed: 1982-09-28
Abstract: PURPOSE:To attain reproduction without deteriorating picture quality, even for a signal including an intermediate tone level, by discriminating whether or not a demodulated picture signal includes much intermediate tone and adjusting automatically a binary-coded slice level to the black level side when discriminated as including the intermediate tone. CONSTITUTION:A slice section 6 has at least two slice levels, and each level is arranged near a white and a black picture signal level. Thus, in case of a picture signal corresponding to an intermediate color, an L level signal is outputted from a circuit having a slice level sl1 and an H level is outputted from a circuit of sl2. Thus, a gate 7 discriminates whether or not the intermediate tone is included with an output of the slice section 6. An intermediate picture element counter 8 counts the number of picture elements of intermediate tone in one scanning line and gives an output when the number exceeds a prescribed number. An intermediate tone line counter 10 gives an output to change the slice level to a variable slice section 4 when the count value reaches a prescribed value. The variale slice section 4 brings the slice level near both signal level of black and reproduces a picture signal corresponding to gray color as a black picture signal.

Filed: 1989-06-30
Abstract: PURPOSE:To protect a main motor against excessive fault current by arranging a diode for blocking counterflow to an armature coil, upon grounding of the armature winding, between the armature winding and an armature chopper circuit. CONSTITUTION:Upon occurrence of ground fault X on an armature winding 7A1, fault current induced by the counter electromotive force produced during turn OFF interval of a control commutator element THD flows to the ground side thence flows reversely through the voltage withstanding protective diode PD in an armature chopper circuit 10A to the armature windings 7A1, 7A2. The counterflow is blocked by an anti-counterflow diode ISD arranged between the armature chopper circuit 10A and the armature winding 7A2 and the excessive fault current does not flow through the armature windings 7A1, 7A2. Consequently, the armature windings 7A1, 7A2 in a shunt motor are not heated abnormally with the fault current.

IPC: H03M1/20
Filed: 1979-12-28
Abstract: PURPOSE:To realize not only a high speed but a high accuracy for an A/D converter, by combining the main and secondary clock pulses. CONSTITUTION:The main clock pulse given from the main clock generator 4 and having the repetitive frequency fM is applied to the wave crest-time converting circuit 1 to give a synchronous control to the rise of the square wave of the conversion output. Thus the units of the main clock pulses are counted in the form of the rough value of the time duration. On the other hand, the secondary clock generator 5 produces the clock pulse having a relation of [N/(N-1)].fM to the frequency fM to the frequency fM of the main clock pulse. The generator 5 is driven to start the generation of the secondary clock pulse synchronizing with the end of the square wave signal of the circuit 1, i.e., synchronizing with the discontinuation of counting of the main counter 3. The secondary clock pulse is compared with the main clockpulse through the phase comparator 6, the the secondary clock pulses are counted until a coincidence is obtained in the above comparison. As a result, a counting is possible with an accuracy of N times as high as that of only main clock pulse.
