Title: Recording method
Inventor: NISHIMURA TAKASHI
IPC: G03G15/32
Filed: 1983-02-08
Abstract: PURPOSE:To improve expressing performance for half-tone and to perform half- tone recording with fidelity by controlling the diameter of a laser beam spot on the surface of a photosensitive body to record in responding to the density with which the recording is performed. CONSTITUTION:A filter 13 having an increasing transmitance rate toward the center part is installed between a laser diode 11 and a rotary polygon mirror 14, and the intensity of a laser beam outputted by the laser diode 11 is converted into a beam having the distribution corresponding to the density signal of recording information. This beam is reflected by the rotary polygon mirror 14 to scan on the photosensitive body 16 through an Ftheta lens 15, writing the recording information. Only a beam with light intensity larger than a specific slice level Lth operates effectively on the photosensitive body 16, so beam spots with different diameters corresponding to the light intensity distribution, e.g. B1-B3 are formed.

Title: Combining shaft pin
Inventor: OKUBO HISAMITSU
IPC: F16B19/02
Filed: 1994-02-15
Abstract: PURPOSE:To provide a combining shaft pin of which elasticity of the shaft part in a forked part supporting the head part can be freely set without having an extremely bad effect on rigidity of the whole pin. CONSTITUTION:In the structure of a combining shaft pin provided with a trunk part (shaft part) 1, and a head part 2 which is integratedly provided on one end of the trunk part 1, formed into larger diameter than that of the trunk part 1 at the nearby part to the trunk part 1, and decreases the diameter with going away from the trunk part 1 so as to be formed into smaller diameter than that of the trunk part 1 at the end, the part positions of respective grooves 5a, 5b near by the head part 2 are gradually digged down deep with approaching the head part 2 for further improving elasticity of a forked part provided with a slot groove 4.

Title: Zero point compensation circuit of pressure transducer
Inventor: YANADA TAKASHI
IPC: G01L1/22
Filed: 1987-01-30
Abstract: PURPOSE:To prevent the deviation of zero point voltage due to the change in the circumferential temp. of the preliminarily adjusted output of an amplifying circuit, by utilizing the bridge circuit of a semiconductive resistor as a pressure sensor and a temp. sensor and directly applying potential divided by an external resistor to the amplifying circuit as voltage to be supplied. CONSTITUTION:The constitutional element of a pressure sensor 1 is a semiconductor and, therefore, said element is high in temp. coefficient and increases the shift of zero point voltage after adjustment when the circumferential temp. largely changes. Since the zero point voltage Vo in the output voltage of an amplifying circuit 15 is adjusted, voltage Va is given by voltage dividing resistors 11, 12. When circumferential temp. change is t deg.C, the offset voltage of the pressure sensor 1 is Voff and the gain of an amplifier 10 is Ga, the temp. coefficient of the semiconductor is set to alphaand Vo(t)=Va(1+alphat)-Ga.Voff(1+alphat) is formed and the shift from the zero point voltage Vo becomes Vo.alphat. Therefore, Vo may be made low. In this constitution, the voltage of a constant current power source is directly given to the amplifying circuit in a divided form and the zero point voltage secondarily generated in the sensor by the change in the circumferential temp. is reduced and, therefore, when the mu-factor of the amplifying circuit is especially high, the deviation from an adjustment point can be reduced.

CONSTITUTION:A slip-frequency instruction omegas, a magnetic-flux-component current instruction i1d* and a torque-component current instrucction i1q* are output to a circuit 100 by constituent elements denoted by symbols 25 to 36 on the basis of a secondary magnetic-flux instruction PHI2* and a torque instruction T*, and the primary current of an induction motor 23 is controlled. In this case, the omegas, i1d* and i1q* are operated by the following equations: omegas=R2*/PHI2*<2>XT*, i1d*=dPHI2*/dt/R2*+(PHI2 +dPHI2*/dt/R2*X12*)/M* and i1q*=T*/PHI2*+(T*/PHI2*-m12*)/M*. Consequently, even when the mutual inductance of the induction motor is changed, it is possible to offset the influence of its magnetic saturation when the factor 1/M* of factor devices 29, 35 is used as a magnetic saturation function given by a gap magnetic flux.
