Title: Tape measure
Inventor: MIZUNO ICHIROU
IPC: G01B3/10
Filed: 1983-06-06
Abstract: PURPOSE:To achieve the accuracy enhancement of a strip like tape measure by eliminating disadvantageous inconvenient points, by constituting a measure material from a wire material while pressing the wire material to a drive wheel for driving a display apparatus by a press roller to prevent the slackening of the wire material. CONSTITUTION:When a drawing tool 8 is set to a measuring start point to pull a main body case, the rotation of a drive wheel 5 is transmitted to a dial display device 45 and a counter 48. The numerical value of the counter 48 is set to zero by pushing a reset button in such a state that a wire material is drawn out and the zero position of the meter board 50 of the dial display device 45 is coincided with a pointer 49 to further pull out the wire material. Whenupon, the length from the halfway of an object to be measured to a measuring final point can be measured. Because the wire material 2 is wound around the outer periphery of the drive wheel 5 plural times and the access place of the material 2 is pressed to the outer peripheral surface of the drive wheel 5 by a press roller 42, the drive wheel 5 revolves without generating slip to the wire material and measuring accuracy is enhanced.

IPC: B60T13/573
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To keep a good braking feel even when providing a reaction transmission means having a spring. SOLUTION: The reaction transmission means 33 of a brake booster has a first spring bearing seat 41 and a second spring bearing seat 42 which are provided in such a way as to be capable of being displaced relative to each other, a spring 43 mounted with a predetermined set load between the first and second spring bearing seats, and a stopper member 44 for preventing the first and second spring bearing seats from being spaced apart by a predetermined distance or more. The first spring bearing seat is provided with a viscoelastic means 47 having a hysteresis, and the viscoelastic means is brought into sliding contact with the second spring bearing seat. Therefore when the spring 43 of the reaction transmission means 33 is compressed, a servo ratio increases.  At the same time, since the first and second spring bearing seats make sliding contact with each other via the viscoelastic means 47, the hysteresis is increased by the viscoelastic means 47 within the range in which the servo ratio increases, whereby a braking feel can be enhanced.

IPC: G11B7/09
Filed: 1985-05-13
Abstract: PURPOSE:To attain a control system with a comparatively simple structure and high reliability by using a tracking control system using a carriage performing the closed loop control to secure the follow-up to an eccentric track. CONSTITUTION:The track follow-up control system of a carriage 3 applies a closed loop control system. Then the track follow-up control of the carriage 3 is not carried out based on the track error signal TES used conventionally but by the sine wave produced by a sine wave generating means 12. This sine wave is produced according to the shift degree of an objective lens 10 toward the disk radius direction. The shift degree of the lens 10 is not measured directly but obtained via an equivalent circuit 13. In other words, the lens 10 is shifted by the drive signal given from a lens tracking means 7 based on the signal TES. In this respect, both the means 7 and the circuit 13 of an actuator 9 are used and the signal TES is applied to them. Thus the signal corresponding to the shift degree of the lens 10 is obtained in the form of an output.

Title: Two-component type developer for electrophotography
Inventor: KUBO TSUTOMU
IPC: G03G9/097
Filed: 1983-06-09
Abstract: PURPOSE:To obtain a two-component type developer easy to process, independent of environment, and contg. a toner with high chargeability by using a carrier coated with silicone resin. CONSTITUTION:A two-component type developer is composed of a toner and a carrier, and part or all of the carrier is coated with silicone resin. Since silicone resin has a superior hydrophobic property and superior contamination resistance, the dependency of th toner on environment, especially the moisture resistance is improved, and the initial characteristics can be maintained for a long term. Pure silicone resin has, however, low mechanical strength and an inferior wetting property, so it is modified with acrylic resin or the like to provide resistance to long-term high mechanical stress. Silicone resin or modified silicone resin charges the toner positive or negative and has high charging power, and the toner is electrostatically charged in a short time. When the toner is required to be charged highly negative, silicone resin having introduced amine groups is effectively used.

Abstract: PURPOSE:To enhance an operation rate, and improve ionization efficiency of an ion source by arranging a filament so that the center line is dislocated from the center line of a slit, and forming an inside surface shape of an arc chamber in a rectangular shape. CONSTITUTION:The center line of a tungsten filament 4 is dislocated from the center line of a slit 3, and only a small part of the filament 4 is made to correspond to the slit 3. Thereby, a tendency of an electric field to extremely concentrate on a local part of the filament 4 is reduced, and the consumptive local concentration is reduced, and since leveling of consumption makes progress, the service life can be lengthened. When a replacing frequency of the filament 4 is reduced, an operation rate can be enhanced. When a cross-sectional shape of an inside surface of an arc chamber 1 is formed in a rectangular shape and a thickness is made thinner than usual, since a stroke of a thermoelectron, particularly, an angle of a chamber 1 inside surface from the filament 4 or a stroke of the thermoelectron proceeding to the vicinity can be made longer, ionization efficiency is enhanced, and a beam current can be increased.

Abstract: PURPOSE:To obtain a delay circuit offering ease of control with a load light for a control current by constituting the delay circuit of a current source, a switch and a capacitor in a VTR or a VDP to control the current of the current source. CONSTITUTION:A waveform A indicates a voltage at an input terminal 13 and a waveform B shows a voltage at an output terminal 14. Assuming that the time is just before a time t0 and each switch is thrown in the position as shown in figure (a). The current of the current sources 2, 3 is made equal to each other. The current of the current sources 2, 3 flows through a path comprising a switch 5, a power supply 12, a diode 10 and a switch 6. When the time reaches the time t0 and the voltage at the input terminal 13 changes, switches 4, 5, 6, 7 are thrown conversely and the current of the current sources 2, 3 flows through the switch 4, a capacitor 8 and the switch 7. Thus, the output voltage is also changed in response to the input signal, the zero cross point of the input voltage is retarded to form the zero cross point of the output voltage. That is, the leading edge of the input voltage is delayed from t0 to t1 and the trailing edge also from t3 to t4, respectively.
