Abstract: Disclosed is a chronograph timepiece in which it is possible to prevent the chronograph drive timing and the magnetic field detection timing from overlapping each other to unnecessarily effect driving with correction drive pulses. A processing unit controls drive circuits so as to drive a time indication motor and a chronograph indication motor with a predetermined timing based respectively on timekeeping information obtained and chronograph measurement information obtained, and effects control such that a magnetic field detecting unit detects a magnetic field with a predetermined timing; when the drive timing for the chronograph indication motor and the magnetic field detection timing for the magnetic field detecting unit overlap each other, the processing unit changes the magnetic field detection timing for the magnetic field detecting unit so that the drive timing for the chronograph indication motor and the magnetic field detection timing for the magnetic field detecting unit may not overlap each other.
Abstract: A bearing unit has four rolling bearings adjacently disposed in an axial direction, each rolling bearing including an inner race, and outer race, and rolling elements interposed between the inner and outer races. A shaft is fitted to the inner races, and a sleeve has a fitting hole into which is fitted the outer races. The inner races or the outer races are brought into contract with each other in the axial direction to preload the rolling bearings. The inner races or the outer races of the rolling bearings at both axial ends, which are brought into contact with the inner races or the outer races of adjacent rolling bearings, are fixed to the sleeve, and the outer races of the central two rolling bearings form a radial gap between confronting surfaces of the sleeve and the outer races or between confronting surfaces of the shaft and the inner surfaces.
Abstract: To print an excellent image formed without distortion or image failure by mitigating irregularities, inclination, or the like of an installation floor surface. In an ink jet recording apparatus including an ink jet recording apparatus main body and a leg portion, a deformation absorbing member is interposed in a joint portion between the ink jet recording apparatus main body and the leg portion. Therefore, even if there are the irregularities, the inclination, or the like on a floor surface to which the ink jet recording apparatus is installed, it is possible to ensure leveling of a print surface in the ink jet recording apparatus main body, thereby being capable of obtaining the excellent image without the distortion or the image failure.

The quartz crystal resonator comprises a quartz crystal tuning fork resonator capable of vibrating in a flexural mode of an inverse phase and having at least one groove, and an electrode is disposed on at least one of opposite side surfaces of each of the first and second quartz crystal tuning fork tines. The quartz crystal tuning fork resonator has a capacitance ratio r2 of a second overtone mode of vibration greater than 1500. The lid is connected to the case through a connecting member to cover the open end of the case.
Abstract: When it is judged that a chronograph second counter and a chronograph minute counter have measured a maximum measurement time, a maximum measurement control unit controls a drive pulse generation circuit so as to drive and stop a motor such that chronograph hand stops at predetermined positions. When, in this state, a restarting operation is performed on a start/stop button, a normal chronograph measurement operation is restarted. At this time, a mechanical structure has been restored to a reset state, so that even at the time of restarting after the measurement of the maximum measurement time, the load at the starting operation is the same as that of the normal operation, thus generating no sense of incongruity.
Abstract: Disclosed is a chronograph timepiece in which it is possible to prevent a non-rotation state at the time of first driving when chronograph measuring operation is reset during motor drive and restarting is effected. When a resetting operation is performed on a reset button during the driving of a motor and a rotation detection circuit detects non-rotation, a drive control unit controls a drive pulse generation circuit such that the control is completed without reversing the polarity of a motor drive pulse output from the drive pulse generation circuit, and that the motor is driven by a drive pulse of the same polarity as that at the time of the previous resetting in response to a starting operation performed on a start/stop button, driving the motor by the drive pulse of the same polarity at the time of restarting after the resetting.

Abstract: A cutting apparatus cuts a lateral wall of a manhole to form a hole on the lateral wall of the manhole. A circular pipe is harmonized with a main pipe and fixedly disposed therein. A rotary ring configured so as to be able to rotate along the periphery of an opening in the manhole about the axial center of the main pipe is mounted on the circular pipe. A pressurized fluid material or pressurized granular material is sprayed from a nozzle held in the rotary ring. The rotary ring is rotated and the lateral wall of the manhole is cut through along the periphery of the opening in the manhole by the fluid material or granular material sprayed from the nozzle. Since the cut portion is shaped as a circle symmetrical about the axial center of the main pipe, it is possible to form a circularly shaped cut-through part centered along the periphery of the opening in the manhole without accidentally breaking or damaging the lateral wall thereof.
Abstract: A liquid jet recording apparatus adjusts the pressure of liquid jetted from a jetting portion toward a recording medium. The liquid jet recording apparatus has a pressure sensor provided in a tube between a liquid storing portion and a roller tube pump. The pressure of the liquid which flows through the tube is measured, and a pressure value is sent to a control portion. The pressure value is compared with lower limit values and upper limit values stored in a definition file stored in the control portion, and a corresponding drive signal is sent to a drive portion to drive the roller tube pump in a forward or a reverse direction to adjust the pressure of the liquid in the jetting portion.
