Title: Indicating instrument
Inventor: OIKE YUKIO
IPC: H02P8/00
Filed: 1992-07-14
Abstract: PURPOSE:To provide an indicating instrument having a needle rotation detecting section. CONSTITUTION:An indicating instrument is an analog-type speedometer 2, and uses a stepping motor 12 as a drive source. A motor driving circuit 13 is connected to the motor 12. Based on a pulse signal from a control circuit 10, the motor driving circuit 13 operates to rotate the motor 12 to cause an indication by the needle 11. When the motor 12 rotates based on the pulse signal, a waveform of a current flowing through a coil of the motor 12 assumes a rectangular wave that corresponds to a waveform of an input pulse signal, and has peaks at shoulders. These peaks are extracted by a clipping circuit 15 and input to a detection circuit 16. Based on a resulting detection signal, it is judged whether the motor 12 is rotating correctly.

Title: Water shielding method for side slope with earth lining
Inventor: NAGANO HIROO
IPC: E02D17/20
Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To improve water shielding with works executed efficently and safely by a method wherein consolidation and compaction are applied to cohesive soil sprayed into the inside of a side slope form with water absorptivity of a polymeric material arranged in the form and a shrinking body having shrinkability deriving from its shape utilized, and a lining layer formed of the cohesive soil is formed integrally on the side slope. SOLUTION: Forms are fixed on the surface of a side slope on which water shielding is to be applied, and the side slope is demarcated with a latticelike side slope frame. A linear shrinking body 1 made of a polymeric material developing high shrinkability with water absorbed is arranged in the demarcated side slope frame so that the direction of shrinkage can be turned to the normal of the side slope, and furthermore in a shape of corrugation. Then, a spraying material made by kneading cohesive soil with water added is sprayed into the inside of the side slope frame. The linear shrinking body 1, with water in the spraying material absorbed, shrinks gradually and compresses, during its process of shrinkage, the spraying material, namely a lining material.  Furthermore, the linear shrinking body swells in the direction of tangential line of the side slope in proportion to the Poisson's ratio, working in compaction in the tangential line of the side slope, and thereby a lining layer is formed.

Title: Paper feed mechanism in printer
Inventor: INOMATA MITSUGI
IPC: B41J11/00
Filed: 1989-07-21
Abstract: PURPOSE:To reduce the number of feed rollers and to properly conduct the forward and reverse feed of any of continuous paper and cutform without generating a slack by a method wherein supply-side feed rollers can be driven forward and reverse and separated from each other, discharge-side feed rollers can be driven forward and idled reverse, and the paper feed force of the supply- side feed rollers is made larger than that of the discharge-side feed rollers. CONSTITUTION:When a cutform is fed, the cutform is fed between discharge-side feed rollers beta and supply-side feed rollers alpha. Since the discharge-side feed rollers betaoverfeed the cutform with a paper feed force smaller than that of the supply- side feed rollers alpha, the cutform is applied with a tension while slipping at the discharge-side feed rollers beta and constantly fed by the supply-side feed rollers alpha. At the time of reverse line feed, the drive of the discharge-side feed rollers betais stopped, and the supply-side feed rollers alpha are reversely rotated by a predetermined number of rotation. In this manner, the cutform is returned to a predetermined position by the supply-side feed rollers alpha while being lightly braked by the idling of the discharge-side feed rollers beta. Therefore, since the cutform is applied with a reverse tension caused by the idling of the rollers, the occurrence of misregistering and slacking is eliminated.

Title: Overlap record preventing system for optical recording and reproducing device
Inventor: SUZUKI MOTOYUKI
IPC: G11B7/00
Filed: 1984-09-10
Abstract: PURPOSE:To prevent the overlap record to a recorded track by discontinuing a recording action of information when it is detected that the intensity of the reflected light changes at a level higher than the reference value in a mode when the information is recorded by projecting laser light to a medium. CONSTITUTION:The light beam sent from a laser diode 28 is turned into parallel beams through a collimator lens 29 and then stopped down on a disk in the form of a spot by an objective lens 33 attached to an actuator 32 through a polarized beam splitter 30 and a 1/4-wavelength plate 31. The reflected light sent from the disk 1 is reflected again by the splitter 30 and divided into two parts by a mirror 35 after passing through a convex lens 34. One of these two divided beams is made incident on a 2-split photodetecting element 37 which detects a focus error through a concave lens 36. While the other beam is made incident on a 2-split photodetecting element 38 which detects a tracking error. The sum voltage of four outputs in all of both elements 37 and 38 is defined as the standard value. Then a recording action of information is discontinued when it is detected that the intensity of the reflected light varies at a level higher than said standard value. Thus the overlap record can be avoided to a recording track.
