Filed: 1994-07-15
Abstract: PURPOSE:To facilitate the assembling work of a clock body by making a window in the side plate or the bottom plate of the exterior frame of a clock and fitting a component cover integrally in the window thereby preventing the cover from sinking or falling. CONSTITUTION:A window 31 is made in the side plate 11 of the exterior frame of a table clock, for example, and a component cover 40 is fitted therein. In this regard, an enlarged recess 33 is made in the peripheral edge of the window 31 so that the inside part of the window 31 is larger than the outside part thereof thus preventing the cover 40 from sinking to the inside. The window 31 is then clamped, at the upper fringe thereof, by a frame part 49 and a protrusion 53 formed at the upper circumferential wall part 41 so that the cover 40 is rotated about the protrusion 53. When the lower circumferential wall part 44 is pushed strongly into the window 31, a micro bulging part 55 abuts against the lower edge of the window 31. The bulging part 55 is then inserted into the inside of the side plate 11 through slight resilient deformation of the cover 40 or the side plate 11 and the cover 40 is fitted in the window 31 to be secured in place. This structure facilitates the assembling work of a clock including the automation thereof.

Title: Production of magnetic recording medium
Inventor: AOKI NOBUYUKI
IPC: G11B5/845
Filed: 1989-06-26
Abstract: PURPOSE:To stably produce an oriented coating film with good orientation by running a substrate coated with the magnetic coating material through a space between at least one pair of magnets disposed to face each other along the traveling direction of the substrate. CONSTITUTION:The substrate 1 coated with the magnetic coating material 2 is run through a space between at least one pair of magnets 3, 3' facing each other with magnetic poles along the traveling direction of the substrate. While the magnetic coating material 2 for the magnetic recording layer is applied on the substrate, high shearing stress is given to the coating material to cause some orientation of plate-type magnetic particles in the coating material. These particles which are priorly oriented to certain degree are further oriented by running the substrate through the space between the magnets, so that the axis of easy magnetization (in the thickness direction of the particle) of the magnetic particle is made parallel to the substrate surface by the stable magnetic field generated by the magnets parallel to the substrate. Thereby, the obtd. recording layer has good intrasurface longitudinal orientation. By this method, magnetic coating film containing oriented particles can be obtained without causing large disturbance of orientation.

Title: Automatic reading method for vehicle discriminating label in production process
Inventor: SONOBE MASATAKA
IPC: B23Q17/24
Filed: 1986-07-10
Abstract: PURPOSE:To make such a proper threshold value that corresponds to size of reflected luminous energy and disturbance luminous one from a vehicle outside plate attainable, by making the threshold value to be preset by a central processing unit higher when the luminous energy around a discriminating label is large enough but lower when it is small, respectively. CONSTITUTION:If a color of a vehicle outside plate 18 is white, it is altered to a white outside plate threshold value THW, a video signal of a discriminating label 40 is made into a binary code, and it is taken into a frame memory part 36, thus reading of a vehicle discriminating number part 44 takes place. At this time, outer size l1 and outer size l2 of a label frame 46 for the discriminating label 40 are measured, whereby the THW is compensated so as to cause l2/l1 to become the preset range a <l2/l1<b. That is to say, if disturbance luminous energy is small, a pickup picture plane comes dark so that the label frame 46 is picked up thickly, but when it is large enough, the pickup picture plane comes bright so that the label frame is picked up thinly, therefore the relation between the disturbance luminous energy and the threshold value comes to be seeable by the value of l2/l1, so that it is set down to a <l2/l1<b, this the threshold value can be set to the proper value to the disturbance luminous energy.

Title: Coin acceptance controller for automatic vending machine
Inventor: HORI SHIGEKI
IPC: G07D5/00
Filed: 1990-06-21
Abstract: PURPOSE:To omit the useless time/labor of users by displaying whether the coins are acceptable or not at a place near a coin slot by means of a pilot lamp. CONSTITUTION:When the coins are acceptable, a lamp relay 12 is energized to turn on a pilot lamp 5. Thus a display panel 17 is illuminated. When the coins are not acceptable, a control part 14 outputs a signal to disenergize the relay 12. Thus the lamp 5 is turned off to darken the panel 17. Therefore the users can restrain themselves from throwing the coins in a coin unacceptable state. Then it is possible to prevent such an inconvenient case where the useless time/labor is required for the users or the thrown coins are never returned owing to the trouble of a coin accepting device.

Title: Probe provided with stylus force measuring function
Inventor: SAKAGUCHI TAKUMI
IPC: G01R31/26
Filed: 1984-08-03
Abstract: PURPOSE:To eliminate variance of stylus force by detecting a direct reading value or its absolute value of stylus force by a probe and adjusting the stylus force at any time. CONSTITUTION:In probing an object to be measured, if the tip of the body 2 of the probe is brought into contact with the object and thrusted, a stylus force transmitting part 3 is pushed up by elastic deformation of the body of the probe 2 and brought into contact with a pressure sensitive element 4 and pressed. At this time, force F1 applied onto the contact face of the element 4 is force received by the tip of the body of the probe 2, i.e. stylus force F, minus force F2 required to push up the stylus force transmitting part 3 to the position of contact face of the element 4. Accordingly, an output from the element 4 corresponds to F-F2, and when F2 is measured beforehand, an absolute value of stylus force F of the probe is obtained by correcting the output. Thus, stylus force can be adjusted accurately, and variance of measured values due to scattering of stylus force can be minimized.
