Inventor: MIURA SHINSUKE
IPC: H04R17/04
Filed: 1983-12-02
Abstract: PURPOSE:To suppress securely a pyro electrical output and to obtain piezo electrical type oscillation pickup which can detect accurately the oscillation ranging from very small oscillation to large oscillation widely by placing a mass body between facing surfaces of a pair of piezoelectric elements.

Title: Method and device for rolling strip
Inventor: UIRUFURIITO BARUTO
IPC: B21B31/18
Filed: 1983-12-06
Abstract: A roll stand has a frame, a pair of small-diameter and substantially parallel working rolls defining a workpiece nip, and respective journal blocks supporting the working rolls in the frame for rotation about substantially parallel axes flanking the nip. These working-roll journal blocks and the respective working rolls can be axially shifted in the frame and the working rolls can be bent positively and negatively, that is respectively convex and concave toward the workpiece. A pair of large-diameter and substantially parallel backup rolls flank and bear toward the nip on the working rolls. Respective journal blocks support the backup rolls in the frame for rotation about substantially parallel axes flanking and generally coplanar with the working-roll axes. A strip is passed repeatedly in a multipass run through the nip generally perpendicular to the plane while the working rolls are pressed against the workpiece to reduce its thickness. The working rolls are axially displaced relative to the workpiece a plurality of times during the run to change the region of contact between the workpiece edges and the working rolls during the run. The working rolls are also bent at least to maintain the workpiece thickness downstream of the nip generally uniform.

Title: Coin guiding apparatus of coin packing machine
Inventor: INOUE MITSUYOSHI
IPC: B65B35/12
Filed: 1987-09-11
Abstract: PURPOSE:To simplify the structure of adjusting the width of a coin guiding portion by the provision of a mechanism for driving a movable side wall so as to vary the distance between the movable side wall and a fixed side wall in response to variations in the dimension of coin receiving chamber. CONSTITUTION:A chute 6 for guiding coins into an accumulating portion 7 is defined by one fixed side wall 51 located near and above main rollers 11 and 12 and the other movable side wall 52 located oppositely to the former. By the action of a driving mechanism taking place in response to coin type selection function performed prior to coin packing operation, the diameter of a coin receiving chamber 16 is reduced, in the case of a smaller diameter of a coin 100 to be packed, concurrently with a reduced distance between the lower part of the movable side wall 52 of the chute 6 and the fixed side wall 51 thereof and, in the case of a larger diameter, the coin receiving chamber 16 is enlarged, concurrently with the lower part of the movable side wall 52 of the chute 6 moving away from the fixed side wall 51 thereof, whereby the distance between the movable side wall 52 and the fixed side wall 51 is varied in response to variations in the diameter of the coin receiving chamber 16. Therefore, the structure of the coin guiding portion can be simplified substantially.

Title: Production of resin coated sand grain for shell mold
Inventor: TERAMOTO TSUTOMU
IPC: B22C1/22
Filed: 1984-10-31
Abstract: PURPOSE:To obtain titled sand grains which are low in odor and have excellent bending strength, etc. by adding urea to the heated sand grains and solid resol type phenolic resin during kneading in the stage of kneading said sand grains and resin and obtaining the titled sand grains. CONSTITUTION:The resin coated sand for a shell mold is produced by kneading the heated sand grains and the solid resol type phenolic resin. The urea is added at 0.5-5.0pts.wt. to 100pts.wt. the solid resol type phenolic resin during kneading in the above-mentioned method. The addition of the urea can be executed by an either method of mixing the urea into the solid resol type phenolic resin or dissolving the urea to cooling water and adding the cooling water to the resin. The latter method is more preferable as the addition is easy with said method. The resin coated sand for the shell mold having the excellent bending strength is thus produced even if the amount of the resin to be used is small.

IPC: A63F7/02
Filed: 1999-08-16
Abstract: PROBLEM TO BE SOLVED: To provide a game machine capable of delivering lent balls accurately and quickly. SOLUTION: When a lent ball request occurs, balls guided from above are delivered downward by a ball delivering screw provided in a case 198, and one ball is discharged each time the screw is half-rotated.

The screw is temporarily stopped when the counted result reaches the expected number. If the delivery number lacks after referring to the counted result by the detection of the switch 301B, the screw is again rotated to deliver the lacking number of balls.

Title: Semiconductor device
Inventor: MATSUMOTO KAZUYA
IPC: H01L21/8234
Filed: 1985-10-17
Abstract: PURPOSE:To enhance the static electricity of an input terminal and to make the terminal withstand a surge by composing at least part of an input protecting circuit of an electric resistor inserted in series with an input circuit and a MOS transistor inserted in parallel with the resistor. CONSTITUTION:An enhancement type MOS transistor 6 inserted in parallel with a polycrystalline silicon protecting resistor 5 is normally OFF, and a current flows through the resistor 5. When the voltage across the resistor 5 alters, the transistor 6 is connected in parallel with the resistor 5. Accordingly, when the voltage across the resistor 5 exceeds the punch-through voltage of the transistor 6, a current starts flowing between the drain and the source of the transistor 6, and a current flowing to the resistor 5 is limited. Consequently, it can prevent the internal circuit from damaging due to the static electricity or surge.

Title: Holographic exposure apparatus for reducing pseudo hologram noise
Inventor: GEIROODO II MOSU
IPC: G03H1/00
Filed: 1990-08-31
Abstract: PURPOSE: To reduce the production of noise inside a head-up display(HUD) hologram by moving a point light source toward a recording medium during the exposure of a holographic optical element. CONSTITUTION: This device is placed within a specified distance from the beam source of coherent energy for the exposure of a recording module 2. Since the moving amount of a point light source 28 is a little and a relative optical path length change is a little as well, a phase change between an incident beam and a reflected beam is reduced. In contrast, the noise to prepare a pseudo hologram shows an extremely remarkable distance change and a comparatively large shift is produced in the interference fringes of noise hologram. When these phase shifts reaches a half wavelength, the noise hologram is essentially erased. However, the quantity of shift of the hologram is originally just about 1/20 of a designed wavelength. Thus, the noise can be effectively removed.

CONSTITUTION:On the basis of information from potentiometers 9, 10, and 11, the attitudes of an arm 6 and a bucket 8 in relation to the vehicle are detected and the excavation depth (h) in relation to the ground is measured by a device 13 provided to a displayer 12. On the basis of the results of a device 19 to compare the measured value (h) and an excavation target value H in a setter 15, the first, second, and third buzzer operating devices 16, 17, and 18 are operated when the measured value (h) is in the first and second set ranges A and B and nearly equal to the target value H, and working signals 16a, 17a, and 18a are sent to an automatic alarm device 14 from which a different kind of warning sound is generated. The breakage of objects being buried can thus be prevented and the efficiency of working can be raised.
