Title: Ball charging apparatus for game machine using pinballs
Inventor: NIIYAMA KICHIHEI
IPC: A63F7/02
Filed: 1987-10-09
Abstract: PURPOSE: To judge the fault of an abnormal situation or the like and to prevent unreasonable profits from being given by starting a game when the detection values of both detection means respectively disposed on the upstream side and downstream side of a fetching flow passage for fetching Pachinko balls (used in Japanese pinball game) into a game machine by each unit match. CONSTITUTION: Only a first standby sensor S5 is provided on a position for detecting not a fifth one from a head but a sixth one on the upstream side for one ball from it. The number of balls passing through the standby sensor S5 is counted and a passing ball sensor 65 is constituted of a reflection type photosensor composed of a light emitting/receiving element pair and counts the number of the balls passing through the flow-out port of a fetching gutter 34 as well. In the case that the prescribed unit ball number of the Pachinko balls are fetched from a ball sheath 33, when the number of the balls passing through the flow-out port of the fetching gutter 34 is less than the unit ball number whose presence is confirmed in the standby sensor S5, it is judged that some accidents, a flow-down defect by dust on a flow-in gutter 32 and a dishonest act by a piano wire, etc., for instance, are present in the presence section of the ball sheath 33, and the start of the game is stopped.

Title: Digital-analog converter
Inventor: YANASE TAKAO
IPC: H03M1/66
Filed: 1984-12-04
Abstract: PURPOSE:To attain a simple converter at a low cost by constituting the digital- analog converter having a multiplication function of four quadrants type that a digital input signal is inputted non-invertedly or invertedly corresponding to the polarity of an analog input signal. CONSTITUTION:When the polarity of an analog input signal Vi is positive, the analog input signal Vi is inputted to a D/A converter 10 via a full wave rectifier 16b while keeping the amplitude and polarity as they are. In this case, the output of a polarity discriminator 12 is a low level L. When the polarity of the analog input signal Vi is negative, the analog input signal Vi is rectified by the full wave rectifier 16, the polarity is positive while the amplitude is kept the same and the result is inputted to the D/A converter 10. Since the output of the polarity discriminator 12 is a high level H in this case, the polarity of logic is inverted for the digital input signal by an exclusive OR circuit 14 and the result is inputted to the D/A converter 10 Thus, the polarity of the digital input data is inverted. Then a unipolar D/A converter with comparatively low cost is used.

Abstract: PURPOSE:To prevent the damage in outside boards and, at the same time, to promote durability by coating the outside of a main body with a buffer reinforced material 10 of a friction resin having friction factor smaller than that of the main body, and reducing frictional resistance of the outside of the main body. CONSTITUTION:For example, urethane rubber is used to form a main body 6 of a projected or a semi-cylindrical fender 5. The outside of the main body or at least of the front end of the projection is coated with a buffer reinforced material 10 of low friction resin. For example, the top 6a of the main body 6 is coated by baking teflon resin having friction factor smaller than that of the urethane rubber of the main body 6. Instead of baking, a recessed gutter is provided to the top 6a, the buffer reinforced material 10 is buried in the recessed gutter, and bolts can be used for fastening them. For example, the fender 5 is fixed to a quaywall face. Impact force caused by a collision between outside boards is absorbed by elastic deformation of the outside of the main body.

Title: Growth of semiconductor layer and manufacture of compound semiconductor device
Inventor: YOKOYAMA MITSUNORI
IPC: C30B29/40
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To obtain satisfactory deposition speed even in a large deposition device such as a batch type one, by forming a selective growth layer by using dimethyl gallium chloride as a raw material of Ga. SOLUTION: Dimethyl gallium chloride(DMGaCl) is held in a bubbler 15A as Ga source. Since vapor pressure of DMGaCl is 0.5 Torr or more at a room temperature, satisfactory deposition speed can be obtained in a reaction chamber 11 even in bubbling at a room temperature. Therefore, even if a raw material of another group III element is held in an adjacent bubbler and III-V mixed crystal containing Ga and another group III element is formed on a substrate 11D in the reaction chamber 11, bubblers do not thermally interfere each other. Therefore, a selective growth layer can be formed without producing precipitate on a semiconductor layer, and satisfactory deposition speed can be obtained even in a large deposition device such as a batch type one.

Abstract: PURPOSE:To prevent a photometry condition from being changed from that at an ordinary photographing time and to realize photographing by precise exposure even when a panoramic adaptor is used for a camera provided with a TTL function by making the reflectivity of the lens facing surface of the panoramic adaptor provided with an aperture for panoramic photographing and the reflectivity of a film almost identical. CONSTITUTION:The panoramic adaptor 2 is provided with the aperture part for panoramic photographing 3 and the size of the film is changed to 36mmX13mm from 36mmX24mm by the aperture part 3. Then, when the adaptor 2 is assembled to a camera main body 1 so as to be positioned at the front surface of the film, the panoramic-size photographing of the aperture part 3 is executed. In such a case, since the reflectivity of the lens facing surface of the adaptor 2 is almost identical to the reflectivity of the film, photometry is executed by the identical condition to the condition when the adaptor 2 is not assembled and the photographing by the precise exposure is executed. Besides, when the adaptor 2 is removed from the camera main body 1, the ordinary photographing of 36mmX24mm is executed.

Filed: 1992-08-31
Abstract: PURPOSE:To drive a rod into a material in a proper attitude by contacting an inward protruding part with the peripheral surface of a major dia. part of a tool to hold a chuck in a closed condition when the tool major dia. part passes the inward protruding part. CONSTITUTION:A nose top 17 contacts the oversurface 35 of a material and stops, and an actuator is operated to contact the tip of a blade 11 with the head of a nail 15. In this condition, the foremost part of a major dia. part 24 is positioned just in front of the tip of a bolt. When the blade 11 is further sunk, the nail 15 is pressed by the blade 11 and fitted by pressure into the material. While the major dia. part 24 is passing the bolt, its tip contacts the peripheral surface of the major dia. part 24, so that a chuck 12 is not able to open the tip, and the closed condition is held surely. Accordingly the nail 15 is driven vertically into the oversurface 35 of the material.
