Title: Method for measuring distance or angle by optical shadow read-out
Inventor: NAKAJIMA YOSHINORI
IPC: G01D5/347
Filed: 1994-04-25
Abstract: PURPOSE:To provide a measuring method to ease compact and highly accurate incorporation without malfunctions pulse-like motions, improve the reliability thanks to small number of constituting parts and improve the producibility when a position is to be recognized by adding/subtracting a pulse train for the optical measurement of distance or angle. CONSTITUTION:After a pattern corresponding to distance or angle is recorded on a glass plate or metallic plate in advance to form a master pattern 1, which is irradiated with the light emitted from a light source 2 and a photosensor 3 is placed in a shadow part of the light passing through the master pattern 1. Thus, a relative shift quantity parallel to the master pattern between the sensor 3 and master pattern 1 is read out to obtain the distance or angle.

Title: Fuel injection device
Inventor: ITO MASAYOSHI
IPC: F02M51/06
Filed: 1995-05-01
Abstract: PURPOSE: To guarantee stable fuel injection by reducing an amplitude of puressure pulsation, communicating an armature chamber in which an armature which can control a valve means is stored with a low pressure side communicating with a control pressure chamber by a plurality of passages so that pressure pulsation generated due to the discharge of high pressure fuel in the control pressure chamber into the low pressure side can be transmitted into the armature chamber through the plurality of passages. CONSTITUTION: In a fuel injection device, a three-way solenoid valve 20 is formed in its upper section and a fuel injection valve consisting of a body lower 11, a piston 12, etc., is provided in its lower section. A valve means of the three-way solenoid valve 20 consists of an outer valve 31, an inner valve 41, and a valve body 51. In this case, an armature chamber 30 at an upper end of the outer valve 31 is communicated with a recess 55 at a lower end of the outer valve 31 through two passages, namely a passage through a passage 58 and an annular groove 54 and a passage through a passage 59, a space section 61, a passage 56, and the annular groove 54. Consequently, pressure pulsation generated due to the opening of the outer valve 31 is divided into two passages, and fuel discharged from the armature chamber 30 suppresses the prevention of the transmission of pressure pulsation.

Title: Tape printer
Inventor: MORI SEIJI
IPC: B41J2/325
Filed: 1993-04-09
Abstract: PURPOSE:To selectively use a printing medium by a method wherein information of every kind is applied to two types of printing mediums, and the type of the printing medium is detected by a printing medium detection means. CONSTITUTION:A tape sprue 6 in use can commonly supply two types of tapes, i.e., a seal tape T1 and a film tape. Information of every kind applied to the seal tape T1 and the film tape is read through an analog sensor 20. In the discrimination between the seal tape T1 and the film tape, a first groove 23 is formed on an upper edge of release paper 21 of the seal tape T1, and the analog sensor 20 is so provided as to vertically move in contact with the upper edge of the seal tape T1. As a result, a first printing medium and a second printing medium of different types can be selectively used. The type of a printing medium can be easily specified without conducting any troublesome operation, and a printing control corresponding to the type of the printing medium can be conducted.

Title: Automatic detection of focusing
Inventor: HORIKAWA YOSHIAKI
IPC: G03B13/36
Filed: 1982-06-22
Abstract: PURPOSE:To improve considerably the sensitivity and accuracy of focusing, by noticing only the parts before and after the focusing where an abrupt change arises, using plural sets of sampling points and constituting an evaluation function. CONSTITUTION:An input image (g) is in the state of (c) in the stage of focusing. It is evident from the figures that the changes in the output difference between the positions A and B and the output difference between C and D are most significant in the change in sensor output with changes in a-f. Therefore, if an evaluation function f(X) is constituted as f(X)=(XA-XB)+(XC-XD), the output change can be detected with the highest sensitivity. The sampling points to be utilized are plural and the resistance to noise is improved. In actuality, the output from an image sensor is processed; therefore, if the value obtd. by subtracting the min. value from the max. value of the adjacent output differences is determined as the evaluation function, the conditions of the following equations hold.

Abstract: PURPOSE:To manufacture a fender in bilateral symmetric form by composing a duck for forming an inner bag of threads having different angles against the axis in a large diameter part and a small diameter part, and making the diameters equal in right and left when the internal pressure is applied into the inner bag. CONSTITUTION:A duck 14 to be the inner bag 1 is folded and fitted to the outer surface 3 of a mold 2 formed in semi-form of an inner bag 1, and the duck 14 is removed from the mold 2 after molding and volcanization to form the inner bag 1 having different diameters in right and left bordered in the central part. In this manufacture process, the duck 14 is made of multiple threads having different rigidity, and the angle of threads having the high rigidity of a large diameter part 6 side against the axial direction is made larger by the predetermined angle than the angle of threads having the high rigidity of a small diameter part 5 side against the axial direction. With this difference of the angles, the diameters of the right and left parts are expanded to the equal diameter in outline so as to be bilateral symmetric form when the internal pressure is applied into the inner bag 1. Next, an outer bag is covered for formation on the outer surface of the inner bag 1 under the condition that the air is pressed in the inner bag 1.

Consequently, changes such as the temperature, humidity, heat flow rate, etc. due to the influences exerted from both rooms 1, 2 are generated, detected by the sensor 15 and recorded by an automatic recorder which is not shown. Thus, the influences of the cloths exerted upon the human body can be simulated and measured under various atmospheric conditions and the measuring device can contribute the development of ideal cloths.

IPC: E04H6/42
Filed: 1992-03-31
Abstract: PURPOSE:To provide a stopper device for car delivery dolly, whose structure is sturdy and comparatively simple, which has a sufficient strength for bearing the load of a car, and which ensures that the maintenance and inspection works are performed easily. CONSTITUTION:A rotary shaft 64 is borne by a frame vertically, and the base end of an arm 62 is pivoted on this rotary shaft 64 with possibility of swinging up and down. A stopper roller 61 is extended at a right angle from the tip of the arm 62. The tip of arm 62 is lifted by a spring 68, and at normal times, the stopper roller 61 is positioned over a conveyor belt 2 so as to allow free revolution. When a wheel W of a car has pushed the stopper roller 61 down, the spring 68 elongates, and the arm 62 contacts a supporting bolt 69 on the frame 1, which thus bears the load. The rotary shaft 64 is rotated approx. 90 deg. in the regular and reverse directions by hydraulic mechanisms 66, 67, and the stopper roller 61 is revolved in reversals between the operating position and retracted position.
