Title: Optical fiber connecting mechanism and optical connector using the same
Inventor: TAKIZAWA KAZUHIRO
IPC: G02B6/36
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To stably and surely maintain the connecting state of an optical fiber by applying pull-out resistance to the optical fiber by engaging pawls projected on both clamp members into the cover of the optical fiber. SOLUTION: The optical fiber inserted from the back of a clamp member 29 into an optical fiber guide groove 36 is abutted with an optical fiber 26 on the side of a ferrule 24 in the state of inserting an opening member 42 into an inserting port 34 and opening an optical fiber connecting mechanism 25 (in the state of opening the clamp member 29 and clamp members 30 and 31) and afterwards, the opening member 42 is pulled out so that the optical fiber 26 or the like can be fixedly clamped and its connecting state can be maintained. At such a time, pawls 39 are engaged into both the sides of cover of the optical fiber, and sufficient pull-out resistance is applied to the optical fiber. Thus, the optical connector can omit or simplify parts for supporting pullout force to be exerted upon the optical fiber and miniaturization and cost down can be facilitated.

Title: Electric fan
Inventor: KOKETSU TADAAKI
IPC: F04D25/10
Filed: 1987-10-30
Abstract: PURPOSE:To improve a blowing effect as a result of automatic facing of the head part of an electric fan to a person by switching the present condition to the condition with a narrowed field of view of the sensor, when the existence of a person is sensed under the condition with the widened field of view of a sensor provided on the head part of an swingable electric fan. CONSTITUTION:In an electric fan, its head part having blowing impeller or the like is swingably supported by the main body thereof. Then, a case 20 is provided on the head part of the electric fan, and in this case 20 are provided a sensor 21 which senses the existance of a person in front thereof, and a means 23 which switches the field of view of the sensor 21 from wide to narrow angles and vice versa. When the existence of a person is sensed under the condition that the field of the view of the sensor 21 is widened, the field of the view is changed over to a narrow angle by the means 23, the head part of the electric fan is oscillated across the center line toward the person. Thus, the head part of the electric fan automatically faces to a person, thereby the blowing effect is improved.

Title: Roaster
Inventor: UEDA YASUKIYO
IPC: F24C3/12
Filed: 1988-11-01
Abstract: PURPOSE:To prevent the occurrence of a fire in a chamber and formation of a rise flame extended from a discharge port and to enable holding of safety by a method wherein a temperature sensor on the surface of which a catalyst is attached is provided in a chamber body, and by means of a signal from the temperature sensor, a heat source is controlled. CONSTITUTION:When, after a substance 8 to be heated is roasted, roasting is continued for a long time in a state that a substance 8 to be heated is erroneously left in a chamber body 1 by a user, temperature in the chamber body 1 is gradually increased. The temperature of oil steal from the substance 8 to be heated and combustible gas is also increased to a value being near an ignition point. In which case, even if the temperature is lower than the ignition point, oil steam and combustible gas making contact with a catalyst 10 attached on the surface of a temperature sensor 9 is started to burn only on the surface, and the temperature of the temperature sensor 9 is rapidly increased. In which case, since an electromotive force is also rapidly increased and the electromotive force of a thermocouple 6 for detecting flame is decreased, an electromagnet 11 is separated, a valve 14 and a valve seat 15 are closed to disconnect the feed of gas, and combustion of a burner 2 is stopped. Thus, combustion is stopped before the temperature of the substance to be heated and oil steam is increased to an ignition point, and a fire in a chamber can be prevented from occurring.

Title: Data compression method
Inventor: AJIRO ATSUSHI
IPC: H04N19/00
Filed: 1995-09-30
Abstract: PROBLEM TO BE SOLVED: To effectively compress desired data by including a discrimination code, which discriminates desired data to be displayed on a display picture, together with compressed data to easily discriminate the display data. SOLUTION: For the purpose of reducing the number of picture elements of display data in the picture, preceding display data is subjected to exclusive OR. However, display data in the head is preserved as is. Thereafter, the data string is compressed by a data compression method. In this case, the data string is divided by 8 bits. Since the longitudinal size of the display picture on an LCD is 32 bits, the data string is divided by 8 bits, and data is compressed. At this time, data indicating the display data is included in upper two bits of the compression code at this time to compress data more effectively at need.

IPC: H01L29/78
Filed: 1987-11-04
Abstract: PURPOSE:To remove a problem of an increase in a contact diameter L due to alignment margins and to reduce the area of a chip by forming a well contact region and a source region in a self-alignment manner with a polysilicon gate electrode. CONSTITUTION:A well contact region is formed by diffusing an impurity from the polysilicon film 25 of a second pattern 29 formed simultaneously upon formation of a first pattern 28 of a polysilicon gate electrode. A source region is formed by an ion implanting method with the mask layers of the first and second patterns as masks. Thus, the well contact region and the source region are formed in a self-alignment manner with the polysilicon gate electrode, thereby eliminating the necessity of alignment margins to the gate electrode, the well contact region and the source region. The contact diameter L can be reduced the size of aligning margin of two times of photolithographies. Then, the area of a chip of a power transistor can be largely reduced.

Abstract: PURPOSE:To eliminate the need for skill in mounting operation with soldering and enable automation to be made by providing an opening at a central part of an needle support and then holding an inner edge of a hair spring into this opening and then half-fixing it. CONSTITUTION:An opening 6 with a zig-zag shaped guide part near a pivot 37 is provided at a boss 36 which is provided at a central part of a needle support 34. A size of this opening 6 is slightly larger than a line diameter of a hair spring 4 and an inner edge 41 of the spring 4 is inserted into this opening 6 for performing gear-locking for semi-fixing, namely tentative locking. Therefore, since the inner edge 41 of the spring 4 is tentatively locked to a guide part within the opening when mounting the inner edge 41 of the spring 4 to a support 34, pressing with forceps is not needed and soldering becomes extremely easy, thus eliminating the need for skill in operation and enabling automation to be made.
