Title: Method of operating passenger conveyor
Inventor: TSUCHIYAMA HARUCHIKA
IPC: B66B29/00
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To safety stop a passenger conveyor at the time of detecting abnormality of the speed of a moving handrail by quickly stopping a moving handrail once and while gradually reducing the speed of steps, and driving the moving handrail again so as to synchronize the speed thereof with the speed of the steps at the time of detecting abnormality of the speed of the moving handrail. SOLUTION: When abnormality of the speed of a moving handrail is detected, a moving handrail speed abnormality detecting device 16 energizes a moving handrail driving chain opening plunger 13 and a moving handrail driving roller opening plunger 15 so as to cut off the moving handrail driving force. Continuously, a speed reduction command is output to an inverter 20 so as to reduce the speed of the steps, and the moving handrail is started again. At the time of reducing the speed of the steps, speed is reduced to the preset speed for operation. When the moving handrail is accelerated and synchronized with the speed of the steps, the speed reduction command is output to the inverter 20 again so as to stop the escalator. After the escalator is stopped, an electromagnetic brake 9 is started.

Title: Projector-type headlamp
Inventor: FUTAMI TAKASHI
IPC: F21S8/12
Filed: 1998-10-27
Abstract: PROBLEM TO BE SOLVED: To freely set the distribution of quantity of light in a light distribution pattern and to ensure long-distance visibility. SOLUTION: This headlamp 1 is made up of a oval projection lens 2 with its center part being a cylindrical lens part 2a having a substantially horizontal linear focus fL and combined at both its horizontal ends with halved aspherical lens part 2b, and a reflector 3 with a vertical cross-section representing an ellipse having a first focal point in the proximity of an illuminant 4 and having a second focal point in the proximity of the linear focus and with a horizontal cross-section representing a free-form curve giving a desired horizontal radiation angle. Because the cylindrical lens part 2a of the oval projection lens 2 is prevented from producing any horizontal optical action and the reflector 3 provided behind it is enabled to contribute to the formation of a light distribution characteristic, the quantity of light is freely distributed.

Title: Display device
Inventor: MATSUMOTO TAKESHI
IPC: G02B5/32
Filed: 1989-11-24
Abstract: PURPOSE:To improve visibility and to prevent an image from being deteriorated by providing a light selection means for allowing only light which reaches an observer by 1st-order diffraction out of light made incident on a non-regular reflection type holographic optical element to selectively advance between a display medium and the non-regular reflection type holographic optical element. CONSTITUTION:A blind 13 is disposed between a reflection type holographic optical element(HOE) 11 and a display device 12, and has a function for selectively transmitting only the light which reaches the observer by the 1st-order diffraction out of the light emitted from the display device 12 to respective directions. Therefore, the light(an alternate long and short dash line) which reaches the observer by regular reflection and the light(a broken line) which reaches the observer by high-order diffraction when the blind 13 does not exist are shielded by the blind 13, so that the light does not reach HOE 11. Thus, only the light which reaches the observer by the 1st-order diffraction is selectively projected to the HOE 11, and the observer 14 views only one display of the display device 12 in the visual field, thereby improving the visibility.

Title: Keybutton
Inventor: INUBUSHI TOSHIYA
IPC: H01H13/02
Filed: 1988-12-02
Abstract: PURPOSE:To make a hard coat unnecessary and to permit making free developments in design, by mounting a colored key bottom on the lower part of a transparent key top and forming such structure as making a print on the joint surface of the lower part. CONSTITUTION:The transparent key top 14 of a keybutton 1 is first moulded of a resin, and then a letter 17 or the like is printed on the reverse of the key top. Subsequently, a colored key bottom 15 is mounted of a resin by utilizing the resin layer printed on the reverse as an insert. Mounting of the colored key bottom 15 on the lower part of the transparent key top 14 makes the projecting part 2 of the surface of the key bottom 15 entirely invisible from the surface of the key top 14 while making the bottom surface of the key top 14 visible as if it were the bottom surface of the key button 1. This makes a hard coat unnecessary while freely setting the color of the key bottom for permitting to select the color of the keybutton itself.

Filed: 1991-10-26
Abstract: PURPOSE:To enable continuous drawing without impairing the quality and characteristics of an optical fiber by heating and press-fitting the next preform while the front juncture of the optical fiber preform is drawn in a heater. CONSTITUTION:Burners 4 are moved to near the rear end face 6 of the optical fiber preform A and are lowered down to near the rear end face 6 of the optical fiber preform A held by a 2nd delivery device 3 when the front end molten part, i.e., front juncture 5, of the preform A is begun to be drawn. These two end faces 7, 6 are heated up to a prescribed temp. with the burner 4 and are then press-fitted. The preform A held in the 1st delivery device 1 is released to free the 1st delivery device 1 when the 1st delivery device arrives at the lower limit of its vertical moving range. The connection is thereby completed. The two optical fiber preforms in the connected state are eventually held by only the 2nd delivery device 3. On the other hand, the 1st delivery device 1 moves upward so as to be ready for holding the fresh optical fiber preform.

Title: Hydraulic pipe fixing guide of construction machine
Inventor: YOKOTA KENICHI
IPC: E02F3/36
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To efficiently release the movement while maintaining the fixing action of hydraulic pipe by arranging rollers so as to sandwich the hydraulic pipe. SOLUTION: Upper/lower frames of a fixing guide 1 are formed as rollers 10, 11. The rollers 10, 11 are fixed by allowing a hose to abut to the rollers from above and below. That is, in this fixing guide 1, there is no vertical directional play in a fixed state of the hose 2, so that the hose 2 is sandwiched/fixed by the upper/lower rollers 10, 11. Then, a longitudinal directional movement of the hose 2 is released by rolling of the rollers 10, 11 to thereby previously prevent hydraulic pipe from being abraded and damaged by contacting with the fixing guide 1 as well as to obviate winding of a guard member round the hydraulic pipe.

Title: Manufacture of semiconductor device
Inventor: OKADA KATSUYA
IPC: H01L21/76
Filed: 1991-11-22
Abstract: PURPOSE:To improve isolation breakdown strength between elements of a semiconductor integrated circuit wherein selective epitaxial growth technique is used. CONSTITUTION:After an oxide film 2 of an arbitrary thickness which is necessary for element isolation is deposited on a P-type silicon substrate 1, an active region is opened and a P-type silicon single crystalline layer is selectively formed by epitaxial growth thereon. Thereafter, impurities of enough concentration for strengthening isolation breakdown strength of an element are injected over the oxide film 2 and a P-type epitaxial growth layer 3 around an area near an interface between the oxide film 2 and the P-type silicon substrate 1, and an N-type impurity diffusion layer 7 which becomes a source/drain is formed and activated. Since an impurity diffusion layer of high concentration is thereby formed in an oxide film between elements and below an epitaxial growth layer, isolation breakdown strength between elements is improved.
