Title: Refuse sorter
Inventor: IMOTO SEITARO
IPC: B07B9/00
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To surely sort combustibles and aluminum cans by providing a sorter with a second sorter for injecting gas to the refuse discharged from a refuse discharge section and sorting light objects and heavy objects, then sorting the light objects to the aluminum cans and the combustibles. SOLUTION: The combustibles of the discharged refuse are flown upward by the air flow injected from an injection section 41a and the incombustible heavier than the combustibles are dropped onto an incombustible recovering hopper 35 just before the injection section. At that time, the lightweight aluminum cans among the incombustibles include in the combustibles flown upward in some cases, but the aluminum cans included therein are dropped onto a scooping body 5. The combustibles falling onto this scooping body 5 are transported to the front end side on a rod 52 by the vibration of the scooping body 5 and are dropped from the front end onto a combustible recovering hopper 47. The aluminum cans are introduced to the incombustible recovering hopper 46. As a result, the intrusion of the aluminum cans into the combustibles is prevented and the sorting accuracy is improved.

Title: Method of controlling ignition timing of engine
Inventor: SASAKI ATSUSHI
IPC: F02P5/152
Filed: 1990-02-17
Abstract: PURPOSE:To prevent overheat of a catalyst and an exhaust pipe or the like in an exhaust system so as to improve durability by gradually decreasing a maximum delay timing value of ignition timing corresponding to a rise of an engine speed in a high speed region exceeding the predetermined engine speed. CONSTITUTION:In the ignition timing control method of an engine 1 constituted so as to adjust the ignition timing being based on an output signal of a knocking sensor 2, a maximum delay timing value of the ignition timing is gradually decreased corresponding to a rise of an engine speed in a high speed region exceeding the predetermined engine speed. By this constitution, since the maximum delay timing value of the ignition timing is gradually changed to an advance timing side corresponding to the rise of the engine speed in the high speed region exceeding the predetermined engine speed, a delay timing over condition is prevented from being continued even when an operation condition of this maximum delay timing value or in the vicinity of this value is continued and even when the delay timing over condition is continued. Accordingly, an exhaust temperature can be decreased by avoiding an excessive increase of gas temperature in the latter period of an expansion stroke.

Inventor: ENAMI NORIYUKI
IPC: B60K20/02
Filed: 1995-02-02
Abstract: PURPOSE: To simplify a housing structure and an housing method for a select lever. CONSTITUTION: A tilting shaft 16 of a select lever 2 is arranged in a bracket 14 which is freely rotational to a housing 13. In the most forward tilting position (a) of the select lever 2 to the bracket 14, a rotational shaft 15 of the bracket 14 is matched with an arm 3 arranged in the select lever 2. In the matching part with the arm 3, an end part of a select cable 4 is pivoted. When the select lever 2 is positioned in the position (a), in other words, a P-range is selected, the select lever 2 is rotated integrally with the bracket 14 forward/backward to the housing 13 while setting the end part of the select cable 4 as the center of rotation. Therefore, the select lever 2 can be stored while a tensile condition of the select cable 4 is maintained.  As the housing operation of the select lever 2 can be carried out as a series of actions with P-range selecting operation, an operation method can be simplified.

Title: Image recorder
Inventor: SEGAWA HIDEO
IPC: B41J2/44
Filed: 1978-03-31
Abstract: PURPOSE: To enable image recording of superior reproducibility and high accuracy by condensing the divergent light from a semiconductor laser or light emitting diode by the use of a lens of large numerical aperture.  
     CONSTITUTION: A light source 1 is the semiconductor laser array configured with four semiconductor lasers a thru d in one array and its oscillation is controlled and is light-modulated as the image signal 2 is binary-coded and is applied by a signal processing unit 3. The exit light from each semiconductor laser 1 is condensed by a condensing lens 5 of large numerical aperture NA and is reflected in the specified direction by a rotary polyhedral mirror 6. The reflected light from the rotary polyhedral mirror 6 is imaged on the surface of a photoreceptor 9 by an fθ lens system 8  and is thereby imaged on the surface of the photoreceptor 9 having beforehand been  charged, thus subsequently forming the electrostatic latent images for four lines in  the width direction of the photoreceptor. Even if the semiconductor lasers emitting  divergent light are utilized as a light source, these are sufficiently condensed by the  lens of large numerical aperture, whereby the image recording of high speed is  accomplished.

Title: Electric window shutter device
Inventor: KITANAKA KOJI
IPC: E06B9/80
Filed: 1999-02-16
Abstract: PROBLEM TO BE SOLVED: To make an electromotor stop and turn in reverse automatically even in the case where a contact pressure sensor gets out of order and becomes unable to detect a catch of a foreign matter by a method wherein a reference time of decision for a closing motion is set in a controller of an electric shutter. SOLUTION: An electric shutter device 1 installaed at a window W of a dwelling house opens and shuts a window shutter 2 wound round a drum 6 by operation of an electromotor 7, and stops its operation when a full-opening or a full-shutting is detected by limit switches 81 and 82. When a contact pressure sensor 83 made of a pressure-sensitive conductive rubber provided at a bent part 21 at the lower end of the window shutter 2 detects a catch of a foreign matter during a shutting motion, the shutter device interrupts the shutting motion and moves to an opening motion. Furthermore, when the time of shutting motion exceeds a reference time Tc of decision set in a memory of a controller 8, the shutter device interrupts the shutting motion and moves to the opening motion.  Therefore, the electromotor 7 is stopped and turned in reverse automatically even though the contact pressure sensor 83 gets out of order and becomes unable to detect the catch of the foreign matter, and thereby the electromotor 7 can be prevented from being damaged.

IPC: G06F9/38
Filed: 1982-03-09
Abstract: PURPOSE:To shorten the executing time of an instruction sequence, by holding a data at a buffer register and then reading the contents of the data in case a writing instruction and a reading instruction are executed consecutively to the same arithmetic register. CONSTITUTION:A writing instruction and a reading instruction are supplied consecutively to the writing and reading registers 9 and 10 respectively. Then both instructions are fed to an arithmetic register 8 and at the same time compared with each other at a coincidence detecting circuit 14. When the coincidence is obtained from the comparison, those instructions are held at a buffer register 13. The data of the register 13 is selected 11 although the data of the register 8 is varied by the instruction 9. Thus it is possible to read out the first data, and no waiting is needed for the input of the next instruction. This can shorten the executing time of an instruction sequence.

Abstract: PURPOSE: To automatically find the position of a boundary between an unexposed area being a shadow projected by an X-ray opaque member in an X ray picture and the picture area of an object by including a specific process. CONSTITUTION: This method for judging the position of a signal/shielded shadow part boundary in an X-ray picture is constituted of the following processes. That is, low level primitives are extracted from the X-ray picture, the reduced number of intermediate level primitives are prepared from the low level primitives, assumed picture areas related with the position of the signal/shielded shadow part boundary are constructed from the plural combination of the intermediate level primitives, each combination is intermediate level-inspected, and the partial or whole assumed picture areas are rejected or accepted. Then, high level inspection is executed for each assumed picture area, the assumed picture areas are rejected or accepted with a little loss, and the assumed picture area at the minimum costs is selected.  That is, many assumptions are established for the position of the boundary, and it is finally decided that those assumptions are correct based on a result obtained by executing the plural high level tests for each.
