Title: Throttle controller for engine
Inventor: ITOYAMA HIROYUKI
IPC: F01L1/26
Filed: 1990-11-29
Abstract: PURPOSE:To maintain torque prior to the change-over of a cam as it is for preventing operability from being degraded by controlling if necessary a throttle valve and ignition timing when the cam in a variable valve system is changed over. CONSTITUTION:There are provided a means 70 which calculates the reduction of throttle opening enlarged as an engine load is increased so as to provide identical torque in the stationary time on the basis of a detecting value sensed by an engine load sensor 69, and a means 71 which calculates an ignition timing delaying amount enlarged as the engine load is increased so as to absorb torque difference overshooting immediately after the change over of cam similarly on the basis of the sensor detected value. Also, a means 72 is provided which upon receiving the output of a cam changing over signal sets timing for closing a throttle valve prior to actual cam changing-over timing so as to absorb the torque increment remaining even after ignition timing delaying control. Thus, torque before and after the change-over of the cam can be maintained constant to maintain satisfactory operability.

Title: Reinforcing structure of optical fiber coupler
Inventor: KURAMOTO KIYOHIKO
IPC: G02B6/287
Filed: 1993-12-27
Abstract: PURPOSE:To make residual stress after curing of an adhesive small and to prevent degradation of a coupler assembly with lapse of time so as to improve its reliability by incorporating a stress buffer material into the adhesive for fixing the optical fiber coupler. CONSTITUTION:An SiO2-based filler or elastic spherical resin is incorporated as the stress buffer material into the adhesive at the time of fixing the optical fiber coupler 4 formed by heating, fusing and stretching plural pieces of optical fibers 10, 20 to a substrate 5 consisting of quartz glass, etc., by the adhesive 6. The SiO2-based filler is micropowder consisting essentially of silicon oxide and consists of components which are the same as or similar to the components of the quartz glass constituting clad parts 1, 2 of the optical fibers 10, 20 and, therefore, the powder does not apply a stress to a coupler body 4 at the time of curing of the adhesive 6. The shrinkage rate of the adhesive 6 is lowered by adding the SiO2-based filler thereto. On the other hand, the elastic spherical resin is spherical micropowder consisting of an acrylic resin, etc., and is capable of absorbing the residual stress at the time of shrinkage of the adhesive 6 on curing.

Title: Ladder exclusively designed for car roof
Inventor: SAKAMOTO KAZUCHIKA
IPC: E06C1/12
Filed: 1994-12-01
Abstract: PURPOSE: To enhance operability and functionability in a wide range and improve an outside appearance by enabling a ladder to move sliding along a support bar which is slidable in the crosswise direction and used as a supporter in structure. CONSTITUTION: A pair of support bars 2'a and 2'b installed inside a pair of base bars 2a and 2b supported on stays 1a and 1d mounted on a car loop are adapted to be slidable along two joint bars constructed on the base bars and arranged to support in a state which allows the joint bars to be penetrated into the lower part of the support bar 15a or the like, thereby fixing their spacing with two inside bars 16 or the like. A double-leg ladder is formed in such a fashion that a projection 4a or the like outside posts 5a and 5b may be fitted in a groove 36 or the like installed inside the support bars. A handle 7a or the like mounted on steps 8a or 8d are turned upward in the outside direction when using this ladder.  Since two projections on one side of the ladder are designed to be pulled into a post being interlocked with the turning of the handle, they are released from the grooves, it is possible to move the ladder slidingly by two projections installed on the opposite side to the released side.

Title: Ventilation device
Inventor: OCHI KAZUNORI
IPC: F24F7/007
Filed: 1988-12-27
Abstract: PURPOSE:To comfortably perform the air supply with a simple constitution regardless of seasons by respectively connecting the preheating operation switch and an auxiliary relay in parallel with a feed air damper, a feed air fan to the power source through the normally closed contact point of the auxiliary relay, a thermostat for water boiler in parallel with the normally closed contact point, and an ignition device to the normally opened contact point of the auxiliary relay. CONSTITUTION:When the ventilation switch 2 of a ventilating fan 1 is turned on, a feed air damper 3 is opened at the same time and a feed air fan 6 starts its operation to perform the normal ventilation as the pressure differential across the indoor side and outdoor side due to the ventilation is compensated. By turning on the preheating operation switch 4 in advance during the winter season, the normally opened contact point 9 of an auxiliary relay 5 is closed, and the boiler is ignited. As the temperature of hot water reaches a predetermined level, a thermostat 10 causes the feed air fan 6 to start as the outside air is preheated. On the other hand, the preheating operation switch 4 is turned off during the summer season. Because the normally closed contact point 8 of the auxiliary relay 5 then stays closed, the feed air fan 6 starts at the same time as the ventilation fan 1 with the boiler left stopped.

Abstract: PROBLEM TO BE SOLVED: To perform the remarkably precision work in addition to a high surface characteristic by intermittently performing the working, determining the contact of an electrode with a work during the interruption time by the electrical measurement to obtain the pulse impact coefficient, and determining the frequency of the contact. SOLUTION: The surface machining of a work is intermittently performed with the precision pulses to finish the precut work 6 with the desired surface characteristic of 0.1 μ. The percentage of the average contact of an electrode 5 with the work 6 to the measuring time is determined on the basis of the pulse impact coefficient in the measuring module 4, and the moving speed of the electrode is lowered and the machining time is increased when the pulse impact coefficient is over a reference value. Particularly the oscillation state of the electrode is recorded and stabilized through the pulse impact coefficient, and the interference self control effect of the electrode is solved with the pulse frequency of about more than 100 kHz, whereby the error in the precut can be prevented, and about 1 μm or less of the angle part error can be achieved.
