Patent EP-0278429-A2 (EP)
Inventor: OBELODE JURGEN
IPC: H04M1/08
Filed: 1988-02-05
Abstract: The functions of the hook switch and a manually operable switch device which simulates the hook switch are combined by means of a bistable relay (23) which actuates the hook switch contacts (12, 13). The bistable relay (23) is set by the actuation of two make contacts (30, 31) when the handset is lifted or replaced or an additional key is pressed. It is reset by means of a control device (34), which continuously evaluates the switching state of the two make contacts (30, 31). The setting circuit of the bistable relay (23) contains a switching transistor (24), the control circuit of which is actuated by means of the make contacts (30, 31). The control circuit or the operating circuit of the switching transistor (24) may contain a switching threshold (27, 27'). <IMAGE>

Inventor: FUKUDA TSUGUHIRO
IPC: B41J31/09
Filed: 1988-03-02
Abstract: An erroneously recorded image among recorded images on a recording medium is corrected by a correction sheet (5) comprising an adhesive layer (2, 3) on a support (1). The adhesive layer (2, 3) is heated to develop an adhesive force and caused to adhere to the error image and peel the error image when the correction sheet is separated from the recording medium. The adhesive layer (2, 3) comprises a laminate structure including a separation prevention layer (2) and an upper layer (3), and the separation prevention layer (2) is in charge of cohesion strength, intimate adhesion to support and flexibility under heating of the adhesive layer (2, 3). Because of the laminate adhesive layer structure, the correction sheet (5) allows for adequate correction of an error image even on a recording medium (6) with poor surface smoothness without causing correction failure, such as reverse transfer.

Abstract: Abstract Technical object Provision of a height adjustment device with a reliable and at the same time easy-to-handle adjustment locking mechanism.  Solution of the technical object The two tube profiles (1 and 2) of the height adjustment device which can be adjusted with respect to one another are constantly penetrated by a locking unit (3) both in the lokced and in the non- locked state, that is even during the adjustment process. The lever (9) can be latched and unlatched via longitudinal displacement at the level (14) of the connecting element (8) at the securing pin (5) and by rotating the lever (9) the connecting element is entrained in such a way that in the case of a 90 DEG  rotation it releases the profile tubes 1 and 2 which are locked to one another, for the purpose of changing their positions with respect to one another.  Area of application Tarpaulin cover frame for loading ramps on lorries as well as all other devices which contain a height adjustment device. <IMAGE>

Abstract: This invention concerns a humidity sensor wherein a chemical conversion coating, giving attention to the property that it undergoes an impedance decrease with adsorption of moisture, is used as humidity sensing element which is characterized by an extremely short electrode distance, greatly improved sensitivity, high speed response, stable performance over a long period of time, high reliability and cheaper production cost. 
     The principal point that characterizes the humidity sensor in this invention is that the chemical conversion coating deposited on the metal surface with or without en electrolysis application, is made usable as a humidity sensing element. For the chemical conversion coating, such coatings as phosphate, oxalate, titanium fluoro-complex, chromium phosphate and non-chromium types are used. 
     On top of this chemical conversion coating, application of a humidity sensing film is effected to further improve humidity sensing performance.

Abstract: The disclosure concerns the control of fuel injection for automatic engines. It is an object of the invention to simulate the accuracy of fuel injection control that would be obtained with flow sensors and pressure sensors, without actually employing such sensors. This is true because the theoretical model used for estimating the flow is not matched with actual system performance. In such a case, matching is an object of the invention. These objects are obtained by estimating a level of the atmospheric pressure, a flow of air passing through a throttle valve and a flow of air flowing into the cylinder, and controlling the fuel injection based upon the flow of air flowing into the cylinder. The result is a highly accurate estimation of the valves.

Abstract: So that a furniture, by means of which a wing (2) can be transferred from a locking position into an unlocking position and tilting position, is prevented from changing over undesirably from the tilting position to a parallel parking position, a releasable blocking device (10) is located on the lower horizontal spars of the frame (1) and of the wing (2). The release is obtained by means of the rotary handle (8) which also causes the unlocking. The blocking device (10) can be retained, by means of a blocking apparatus (15) installed according to the invention, in an inoperative position which makes it possible for the wing, without being impeded by the blocking device (10), to be moved as often as desired from the parallel parking position into the tilting position and vice versa. <IMAGE>

Abstract: The composition of an inorganic powder proposed by the in­vention is an extrusion-molding composition for shaping a green body for sintering. The composition is prepared by using an orga­nic polymer as a binder and an organic solvent. Characteristically, the composition contains a limited amount of a sorbitan fatty acid ester or polyoxyethylene sorbitan fatty acid ester ether. By virtue of this unique ingredient, the composition is freed from the prob­lems due to evaporation of the solvent to cause a change in the moldability and stagnant staying of the composition in the extrud­er machine by sticking to the walls. Also, the composition solves the problem due to oxidation of a non-oxide inorganic powder when the powder is compounded with water and a water-soluble polymer as the binder followed by drying.
