Patent number: 4586432Abstract: A printing mechanism is described which comprises a plurality of setting wheels (16) mounted coaxially on a sleeve (28). With the setting wheels type bands (20) carrying printing types (22) are in a drive connection. In the sleeve (28) a setting shaft (42) is arranged rototably and axially displaceably. In the sleeve a slot (30) extending in the axial direction is disposed through which a tooth (36) disposed on the setting shaft engages in radial recesses (46) in the hub region of the setting wheels. A detent means comprising detent recesses in the inner region of the sleeve, into which an axially immovable detent element (54) engages, defines axial detent positions of the setting shaft. In the sleeve at least one further slot extending in the axial direction is disposed. The detent recesses are disposed in the inner region of the sleeve in a plurality of axial rows and in each row they have a different detent spacing.Type: GrantFiled: February 21, 1985Date of Patent: May 6, 1986Assignee: Esselte Pendaflex CorporationInventor: Heinrich Volk

Patent number: 4583457Abstract: The invention relates to a printing mechanism comprising a plurality of setting wheels (16) which are mounted coaxially on a sleeve (28) and with which type carriers (20) carrying printing types (22) are in a drive connection. In the sleeve (20) a setting shaft (42) is disposed axially displaceably and rotatable therewith. Disposed on the setting shaft is at least one tooth (36, 38, 40) projecting through a slot (30, 32, 34) extending in the axial direction in the sleeve (42). This tooth (36, 38, 40) can be brought by axial displacement of the setting shaft (42) into engagement with radial recesses (46) in the setting wheels (16) disposed in the hub region of the setting shaft (42). The slot (30, 32, 34) formed in the sleeve (28) is open in the axial direction at one end of the sleeve (42) and closed at the other end and at the end of the sleeve (28) at which the slot (30, 32, 34 ) is open a spreading or expansion means (60) is disposed which keeps the sleeve internal diameter constant.Type: GrantFiled: February 21, 1985Date of Patent: April 22, 1986Assignee: Esselte Pendaflex CorporationInventor: Heinrich Volk

Patent number: 4583456Abstract: A printing mechanism is described comprising a housing (12, 14) in which a plurality of type carriers (20) are disposed which are in a drive connection with coaxially disposed setting wheels (16) each having a center bore. In a space formed by the center bores of the setting wheels a setting shaft (42) is axially displaceable and rotatable. By axial displacement the setting shaft can be brought into a drive connection with each of the setting wheels. On the setting shaft an actuating knob (48) is disposed with the aid of which said shaft can be displaced and turned. In the housing a display indicator means (26, 27, 29) is disposed displaceably parallel to the setting shaft; said means is connected to the setting shaft in such a manner that the latter turns relatively thereto but can be displaced axially only jointly therewith. The display indicator means makes it possible to recognize the type carrier which can be adjusted in the respective axial position of the setting shaft.Type: GrantFiled: February 20, 1985Date of Patent: April 22, 1986Assignee: Esselte Pendaflex CorporationInventor: Heinrich Volk

Patent number: 4582720Abstract: A substrate introducing chamber, a reaction chamber and a substrate removing chamber are sequentially arranged with a shutter between adjacent ones of them. One or more substrates are mounted on a holder with their surfaces lying in vertical planes and carried into the substrate introducing chamber, the reaction chamber and the substrate removing chamber one after another. In the reaction chamber, a material gas is guided by gas guides to flow along the substrate surfaces in a limited space in which the substrates are disposed. The material gas is ionized into a plasma through the use of high-frequency energy obtained across a pair electrodes. The line of electric force of the high-frequency energy is directed along the substrate surfaces. By ionization of the material gas into the plasma, a non-single-crystal layer is formed, by deposition, on each substrate. At this time, the substrates are floating off the high-frequency energy source.Type: GrantFiled: September 20, 1983Date of Patent: April 15, 1986Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventor: Shunpei Yamazaki

Patent number: 4581535Abstract: A stack of many stimulable phosphor sheets and an X-ray tube are positioned with an object intervening therebetween, and moved with respect to each other around a tomographic plane in the object so as to satisfy the linear rule and the geometric rule in the course of exposure of the object to X-rays, thereby storing images of many tomographic planes in the stimulable phosphor sheets in a single recording step. The respective stimulable phosphor sheets are then exposed to a stimulating ray to cause them to emit light, the emitted light is photoelectrically read out, and the obtained electric signals are reproduced as visible tomographic images usable in diagnosis with high efficiency and accuracy. The electric signals may be superposed one upon another and reproduced as an X-ray image of any slice thickness, particularly a slice thickness of 5 mm or more, which is free from interfering shadows.Type: GrantFiled: October 12, 1982Date of Patent: April 8, 1986Assignee: Fuji Photo Film Co., Ltd.Inventors: Takao Komaki, Hirosi Tanaka, Nobuyoshi Nakajima

Patent number: 4449405Abstract: Disclosed is a capacitance level measuring device comprised of a container whose level is to be measured and a probe inserted into and spaced from the container. The capacitance between the probe and container varies in relation to the level in the container. A capacitance measuring circuit determines the capacitance between the probe and container and thus indicates the level in the container. The integrity of the probe is verified by constructing the probe so as to include it in a series circuit, as well as the capacitance measuring circuit, and a lack of continuity in the probe is indicative of questionable probe integrity. The question as to the probe's integrity would indicate a questionable level indication from the capacitance measuring circuit. Various probe constructions are also disclosed.Type: GrantFiled: July 14, 1981Date of Patent: May 22, 1984Assignee: Endress u. Hauser GmbH u. Co.Inventors: Han-Jurgen Franz, Volker Dreyer
