Title: Semiconductor ic device
Inventor: MORI TOSHIKI
IPC: H01L27/08
Filed: 1981-04-06
Abstract: PURPOSE:To prevent latch up by reducing parasitic transistor current amplification by a method wherein an inverse conductivity type region of high impurity concentration is provided reaching a buried region in a semiconductor layer near a resistor region high potential terminal in a bipolar IC. CONSTITUTION:In a bipolar IC with a plurality of P type diffused resistor regions 30 are formed in an N type epitaxial layer 20 that is an insular resistor surrounded with a P type insulating region 26, an N<+> diffused region 21 is formed around the layer 20 deep enough to reach an N<+> buried layer 22 encircling all the regions 30. An N P N transistor emitter diffused region 23 is provided partially overlapping the region 21, and a contact window 24 is bored wherein a metal wiring 25 is installed. The wiring 25 is connected to a power source and the layer 20 potential is kept at the maximum. Current amplification by a parasitic P N P transistor for which the region 30 acts as an emitter, the layer 20 as a base, and the substrate 1 as a collector, is reduced and the current into the substrate 1 via this parasitic transistor is in turn reduced and, consequentially, the false rise of the substrate potential is rendered smaller.

Abstract: PURPOSE:To prevent the damage of a photosensitive drum and to simplify a unit replacement action by releasing the fixing of a drum unit and other process units on a device main body and automatically separating the photosensitive drum from a developing unit. CONSTITUTION:When the drum unit 1 or a developing unit 2 is removed, an operator opens a front door 11, then turns a lever member 5 clockwise up to a position shown by an ideal line, holding a grip part 48. Then the engage ment of the drum unit 1 with the lever member 5 is released, and a link member 42 follows the release, turns by the prescribed angle and transmits its turn to a supporting spindle 36. A rocking member 6 turns, the developing unit 2 is pushed obliquely upward along a guide groove 35, and a developing roller 30 separates from the photosensitive drum 14. When the developing unit 2 is further pushed obliquely upward along the guide groove 35 due to the pressure of the rocking member 6, a click clack spring 45 is bent to the prescribed angle, and its direction where elasticity is energized is switched. Then a pressure lever 40 is away from a guide pin 32 and turnably rocked right above.

Title: Method for working stainless steel material
Inventor: KOUMITSU ARATA
IPC: B23K9/23
Filed: 1982-03-30
Abstract: PURPOSE:To transform the surface layer of an austenitic stainless steel material into the structure of austenite-ferrite dual phase stainless steel improved in stress corrosion cracking resistance, etc., by melting and then rapidly cooling said surface layer. CONSTITUTION:The surface layer, especially a part to depth below 1mm., of an austenitic stainless steel piece having the metallurgical structure composed of an austenitic single phase or an austenitic phase contg. a ferritic phase below a few % is melted. The melting is performed by an unconsumable elecrode-type arc welding method such as TIG. Since the melting is the purpose, the surface layer is melted by arc heat formed between an unconsumable electrode and the steel material without using a welding rod. Thereafter, the surface layer is rapidly cooled. Consequently, austenite-ferrite dual phase structure is formed in the surface layer.

Abstract: PURPOSE:To easily cut a bump, which has been pressure-bonded onto a semiconductor element, and a metal thin wire and to eliminate a cutting residue of the metal thin wire, on the bump, which can be cut at a part coming into contact with the bump by using the metal thin wire where constricted parts have formed in advance at equal intervals. CONSTITUTION:Constricted parts 7 are formed on a metal thin wire 2 immediately before a bonding operation. Wedges 9 are formed at a clamp 4; the constricted parts 7 are formed in such a way that they have a length, of the metal thin wire, which can form a metal ball at the metal thin wire 2, e.g., every 100-120mum, when the clamp is opened or shut. The metal ball formed at a tip of the metal thin wire by an electric discharge is pressure-bonded thermally onto a semiconductor element 6; after that, the metal thin wire 2 is cut from the metal ball. Since a bump 8 which has been pressure-bonded onto the semiconductor element 6 is cut at the constricted part 7 situated between the metal thin wire 2 and the bump 8, it can be formed in a state that the thin wire is not left.

Title: Pulse width measuring circuit
Inventor: YOKOHIRA TAKESHI
IPC: G01R23/10
Filed: 1991-03-18
Abstract: PURPOSE:To continuously measure the pulse width of one cycle by one counter by measuring the pulse width by the reversal and reversal return of a counter control signal due to two one-shot pulse signals different in phase. CONSTITUTION:Fundamental clock signals phi1, phi2 of two phases being clock signals of the same cycle shorter than the cycle of an input pulse signal PS to be measured are inputted to an edge detection circuit 1 and two one-shot pulse signals A, B shifted in phase are outputted in response to the rising of the signal PS. A counter control circuit 2 outputs a count enable signal CE reversed by the phase difference between the signals A, B at each time when the signal PS rises. A counter circuit 3 stops counting by the reversal of the signal CE to output the count value (CONT) of the pulse width of the signal PS and resets CONT by next reversal return to start the counting of a count clock signal (CLK). By this method, a circuit scale is contracted and the control load in software can be reduced.

Title: Disposal of dredged sludge
Inventor: UMIGA NOBUYOSHI
IPC: C02F11/06
Filed: 1980-04-24
Abstract: PURPOSE: To prevent malodor pollution during dredging and to enhance the dehydratability of sludge, by dredging sludge having a low sludge concentration from the bottom of water, reacting with an oxidant such as O 3  or the like, and separating the sludge into oxidizable dredge waste water and oxidation-deodorized dehydrated cake.  
     CONSTITUTION: A sludge layer 3 at the bottom of water is sucked up by the rudder carrier pipe 2 of a dredger 1, and fed 4 under pressure to a disposing boat 5. Dehydrated cake and dredge waste sludge are separated from the sludge in slurry state. A sludge portion having a sludge concentration of from about 30W40%, which is pumpable, to about 10W20%, which means a relatively high water content, is fed 10 under pressure to a disposer. To the sludge being fed 10 under pressure is charged an ozonized gas 11, so that anaerobic water and sludge particles are oxidized by O 3  during the passage of the sludge through a multistage pipe line mixer 12. The sludge is then carried through a gas separator 13 to a coagulating mixing vessel 15, while waste gases containing unreacted O 3  are separted from the sludge by the separator 13, rendered innoxious by a decomposing part 14, and discharged. The oxidized sludge is agitated 16 and mixed with a flocculant in a vessel 15, and carried to a thickener 17 where the sludge is sedimentation-separated into supernatant liquid and thickened sludge.

Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To provide a speaker high in reliability by reducing deformation of a resin frame caused by a generated heat in a voice coil and preventing the position deviation and inclination of a bobbin. SOLUTION: A magnetic circuit 2 is housed in a recessed part 1a formed in the inside of an opening end of a non-magnetic frame 1 and a bottom of a resin frame 3 is fitted and fixed to a guard 11b of the non-magnetic frame 1 and an outer circumferential part of a damper 12 is fixed to the non-magnetic frame 1. Thus, the resin frame 3 is made away from the magnetic circuit by a certain distance to reduce the possibility of deforming the resin frame 3 by heat generation of voice coils C1, C2. Even when the resin frame 3 is thermally deformed, since the thermal deformation does not affect on the mount position of the damper 12, the position deviation and inclination of a bobbin 9 caused by heat generation of the voice coils C1, C2 are avoided.
