Title: Automatic adjusting device of developer density
Inventor: SHIROSUGI KOUJI
IPC: G03G15/10
Filed: 1982-08-16
Abstract: PURPOSE:To perform proper supplementation conforming with the actual condition of a developer and to shorten a waiting time, by controlling a toner supplying solenoid on the basis of toner density when the upper part toner density of the developer is nearly equal to the lower part toner density. CONSTITUTION:When the developer is stirred until the state before a device is stopped, the signal level from a differential amplifier 13 drops below voltages from reference density difference setting parts R7 and R8. Consequently, the 1st comparator 14 outputs an L-level signal to turn off a transistor (TR)15, controlling a solenoid driving TR17. If the density of the developer is less than a set value at this stage, the signal from the 2nd detector 12 drops below the voltages from reference density setting parts R10 and R11, so the 2nd comparator 16 outputs an H-level signal to turn on the TR17, operating the toner supplying solenoid 18 until the toner density attains to the set value.

Title: Composite magnetic head and its production
Inventor: INOUE CHIKARA
IPC: G11B5/133
Filed: 1986-06-18
Abstract: PURPOSE:To obtain a composite magnetic head of high reliability with a good yield by jointing surfaces facing each other of magnetic core half bodies, each of which consists of a sintered block of a pair of thin film-shaped ferromagnetic materials and a ferromagnetic ferrite material, with a nonmagnetic material between them to form a magnetic gap. CONSTITUTION:Metallic cores 11b an 12b and ferrite cores 11a and 12a constituting magnetic core half bodies 11 and 12 respectively are joined like sandwiches by sintering. A gap is not generated in joint parts therefore, and consequently, the magnetic resistance of a magnetic circuit is not increased, and an adhesive layer is not peeled by tape sliding because the adhesive layer does not exist in joint parts exposed on a tape slide face 14 in case of the use, and thus, the composite magnetic head of high reliability is obtained.

Abstract: PURPOSE:To prevent a motor driving level from becoming unstable at the time of starting a motor-driven vehicle. CONSTITUTION:The driver for a motor-driven vehicle of the type for outputting a drive duty signal to drive a motor only when the duty signal exceeds a certain predetermined value sets the predetermined value to a level of an upper limit predetermined value 22 when the signal is in a rising step and to a level of a lower limit predetermined value 23 when the signal is in a falling step.

Title: Production of directional electromagnetic steel plate
Inventor: KAWAOMO YAKICHIROU
IPC: C22C38/00
Filed: 1978-11-22
Abstract: PURPOSE:To economically produce the superior captioned steel plate by rolling the slab blank for the directional electromagnetic steel plate of low C contents to the final plate thickness by a twice cold rolling method of performing cold rolling of the first time at the specific draft or more then subjecting the steel plate to box annealing or open coil annealing. CONSTITUTION:The slab for directional electromagnetic steel plate which is made C0.02% or less in the molten steel stage and is then made to a slab by a continuous casting method or ingot making method is used as a blank. Said blank is rolled to the final plate thickness by a twice cold rolling method in which intermediate annealing is done after hot rolling. At this time, the cold rolling of the first time is accomplished at draft 50% or less to break the texture and microsturcture of the hot rolled plate down to immediate before secondary recrystallization annealing, thereby fining the structure to a moderate degree. Intermediate annealing is accomplished in a decarburizing atmosphere containing wet hydrogen to cause decarburization, thence long-time hot and annealing such as box annealing or open coil annealing is performed after the cold rolling of the second time, whereby the secondary recrystals are stably formed.

Abstract: PURPOSE: To perform dewatering described in the title efficiently and economically, by pouring organic high-polymer flocculant not less than a specific amount excess on the basis of the solid sludge into waste water in order to aggregate and concentrate the sludge through pressure floatation, and by dewatering the concentrated sludge as it is.  
     CONSTITUTION: At the time of concentration through pressure floatation of organic sludge, e.g., the first-sedimentation-pond sludge, surplus activated sludge formed in organic waste-water-treating plant, or a mixt. of these sludges, a cation polymer, which is an organic high-polymer flocculant, not less than 0.3 wt.% excess on the basis of solid sludge, is poured into the waste water in order to aggregate and concentrate the sludge through pressure floatation. I.e., the cation polymer in an amount more than that used in usual pressure floatation concentration, together with cation polymer which is to be used in dehydration of froth, is poured into the waste water. The froth is dehydrated as it is by means of a suitable dehydrator. Because the froth is not diluted with the cation polymer soln. during dehydration, the dehydrator is operated simply without decline in its capacity.

Title: Substrate for synthesizing diamond in vapor phase
Inventor: KURIHARA KAZUAKI
IPC: C30B29/04
Filed: 1988-06-13
Abstract: PURPOSE:To obtain the title substrate for synthesizing diamond in a vapor phase capable of producing a diamond bulk free of release and cracking by mixing quartz glass and a specified ceramic, forming the mixture, calcining the formed product to obtain a glass ceramic, and forming the substrate with the glass ceramic. CONSTITUTION:Quartz glass and a heat-resistant ceramic having an m.p. higher than the synthesizing temp. of diamond and having a thermal expansion coefficient greater than that of diamond are mixed in a specified ratio. The mixture is formed, and calcined to obtain a glass ceramic. The substrate is formed with the glass ceramic. When an oxide such as Al2O3 is used as the ceramic, the mixture can be calcined in the atmosphere. However, the mixture must be calcined in a nonoxidizing atmosphere when a nonoxide such as SiC and Si3N4 is used to obtain an appropriate thermal expansion coefficient. By using this substrate, largearea diamond of about 50mm square can be stably formed without causing cracking and release.

Title: Analog telephone set, exchange and analog telephone set calling method
Inventor: AOKI TOSHIKAZU
IPC: H04W4/20
Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To ring an analog telephone set without supplying a high power signal from an exchange to the analog telephone set in an analog telephone set call method suitable for the use in a private telephone system. SOLUTION: Receiving an incoming call to an analog telephone set 200, an exchange 100 generates a small power encode signal (e.g. a pushbutton signal) to instruct the ringing of a call tone and transmits the signal to the analog telephone set receiving the incoming call. The analog telephone set 200 receiving the signal sent from the exchange 100 decodes the signal to discriminate whether ringing of the call tone is instructed. The analog telephone set 200 that detects the instruction for ringing a call tone outputs a call tone signal to a speaker section 230.

Title: Capacitor
Inventor: MIZUKAMI MASATO
IPC: H01G4/38
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To provide a small capacitor which can be assembled easily. SOLUTION: Plural elements 1 and plural separators 7 comprising a laminated body of a metalized film or a metalized film and a dielectric film are alternately laminated, while being so allocated that one end of the separator 7 is protruded above an element end surface, in the film width direction of the element, and the other end on the same plane of the element end surface or inside of it. Thus a metal which is melt-sprayed on both sides of the element end surface is separated by the element 1 on the one end side of the separator 7, while an identical pole continuously across the elements 1 on the other end side is formed. This element group is housed in a jacket case 4 and filled with a filler. Thus, a wire-connection works with lead wires 3 of the identical pole is fewer and the handling of the element group is easy, for the easy assembly work of a capacitor. Further, insulation among plural elements 1 is easier, while they cross among others, for miniaturizing of a capacitor.
