Patent JP-S6154515-A (JP)
Title: Dc stabilized power supply device
Inventor: NAKAMURA KEIICHI
IPC: G05F1/56
Filed: 1984-08-23
Abstract: PURPOSE:To reduce the loss power of a control transistor (TR) as well as the internal loss of a power supply by comparing the stabilized output voltage with the reference voltage to control continuously the conduction degree of the control TR. CONSTITUTION:The terminal voltage Vin of a capacitor 14 rises up when the voltage of a commercial AC input terminal 11 reaches its upper limit level. Then the voltage also rises up at a point A together with the stabilized voltage Vout. When the input voltage is lowered down to its lower limit level, the voltage Vin is also reduced. This lowers the voltage at the point A. Here if the current to be supplied to a load circui 19 increases, the current flowing through a control TR15 also increases. Then the voltage of the point a has no fluctuation despite the fluctuation of a load current, and only the input voltage has fluctuation. As a result, the collector-emitter voltage of the TR15 does not increase regardless of the upper limit level of the input voltage. This can prevent the increase of loss of the TR15.

Title: Coffee bean powder distributing method and apparatus in coffee brewer
Inventor: HANSUUPEETAA FURAI
IPC: A47J42/40
Filed: 1984-08-24
Abstract: A coffee machine includes a grinding mill, a proportioning chamber arranged adjacent to the outlet of the grinding mill and a processing chamber, into which the coffee powder from the proportioning chamber is discharged. The coffee powder coming from the grinding mill is thrown into the proportioning chamber, which includes a pressure sensitive, elastically resilient wall element with a signal generator connected thereto. As soon as the proportioning chamber is filled with coffee powder, a dynamic pressure is built-up within the proportioning chamber due to the overpressure caused by the grinding mill, which forces the wall element to a displacement, whereby the signal generator is operated. Subsequently, on the one hand, the motor of the grinding mill is switched off and, on the other hand, a bottom wall part of the proportioning chamber is unlocked, whereby the milled product, assisted by the elastically resilient wall element, is discharged from the proportioning chamber.

Abstract: PURPOSE:To shorten the power supply ON/OFF time and to simplify the control of a power controller by delaying the power ON/OFF operation in accordance with the delay time set when a power ON/OFF instruction is received from the power controller. CONSTITUTION:When the power supplies are sequentially applied to the information processors (1-1) - (1-n), a power supply application signal delay circuit 32-n outputs a power supply application signal 111-n to a DC power source generating part 31-n when (l1 +... + ln-1) seconds passed after a power supply application signal 112-n is inputted from a power supply application signal receiving circuit 34-n because (l1 +... + ln-1) seconds are set to a power supply application delay time setting switch 33-n of the processor 1-n. Thus a DC power source is supplied to a power supply line 110-n from the part 31-n, and the power supplies are applied to all processors 1. As a result, the power supply ON/OFF time is shortened and the control of a power controller is simplified.

Filed: 1994-07-29
Abstract: PURPOSE:To provide a transmittance modulation type photomask which is easily producible while having the performance equivalent to the performance of the conventional photomasks and a process for production thereof and an optical element formed by using the same. CONSTITUTION:A light absorption layer 3 having absorptivity to light of a prescribed wavelength region is formed on at least one surface of a substrate 2 for the photomask which is substantially plane on both surfaces and is substantially transparent to light of the prescribed wavelength region. This light absorption layer 3 is formed to a shape having a prescribed depth distribution. As a result, the transmittance of light is given according to the depth distribution when the light of the prescribed wavelength region is transmitted through this layer. The transmittance of the light is higher at the points where the depth is deeper and the transmittance of the light is lower at the points where the depth is shallower and, therefore, this photomask acts as the transmittance modulation type photomask 1. The photomask is more easily producible than the photomask formed with the prescribed shape on the substrate itself for the photomask.

Title: Multiple cylindrical winding
Inventor: ISAKA SUSUMU
IPC: H01F27/28
Filed: 1987-07-17
Abstract: PURPOSE:To obtain a multiple cylindrical winding, in which specified inter-layer insulating size and oil ducts are formed among each cylindrical winding and winding work of which is facilitated while a winding space factor and cooling characteristics of which are further improved, by arranging wedge-shaped duct pieces consisting of a plurality of tapered insulators among the cylindrical windings in respective layer. CONSTITUTION:A plurality of duct pieces 6 consisting of press boards are installed in the circumferential directions of windings among each layer in a plurality of concentrically disposed cylindrical windings 1a-1g, and the winding of the windings and the arrangement of the duct pieces are repeated alternately extending over multilayers. Consequently, the upper section of the duct piece can be wound in the axial direction of the winding on the reverse side continuously without cutting a conductor in the cylindrical winding 1b in the next layer. Since the layers of inter-layer insulators having a large dielectric constant are removed, equivalent insulating size among layers is not scaled down, and electric field stress at winding ends is minimized and the size of an oil duct 4 can be reduced. Since both side faces of a cylindrical winding 1 are brought into contact with a refrigerant, the cooling efficiency of the windings is made double as large as conventional devices, thus inhibiting the temperature rise of the windings at a low value.
