Title: Manufacture of metallic siding and device therefor
Inventor: GASSHO YASUSHI
IPC: B29C39/24
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To remove a resin which undergoes a chemical reaction during production and avoid the suspension of production for replacement of a spatula by blowing air to a foamable reaction mixed product which is pending non-chemical reaction immediately after supply thereof on a lower-side base material and spreading the foamable reaction mixed product over the lower-side base material and at the same time, removing foam contained in the reaction mixed product. SOLUTION: Air is uniformly blown, in the lateral width direction from an air blow hole 7b of a nozzle 7a arranged obliquely upward in the downstream, to a foamable reaction mixed product 6b whose chemical reaction is not yet underway after it is supplied from a mixer 6a, on a lower-side base material (a) being transferred in the fixed direction, and then is uniformly spread in the lateral width direction of the lower-side base material (a). At the same time, the foam contained in the foamable reaction mixed product 6b is dispersely removed to the outside, and immediately after that, an upper-side base material (b) is supplied from above and the whole materials are transferred to a heating/pressurizing means 11 as a next step to shape the whole materials to the specified form. This form is unloaded as a finished product.  Thus it is possible to make the hole-free homogeneous form and dispense with the operation to remove the resin which undergoes a chemical reaction during production and replace spatulas, so that the production can be continued without interruption.

Title: Discharge-lamp lighting device and discharge lamp device
Inventor: MITA KAZUTOSHI
IPC: H05B41/24
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To provide a discharge-lamp lighting device reduced in size, by lighting a burden on a capacitor for direct current blocking. SOLUTION: A fluorescent lamp FL is started up by producing resonance with a resonance inductor L2 and a resonance capacitor C4. When the fluorescent lamp FL is lit, a capacitor C6 for direct current blocking is charged and a lamp-lighting abnormality detection circuit 6 judges the lighting to be normal, causing a switching circuit 3 to output a normal voltage. When the fluorescent lamp FL comes to its life-ending stage and half-wave discharge takes place, the lamp-lighting abnormality detection circuit 6 detects it and outputs a safety signal to lower the voltage of the switching circuit 3.  The resonance current is prevented from flowing through the capacitor C6 for direct current blocking by connecting the capacitor C6 for direct current blocking in parallal with the resonance capacitor C4, and thereby the capacitor C6 for direct current blocking can be made lower in cost and smaller in size.

Title: Oscillating circuit
Inventor: ERUNSUTO HIYUUGO NORUDOHOORUTO
IPC: H03B5/32
Filed: 1988-12-28
Abstract: PURPOSE: To improve the starting characteristic of a circuit by attaining the stepwise switching of a bias current source through a level detector for stepwisely exciting a resonance circuit with a predetermined potential at a power supply terminal. CONSTITUTION: When a voltage at an input terminal 8 of a comparator 7 exceeds a threshold voltage at an input terminal 9, a trigger signal is immediately supplied to a trigger circuit 6, and this trigger circuit supplies a stepwise excited signal to an amplifier circuit 1. As a result of this stepwise excited signal, the quantity of energy for resonating a crystal resonator 3 is suddenly supplied to this crystal resonator. A threshold voltage Vd at the input terminal 9 of the comparator 7 is determined by the value of a power supply voltage VB for letting the amplifier circuit 1 reach setting with which a resonate signal can be generated. Thus, a loop gain is lowered and the noise characteristics of an oscillation circuit is improved.

IPC: G01F1/00
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To extremely extend a flow measuring interval without reducing flow measurement accuracy and to further reduce power consumption. SOLUTION: In this flow measuring method, the pressure in a passage 10 detected by a pressure detecting means 16 is invariably monitored by a first pressure detecting means 14a-1 intermittently.

When the first pressure detecting means 14a-1 detects that the pressure becomes unstable, a second passing flow measuring means 14a-3 measures the passing flow of the fluid passing the passage while the pressure is stabilized.  When the first pressure detecting means 14a-1 detects that the pressure becomes unstable, the second passing flow measuring means 14a-3 intermittently measures the physical quantity changed in response to the flow velocity of the fluid with the measuring device 1, and the passing flow of the fluid passing through the passage is intermittently measured at each measurement during the period when the pressure becomes unstable.
