Title: Shadow mask
Inventor: KIKUCHI KATSUAKI
IPC: C23F1/00
Filed: 1979-04-25
Abstract: PURPOSE:To obtain a picture image having no color shift or flickering, by employing a material having high attenuation for the shadow mask itself thereby forming the shadow mask not to be a curved face but a planar shape. CONSTITUTION:Stainless steel or aluminum alloy is employed for the shadow mask to elute the crystal particle at the superficial section or the material existing along the proximity, to produce a porous superficial section having vibration-proof function. Since the transient vibration characteristic shows good attenuation and the shadow mask body can have planar shape, the curving face work isn't required resulting in the improvement of the accuracy.

Title: Constant voltage output circuit
Inventor: TAKAHASHI HIROYUKI
IPC: H02M7/06
Filed: 1990-03-01
Abstract: PURPOSE:To prevent a power factor from lowering by detecting the output current of a rectifier circuit, and stopping the supply of an on-pressing signal to a switching means when detecting a current exceeding a preset level. CONSTITUTION:Detecting means 27, 21, 22, and 24 detect the output current of the rectifier circuit 5 i.e. an input current i1p to DC-DC converters 6-9, and when it exceeds the preset level Vref, peak suppression means 23, 25, and 28 stop the supply of the on-pressing signal ton to the switching means 8. Therefore, no excessive current peak at the peak part of an AC power source flows on the DC-DC converters 6-9. Thereby, no input current exceeding the upper limit flows on the DC-DC converters 6-9, and also, the envelope value of the input current is limited in moderate sine wave shape, and the power factor of the input current can be maintained in the neighborhood of 1, and no remarkable lowering of the power factor occurs.

Patent JP-H0347217-A (JP)
Title: Cutting device for hand-wiping material
Inventor: MOORISU GURANJIE
IPC: A47K10/36
Filed: 1990-03-01
Abstract: PURPOSE: To make it possible to cut a material strip easily and in a shearing fashion by devising the metal blades so that they gradually come to an overlap with each other from one end to the other and during a period of turning and that they are kept substantially on a parallel position with the turning axis of the gear pairs throughout the cutting operation. CONSTITUTION: Since while the two blades 5, 6 are normally faced to each other, the cutting edge of the blade 6 gets a contact or near-contact with the cutting edge of the blade 5, the blade ends at the sides of gears 1, 3 overlap with each other. The projection 5b of the blade 5 then gets a contact with the recess 11a of the connecting rod 11. Since the hinge pin 12 position is correctly calculated, the connecting rod 11 is forcibly pressed onto the blade 5 turned by a force manually pulling its projected strip, thus, being turned against the spring 13, and when the protrusion 5b of the blade 5 touches, it is held in line with the axis, supporting the driven blade 6 as well. The spring for the blade 5 is calibrated so as to add a pressure onto the blade 6 during a period of cutting.  This cuts progressively the strip via the warped profile of the blades from one end up to the other end.

Filed: 1995-03-10
Abstract: PURPOSE: To provide a high contrast difference by integrating a primary differentiated output image pickup signal from a solid-state image pickup element for one field period and controlling exposure so as to maximize the dynamic range of an image signal in one pattern. CONSTITUTION: An image pickup signal is given to an A/D converter, from which digital image data ID are given to a delay means 101. The means 101 delays the image data by sampling the data by one picture element. Then a primary differentiation means 102 calculates an absolute value between image data for one picture element sampling period at a current time and the delayed and sampled image data. The output signal of the means 102 is integrated by an integration device 103 for one field period and the integrated signal is outputted to a delay means 104 and a comparator means 105. The means 104 delays the integrated signal for one field period and provides the output to the comparator means 105. The means 105 compares the integrated value of the integration signal delayed by one field with the integrated value of the integration signal not delayed.  When the former integration value is higher, the control signal of an H level is outputted to the means 106 to inform reversed exposure control to the means 105. When it is discriminated t,hat the control method is correct in the case that the former integrated value is smaller and the exposure control is continued.

Abstract: PURPOSE:To surely prevent oils from being mixed and overflowing by a method wherein a judging device, which is mounted on a tank lorry and judges whether oil types are consistent based on an oil type signal in a tank to be supplied with oil and a signal for opening a hatch valve of the tank lorry, and an alarm means which informs the inconsistency of the above are provided. CONSTITUTION:When a bottom valve V1 of a lorry R is opened, a signal for opening the valve is input from a bottom valve sensor 8a to a control device mounted on a truck, and a judging device compares this signal with a type of oil in a hatch H1 and an oil amount, and with an oil type of tank T1 which is temporarily memorized in a storage 17 and a space amount. If the type of oil is correct and the amount of oil is sufficient, a main valve 9 is opened to supply oil, and the main valve 9 and the bottom valve V1 are closed when supplying is completed. If the type of oil is not correct, a control signal is output from an informing member 19 to operate an alarm 20 to inform the difference with a strong alarm sound. Then the bottom valve V1 is closed, a coupling 11 is removed from an oil inlet port 4a and joined to another oil inlet port 4b or 4c. If the type of oil is now correct, the alarm 20 stops sounding.
