IPC: H05K3/12
Filed: 1994-08-25
Abstract: PURPOSE: To obtain a metallized board wherein a metallized layer excellent in flatness wherein no voids are generated and the thickness of a conducting metal layer is greater than a specific value is formed, by using a screen pattern having no linear edge ends rectangular to the travelling direction of a squeegee. CONSTITUTION: The pattern edge end portion (line type) of a screen pattern makes an angle of 45 deg. to the squeegee direction. The sectional structure of resist 2 has an inclination of 10 deg. in the direction of resist thickness. Thereby the contact area of the pattern end portion can be reduced, and it is possible to reduce the supply of paste to the end portion, so that the surface tension can be reduced. By using the screen pattern, metal paste composition is spread one time on the surface of a ceramics board and dried. Thus a metallized layer is formed 250μm thick. A metallized ceramic board can be obtained by heat treatment in a high vacuum or an inert gas atmosphere.

Title: Refrigerator
Inventor: UEDA KAZUHIRO
IPC: F25D11/00
Filed: 1987-09-09
Abstract: PURPOSE: To keep the degree of freshness of a fresh food case in a food freezer having a plurality of evaporators by a method wherein a control section of the freezer controls another control section so as to throttle a throttling device corresponding to an evaporator other than a specified evaporator when the temperature of an object to be cooled becomes higher than a predetermined temperature under the specified evaporator. CONSTITUTION: When the refrigerator temperature of a fresh food case becomes higher than a specified temperature, e.g. 2 deg.C or more under a defrosting operation and the like, a second controller 3-7 outputs a signal to the first controllers 4-7, 5-7, respectively, and reduces the degree of opening of a valve in each of the throttling devices 4-2, 5-2 by 1/2. As a result, since the entire resistance of a refrigerant circuit is increased, it is operated such that the pressure on the low pressure side of it is decreased, the evaporating temperature is decreased and a heat exchanging amount at an evaporator is increased. As a result, the degree of opening of the metering device 3-2 for an evaporator 3-1 is increased, the flow rate of refrigerant is increased and the cooling capability is increased. In this way, it is possible to maintain the freshness of food.

Title: Print test control method for printer
Inventor: ABE TOMONORI
IPC: B41J29/46
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To reduce the occupancy rate of a control program for print test by executing print processing and center skip processing by a number of times corresponding to a number of pages designated by number of page designation processing. SOLUTION: In a print test for a booklet, e.g. a bankbook, center skip processing is executed upon recognizing the end of printing on an upper page. An idle feeding amount being performed at the binding of a booklet medium is two lines for the line feed pitch of 1/5 inch and three lines for the line feed of 1/6 inch. Two lines are fed idly and unconditionally at first (S20) and a decision is made whether the line feed pitch is 1/6 inch or not (S21). It is left as it is when the decision results are negative and the operation is ended after feeding one more line when the decision results are positive (S22) Since the idle feed operation is performed based on print parameters, significant modulation of the control program is not required even if the line feed pitch or the number of print lines is altered.

Title: Limiter circuit
Inventor: DOI KOJI
IPC: H03K5/1252
Filed: 1989-08-30
Abstract: PURPOSE:To exclude impulse noise by detecting codes of two points close to each other, and operating a flip-flop depending on the logic. CONSTITUTION:The circuit consists of a delay circuit 1, code detection circuits 2, 3 and a flip-flop 4 and the delay circuit 1 is set to retard an input signal larger than the pulse width of noise to be assumed. The code detection circuit 2 detects the polarity of the input signal to output a logic value and the code detection circuit 3 detects the polarity of the output signal of the delay circuit 1 to output a logic value. The flip-flop 4 latches an output value when both the output values of the code detection circuits 2, 3 are coincident and latches a preceding value when they are dissident. Thus, even when impulse noise is included in the input signal, the zero cross point of the input signal is accurately detected without being affected thereof.
