Title: Printed-wiring board and manufacture thereof
Inventor: SAKUYAMA SEIKI
IPC: H05K3/28
Filed: 1992-10-27
Abstract: PURPOSE:To avoid the solder bridging between nearby pads by a method wherein a solder resist layer in the thickness larger than that of conductive layers in the near central part between pads getting thinner as near as the terminals thereof is to be formed on the insulating surface between the terminals. CONSTITUTION:The sectional shape of a solder resist layer 20 provided between the pads 3 of a wiring pattern arranged on an insulating substrate 1 is made to be the thickest in the central part getting thinner as near as the pads 3. Especially, the maximum thickness is to exceed three times of the thickness of conductive layers comprising the pads 3 in the contrete exceeding 100mum. Through these procedures, the solder bridging between the pads 3 can be avoided almost perfectly. Due to the formation of the resist layer 20 in such a thickness distribution, the exposure amount to photoresist can be fluctuated corresponding to this thickness distribution within the range from the saturated exposure amount to the amount not exceeding the same.

Filed: 1988-11-17
Abstract: PURPOSE: To improve safety by forming a reflector so that light will be reflected back into other portions of the reflector by ridges and grooves formed on a flat lower surface of the reflector. CONSTITUTION: A surface having a structure including a series of ridges and grooves, such as ridges 32, 34 and grooves 36, 38, is installed in piles on a flat surface 20 of a reflector housing 10. Consequently, a ray 40 is reflected on a ridge 32 and turned into a reflected ray 42 and then directed back into the reflector housing 10. After another reflection by the reflector housing 10, the ray 42 is turned into a beam 44 and goes out from an optical cavity 14 through an optical window 12 to the similar direction as the direction of a main beam paralleled to the horizontal direction. Consequently, the light, hitting on the flat bottom surface of the optical cavity 14, receives multi-reflective functions, to thereby remove dangerous vertical direction components before going out from the optical cavity 14.

Title: Work-rotating type grinding wheel cutting method
Inventor: FUJISAWA MASAYASU
IPC: B24B27/06
Filed: 1987-11-18
Abstract: PURPOSE:To cut work easily without generating a recess on the surface of the work to be cut by a method wherein the rotation of the work is stopped and a core is cut when the diameter of the core has become a predetermined value. CONSTITUTION:A cutting grinding wheel 7 and an ingot 3 are rotated clockwise until the diameter of a core 4 has become a predetermined value, then, the ingot 3 is fed upward to cut the ingot 3. Next, the cutting grinding wheel 7 is rotated and the rotation of the ingot 3 is stopped, then the ingot 3 is fed to cut the core 4. Accordingly, torsional force will never be applied on the core 4, therefore, the core 4 will never be broken in a surface, slanted against the center line of the ingot 3, whereby any recess will not remain at the central part of a wafer 1. Further, the cutting surfaces of the ingot 3 and the wafer 1 are ground by the side surface of the cutting grinding wheel, therefore, warpage on the cutting surface of the wafer 1 may be reduced and the surface roughness of the cutting surface of the wafer 1 may be greatly improved.

Abstract: PURPOSE:To simply obtain the multiplex constitution of a control device and to obtain a process control device having extremely high reliability by finding out AND operation between the output of a peak detecting circuit and a diagnosis command signal, inputting the AND result to a pulse generating circuit and outputting a command pulse. CONSTITUTION:A diagnosis command signal 4B from an arithmetic operation part 4 in each of control devices 1A, 1B is supplied to an AND circuit 6, AND operation between the signal 4B and an output from the peak detecting circuit 5 for detecting the positive or negative peak of an AC driving power supply 10 is executed by the circuit 6 and the AND result is inputted to a pulse generating circuit 7. Each of switching circuits 3A, 3B is turned on/off by a command pulse outputted from the circuit 7. Since the inputs to the circuits 7 are AND signals between the signal 4B and the output of the peak detecting circuit 5 for the power supply 10 common with the devices 1A, 1B, the timings of both the inputs coincide with each other and the outputs of the circuits 7 and the switching circuits 3A, 3B are simultaneously turned on and off. Thus, the duplication of the control device can be obtained by means of a simple constitution by only adding an AND circuit.
