Title: Method and apparatus for dicing
Inventor: ISHIGAKI KOJI
IPC: H01L21/301
Filed: 1996-01-24
Abstract: PROBLEM TO BE SOLVED: To eliminate returning time loss of a blade by dicing a semiconductor wafer while turning the blade such that the dicing direction is directed downward on both forward and returning paths of relative movement. SOLUTION: A cut line 4 is formed on a wafer 1 along a scribe line 3 at the time of cutting the wafer 1 by means of a blade 19. More specifically, at the time of cutting on the forward path, the blade 19 is turned while directing the cutting direction downward thus down cutting the wafer 1. At the time of cutting of the returning path, the blade 19 is carried in the direction of the forward path after the rotary shaft 18 is inverted by 180 deg. thus cutting the wafer 1. In other words, the blade 19 is turned while directing the cutting direction downward at the time of cutting on the return path thus down cutting the wafer 1. According to the method, return time loss of the blade 19 can be eliminated while sustaining the good cutting state.

Title: Warning system
Inventor: SHIMIZU HIROKIMI
IPC: B41J29/48
Filed: 1980-03-10
Abstract: PURPOSE: To inform the end of recording paper without the needs for special communicating means by using a system in which the residue of recording paper in a recording type electronic instrument is detected, and when the remaining runs short, the driving signal of a display mechanism is changed.  
     CONSTITUTION: For example, when a rolled recording paper 1 runs short, reflecting light from a light emission diode 3 fails to go into a photo transistor 4, and AND gate 9 goes ON. When a coloring command signal is input, pulse width signal is generated from a monostable multi-vibrator 5. On the other hand, since AND gate 9 is ON, trigger from a delay circuit 6 passes through OR gate 10 and then is put in the monostable multi-vibrator 5 as retrigger, whereupon large pulse is generated and then sent out to a display tube driving circuit. The display tube emits light in proportion to the pulse width, and when the residue to the recording paper 1 runs short, the lowest luminance of the fluorescent display tube is higher to indicate the end of the recording paper.

Abstract: PURPOSE:To facilitate maintenance and to enable the use of a curable binder and pigment, by heating a recording solution by irradiating the predetermined part of a film with laser beam and selectively emitting and flying the recording solution in minute recessed parts. CONSTITUTION:A recording solution is applied to a film having a large number of minute recessed parts to be supplied to the recessed parts and the film is irradiated with laser beam corresponding to an input signal to heat the recording solution in the recessed parts and said recording solution is emitted and flawn to a recording material from the minute recessed parts by the thermal expansion of the recording solution due to heating or energy due to the evaporation of the recording solution. Recording is performed by emitting and flying the recording solution in the minute recessed parts of the film only at necessary parts and the recording solution can be supplied only by again applying the recording solution to the surface of the film. That is, safe pigment and a resin can be used and printed matter excellent in solvent resistance can be obtained and the clogging due to the recording solution is extremely hard to generate and, even if clogging is generated, the washing and replacement of the film can be easily performed.

Filed: 1981-03-03
Abstract: PURPOSE:To answer without delay by a regular current waveform without answering by a spike current component of an input current waveform, by comparing the reference voltage on which differential voltage of detection voltage has been superposed, with the detection voltage. CONSTITUTION:A detection current transformed by a transformer T1 is shunted by resistnaces R1, R2, and a voltage waveform almost similar to a current waveform is generated across the resistance R2. This voltage waveform is applied to not only one input termianl of a comparator CP but also a differentiating circuit constituted of a capacitor C3 and a resistance R3, and to the reference side input terminal of the comparator CP, superposed reference voltage obtained by superposing the differential voltage on the reference voltage is applied. In this way, even if input voltage has been raised by a spike current component of the input current waveform, input voltage of the reference side is also raised in accordance with said rise, and the comparator is capable of exactly detecting an overcurrent without answering by the spike current component.
