Patent JP-H06224708-A (JP)
Title: Pulse width modulation circuit
Inventor: NAGAMINE TAKU
IPC: H03K5/04
Filed: 1993-01-27
Abstract: PURPOSE:To attain a high speed operation of the circuit by selecting which delay circuit having a delay time to be used among delay circuits connected in series based on parallel data. CONSTITUTION:An input bit D0 is applied to an AND gate 102 directly and inverted by an inverter 104 and the inverted bit is fed to an AND gate 103. A carrier signal as an input pulse from an input terminal 5 is fed to a delay circuit 101 and the AND gate 103. Thus, when the D0 is logical 1, the bit is inputted to the gate 102 and the delayed signal is outputted from an OR gate 105. When the bit D0 is logical '0', it is inputted to the gate 103 and a signal not delayed is outputted. Since the delay time of delay selection circuits 101-10n is decided depending on the weight of received data bits D0-Dn, a delay time T of the pulse outputted from the final stage circuit 10n is proportional to the parallel data D. An FF 7 is set by a carrier input and reset by a signal whose delay time is T and a pulse signal with a pulse width proportional to the data D is outputted.

Title: Substrate for semiconductor device
Inventor: YAMAGISHI RYOZO
IPC: H01L21/60
Filed: 1985-02-18
Abstract: PURPOSE:To obtain the titled substrate of markedly low cost which is easily produced with junction secured between a copper foil and a flexible insulation film, by a method wherein the adhesion surface of the copper foil adhered to this film is provided with a gloss copper plated layer. CONSTITUTION:After pre-treatment of a rolled copper foil tape 2, a 4mum gloss copper plated layer 15 is applied to it out of a copper cyanide bath. Thereafter, this is slitted by a 27mm-width and adhered to a 35mm-width polyimide film 1 with an adhesive 14 into a film carrier. Use of a copper foil provided with a gloss copper plate layer on the surface adhered to the flexible insulation film gives a necessary degree of adhesion with this film; besides, even when tin, solder, or silver plating is not done after the fine pattern processing of the copper foil, good junction can be obtained at the lead part of the copper foil in a reductive atmosphere. As a result, it is possible to omit treatments such as coarsing the copper foil adhered to said film, oxidizing it after adhesion, and plating it after patterning.

Title: List memory
Inventor: YAMAMOTO MASAHIRO
IPC: G06F9/44
Filed: 1982-02-26
Abstract: PURPOSE:To obtain a list memory incorporating a means to supply list cells rapidly, by marking the list cells and taking the list cells in advance. CONSTITUTION:When a list cell requesting signal 208 is sent from an external device, the tag parts of the list cells are read out in the tag parts of a cell address register 21 through a signal line 204 by changing the lower 10 bits of the cell address register 21 from ''0'' to ''1023''. In every reading-out of one word, a signal line 209 discriminates whether the tag part is ''0'' or not and finds out a list cell which has been initially turned to ''0''. When a list cell of which tag part is ''0'' is detected, the tag part of the list cell in the memory cell is set up to ''1'' and the memory address is set up in the upper 6 bits of the cell address register 21 through a signal line 210. Subsequently the cell address of the cell address register 21 is outputted to the external device through a signal line 206.

Title: Contrast enhancement material for pattern formation
Inventor: ENDO MASATAKA
IPC: G03F7/095
Filed: 1987-02-12
Abstract: PURPOSE:To permit formation of an extremely fine resist pattern with high accuracy without having defects and without lowering throughput by using a photoreaction reagent having a substituent only in the ortho position and para position with respect to the diazo group of a diazonium compd. having a benzene ring. CONSTITUTION:The photoreaction reagent having the substituent only in the ortho position and para position with respect to the diazo group of the diazonium compd. having the benzene ring is used. Since the fading property reagent of the diazo system is soluble in an aq. soln., the initial transmission is small and since fading is liable to arise, the transmittance after exposure increases and the effect of contrast enhancement is improved. Formation of the extremely fine resist pattern is thereby permitted stably with high contrast, high resolution and high accuracy with substantially no degradation in the throughput.

Title: Linear pulse motor
Inventor: MURAYAMA HIROKI
IPC: H02K41/03
Filed: 1987-02-12
Abstract: PURPOSE:To enhance the reliability of a linear pulse motor by enclosing the pole of a primary core with a nonmagnetic material, and constructing to form it in the same plane as the pole teeth of the core. CONSTITUTION:The primary core 10 of a linear pulse motor is composed of 4 poles 11, and a permanent magnet 12, and the periphery is enclosed with a nonmagnetic material 13. The surfaces of the material 13 and the secondary core of the pole 11 are simultaneously polished in the same plane, and pole teeth responsive to a step pitch are formed at the pole 11. Since the secondary core is formed larger than the region formed with the material 13, as the secondary moves, the pole 11 of the primary core is not contacted with the atmosphere except the intermediary of an air gap between the primary core and the secondary core. Thus, dust particles larger than the air gap length can be prevented from invading to the interior at the air gap between the material 13 and the secondary core.
