Title: Manufacture of semiconductor device
Inventor: NAKATANI MASAHIRO
IPC: H01L21/265
Filed: 1991-10-09
Abstract: PURPOSE:To provide a method for manufacturing a semiconductor device having an accurate resistance. CONSTITUTION:After a SiO2 film 4, an Si3N4 film 7 arid a CVD SiO2 film 17 are sequentially formed on a p-type Si substrate 1, the film 17 is selectively removed to the surface of the film 7 to form a groove. A polysilicon film 8 is buried in the groove 18. Ions are implanted with an implanting mask 5 having an end at a position separated l-2mum from the film pattern 8 to form a polysilicon resistance layer. Thus, an ion beam amount to irradiate resistance layer 8 is made uniform in the surface of a wafer. Thus, an irregularity in a resistance value can be suppressed to provide an accurate device.

Filed: 1993-09-24
Abstract: PURPOSE:To attain the continuous input of output signals through a terminal equipment even when the supply of power is stopped from an external equipment by monitoring the output signal of the terminal equipment and starting the supply of power to the terminal equipment in place of the external equipment that has stopped the supply of power. CONSTITUTION:When a power switch is turned on by a user, a control circuit 8 outputs the channel selection data to a high frequency processing circuit 7 while the supply of power is disconnected to a down comparator 3. Then the circuit 8 monitors the output data of an A/D converter 17 and decides whether a satellite broadcast channel is received by some reception frequency. When the output data of the converter 17 rise on value O, the circuit 8 decides that some channel has been received. Thus the circuit 8 selects a desired channel in response to the channel selecting operation of the user without starting a power circuit 18.

Title: Rubber blanket for printing
Inventor: SONOBE SABURO
IPC: B41N10/00
Filed: 1986-11-05
Abstract: PURPOSE:To enhance the reproducibility of dots and the releasability of paper, by a method wherein a rubber surface layer made of a kneaded-type urethane rubber having a specific surface roughness is provided on the surface of a substrate. CONSTITUTION:To enhance the intrinsic printing qualities of reproducibility of dots and uniformity of solid, it is preferable that a rubber surface layer is made to be as fine in surface roughness as a plate surface. If the rubber surface layer of a kneaded-type urethane rubber is used, a sufficient paper- discharge force can be exhibited even with a surface roughness lowered to the order of 0.5 mum; the paper discharge layer can not be sufficiently improved and a printing quality is remarkably deteriorated with a surface roughness increased to 2 mum or over. Therefore, the rubber surface layer made of a kneaded-type urethane rubber of 0.5-2 mum surface roughness is formed in such a manner as that, in the production of a rubber blanket, a extremely smooth plastic film is applied to the rubber surface and vulcanized and, thereafter, it is peeled off, or alternatively the rubber surface is vulcanized and, thereafter, abraised with a sand paper of very fine-particle surface.
