Title: Scale recording method for recording chart
Inventor: SHIRAHATA ATSUSHI
IPC: G01D3/02
Filed: 1981-12-16
Abstract: PURPOSE:To record the directly read scale of voltage units automatically by measuring the dynamic range of input voltage and the amplifier gain set in accordance with the width of recording chart by using a variable attenuator and recording the scale voltage corresponding to the input voltage. CONSTITUTION:The analog voltage to be recorded is connected to the stationary contact 31 of a switch 3, and the output voltage of a variable attenuator 8 is connected to the stationary contact 32. A movable contact 33 is connected to the contact 31, and the gain of an amplifier part 1 is so set that the width of recording chart is usable effectively for the dynamic range of the input voltage. The recording chart is recorded theron with a pen driving part 2. Upon ending of the recording, the contact 33 is connected to the contact 33 and the gain G0 of the amplifier 1 is measured. A comparator 5 compares a voltage 4 and a standard voltage 6, and can determine a gain G0 by controlling the attenuation factor of the attenuator 8 with a controller 7. The attenuator 8 is so constituted as to input the output of a variable numerical value generating circuit to a multiplier. Further the value of the numerical scale value is calculated and applied by using the gain G0, whereby the directly read scale of the voltage units is recorded.

Abstract: PURPOSE:To make possible the formation of a roughness, by which the reflection of light is reduced, by a method wherein a boron oxide is coated on one main surface of a substrate and the diffusion of boron is performed in the substrate while halogen gas is supplied in an inactive atmosphere. CONSTITUTION:Ethylene glycol monoether, in which a boric acid is dissolved, is coated on one main surface of a p-type poly Si substrate 1 and is dried to form a boron oxide coat film 2. Then, a heating treatment is performed in a nitrogen gas-containing atmosphere to react the film 2 with silicon and to form a borosilicate glass 3. Moreover, halogen gas, such as chlorine gas, is supplied in an atmosphere containing chlorine and nitrogen and the other main surface, which is not covered with the glass 3, of the substrate 1 is subjected to vapor phase etching with the chlorine gas. After this, the supply of the chlorine gas is stopped and a high-temperature heating treatment is performed in a nitrogen gas-containing atmosphere to form a surface roughness 5 and a boron diffused layer (a p<+> layer) 4. Thereby, the surface roughness, by which the reflection of light is reduced, can be formed using the low-cost substrate.

Title: Magnetic bubble memory device
Inventor: YAMADA TADASHI
IPC: G11C19/08
Filed: 1983-10-31
Abstract: PURPOSE:To prevent an arbitrary stop of a magnetic bubble device during an access by discontinuing the actuation of the bubble device after the end of an access in case the bubble device has an abnormality during said access. CONSTITUTION:The OR processing is carried out between a high-level abnormality detecting signal 16 produced when a magnetic bubble memory device 5 has an abnormality during an access and a high-level magnetic bubble transfer signal given from a device control circuit 2. Then the production is controlled for a low-level magnetic bubble stop signal 18, and this signal 18 is supplied to the circuit 2 as a power-down signal. Therefore the device 5 is stopped after the access is through with the circuit 2. This prevents an arbitrary stop of the device 5 during an access. Thus it is possible to finish satisfactorily the actuation of the device 5 in response to its access in case an abnormality occurs owing to a temperature change which takes a long period of time to give its effect.
