IPC: H01J23/26
Filed: 1994-01-12
Abstract: PURPOSE:To suppress bending of a helix at a junction point of each vacuum vessel unit, facilitate its design, and simplify its manufacturing process by differentiating the position of the dividing point of the vacuum vessel from that of the helix. CONSTITUTION:Two vacuum vessel units 13a and 13b with roughly equal axial length in which pole pieces 11 and spacers 12 are alternately junctioned with air-tightness are formed and their inner diameters are precisely processed. Next, helixes 14a and 14b divided in lengths different from each other are supported and fixed by means of inductive support bars 15a and 15b divided in different lengths from the other. Units 13a and 13b are junctioned with air-tightness by means of a welding 16, etc., and a vacuum vessel 13 is formed. Finally, the helixes 14a and 14b and the support bars 15a and 15b are inserted and fixed by shrinkage fitting from both sides of the vessel 13, so that a delay circuit may be formed. Thereby, bending at the junction point of the units 13a and 13b, is suppressed design is facilitated, and the manufacturing process is simplified.

Abstract: PURPOSE: To eliminate nitrogen on a plasma nitride film or a plasma oxynitride film, and prevent reaction of chemical amplification type resist with nitrogen, by laminating the plasma nitride film or the plasma oxynitride film on a first film, spreading the chemical amplification type resist on an oxide film formed on the upper surface of the laminated film, and performing patterning. CONSTITUTION: A P-SiN film 2 is laminated on a first film 1 on a semiconductor substrate. The P-SiN film 2 is formed by using a parallel plate type plasma chemical vapor deposition equipment. Subsequently to the formation of the P-SiN film 2, the upper surface of the P-SiN film 2 is subjected to plasma treatment with oxidizing gas, e.g. nitrous oxide, by using the same equipment. In this case, nitrogen atoms or nitrogen molecules on the upper surface of the P-SiN film 2 or in the film are eliminated by oxygen atoms in the nitrous oxide, and instead, oxygen atoms are introduced, so that an oxide film 4 is formed. Chemical amplification type resist is spread on the oxide film 4 and patterned. Thereby a positive type chemical amplification type resist film 5 is formed.

Filed: 1990-01-08
Abstract: PURPOSE:To realize the stabilization of a laser and the reduction of noise by separating front outgoing light into two components of a low frequency component and a high frequency component, and changing the adding state of both the components according to a mode. CONSTITUTION:When the front outgoing light of the semiconductor 1 is transmitted through a beam splitter 3, a part of reflected light is detected by a monitor diode 12, and the low frequency component from DC to a servo band is amplified by a DC amplifier 13, and is fed back to the laser 1. The high frequency component is fed back as well through a coupling capacitor 14 and an C amplifier 15. Both the signals are added by an adder 18, but the adding state is changed by a switch 17 according to the mode signal 16 of reproducing, recording, and erasing. Namely, at the time of the reproducing and the erasing, both the low frequency and the high frequency components are applied in negative- feed back at the laser 1, and at the time of the recording, only the low frequency component is applied in negative-feed back at the laser 1. Thus, the stabilization of the laser and the reduction of the noise can be realized.

Title: Selective call receiver with display
Inventor: MIURA KUNIO
IPC: H04W88/02
Filed: 1987-01-08
Abstract: PURPOSE:To keep the secrecy of a message by deciding a code system in advance between a caller and a called party so as to display a reception message when a set code specific number is coincident with a code specifying signal specifying the code of the message. CONSTITUTION:A detection means M4 detects a code specifying signal specifying the code system of the received message signal and sends the result of detection to a deciding means M7. A setting means M5 sets the code specifying number specifying the code system decoded by its own receiver and sends it to the means M7. The means M7 decides whether or not the specifying signal of the means M4 is coincident with the specifying number of the means M5, and when it is decided to be coincident, the decoding means M8 decodes the message signal according to the code system corresponding to the code specification number coincident and stored in the code system storage means M6. Then a display control means M9 displays the message in response to the result of decoding. When the code specification signal included in the message signal corresponds to the code number of the code system to which decoding is not allowed by the receiver, even when the selection signal and its own number are coincident, the message is not displayed. Thus, when the code system is decided between the caller and the caller party, the secrecy is ensured.

Title: Internal trouble detector for electric equipment
Inventor: YAMAGISHI TAKESHI
IPC: G01R31/00
Filed: 1990-01-08
Abstract: PURPOSE:To judge an internal trouble in an electric equipment with a simplification of initial adjusting work, a smaller size and easier maintenance by detecting a quantity of light passing through an optical fiber which is adapted to cause a change in curvature with an extension or reduction of a bellows. CONSTITUTION:When an internal trouble occurs in an equipment S to be detected and causes a sharp rise in pressure inside a housing 1 by an energy generated by an arc A, an internal pressure of a bellows 4 rises sharply through a communicating tube 3. But the pressure in a closed container 2 communicating with a choke path 5 rises gently. As a result, with a pressure difference between the inside and outside of the bellows 4, it extends or reduces to increase a curvature of an optical fiber disposed in an extending or reducing area, which causes a decrease in quantity of light passing. Emission is introduced to the optical fiber 6 from a light emitting section 7 and received with a photo detecting section 8 after passing therethrough. A judging section 9 always compares an intensity of light emitted and that of light received and decides occurrence of an internal trouble when the resulting difference or ratio is below a specified threshold. This allows the using of the apparatus with a simple initial adjustment only requiring a change in the setting of the threshold regardless of variations in internal capacity of the equipment S.

Title: Memory circuit
Inventor: KOBAYASHI YASUO
IPC: G11C11/41
Filed: 1985-01-10
Abstract: PURPOSE:To heighten reading speed by making the length of the gate of a transistor for balancing bit line short. CONSTITUTION:The gate length L of a P channel type transistor Q103 for balancing bit line is made shorter than other P channel type transistors. When the gate length L is made shorter, subthreshold current I0 increases. In the case where the gate length L is made short until I0 (leak current of high resistance load) and IR become nearly the same, memory cell data are broken by subthreshold current I0 of the transistor Q103 when the word line Xj is high level. Accordingly, subthreshold current I0 is selected to 1/20 of leak current IR of high resistance load. Supposing that the gate length L in this case is LB, subthreshold current I0 of the P channel type transistor Q103 for balancing bit line is 1/20 of IR. Accordingly, absolute value of threshold value voltage of the transistor Q103 becomes smaller than other transistors, and balancing operation of bit line is made easy correspondingly.
