Title: Ozone sensor
Inventor: TACHIBANA KOICHI
IPC: G01N27/04
Filed: 1991-03-01
Abstract: PURPOSE:To correctly sense ozone and also improve thermal stability by suppressing influence of reducing gas and oxidizing gas which interfere with sensing of ozone. CONSTITUTION:A coating layer 3 mainly containing at least one of oxides selected from compounds of MnO2, FeO3, Co3O4 and NiO and MgO is formed to completely cover a gas sensor 2. Since a reducing gas is oxidized and inactivated by oxidation catalyst action of oxide such as MnO2, influence of the reductive gas to the sensor 2 is reduced. Oxidizing gas reacts with MgO to generate salt, which prevents the oxidizing gas from directly functioning to the sensor 2. Further MgO prevents the coating layer 3 and the sensor 2 from being sintered to suppress change with time of sensor characteristics.

Title: Mass spectrographic method
Inventor: TAKEDA TSUNEZO
IPC: G01N27/62
Filed: 1986-02-20
Abstract: PURPOSE:To prevent a detector from deteriorating in sensitivity by inhibiting ions of an unnecessary gas component from reaching the detector. CONSTITUTION:A mass scan is made repeatedly and continuously and a mass spectrum is measured to perform mass spectrometry, but the object of this mass spectrometry is an extremely small amount of impurity gas and main component gas is unnecessary for the mass spectrometry. For the purpose, data on unnecessary main component gas other than the object gas is inputted previously to a control circuit 16 and when unnecessary gas is admitted to an ion source 4, a control signal is supplied from the circuit 16 to an aperture power source 14 for a mass scan time corresponding to the mass range of the unnecessary gas. Then a voltage for stopping ion passage is applied to at least either of an ion projection part 8 and an ion incidence part 10 to prevent ions of unnecessary gas components from reaching the detector 6, which is therefore prevented from deteriorating in sensitivity.

Title: Audio muting circuit
Inventor: NOJIMA SATORU
IPC: H03F1/00
Filed: 1992-02-24
Abstract: PURPOSE:To slow downs the transition of an audio signal from a level in the mute state into a steady-state operating level by acting the muting circuit such that the audio signal transits to the steady-state operating level with a gradual increase after the audio signal is muted for a prescribed time. CONSTITUTION:When a prescribed time (e.g. 300ms) elapses after an audio signal (c) is muted, a level of a control pulse (a) reaches 0V. Thus, a transistor(TR) 1 of a pulse generating circuit 3 is turned off and an input level (d) of a differential amplifier 6 rises gradually from 0V. Then the input level reaches a state in crossing with other input (e) of the amplifier 6. A level of an output pulse (b) is 0V for the crossing period, and then the audio signal is not muted, and a level of the output pulse (b) is nearly +V1 for the period not in crossing and the audio signal is muted. That is, the audio signal is muted or not muted at a period equivalent to 40kHz and the duty factor of ON is gradually increased. The ON/OFF signal is filtered by an LPF 2, a mean value is an audio output (c) and it is gradually increased with the ON duty factor, the OFF period reaches 0 and the state is restored to the steady-state operation.

Filed: 1987-02-19
Abstract: PURPOSE:To generate a desired beat frequency by polarizing a 1st laser light of laser light which is emitted by a common laser light source and split into two by an acoustooptic modulating element and imposing frequency modulation, converting it to an optical path parallel to the optical axis through an optical path converting element, and mixing the light with the other laser light by an optical mixing means to cause interference.

Title: Impact dot head
Inventor: TAKEUCHI TAKASHI
IPC: B41J9/42
Filed: 1989-02-16
Abstract: PURPOSE:To reduce abrasion of a plunger without sacrificing efficiency of a magnetic circuit by providing a stopper which restrains a lever from being displaced so that the surface at the core side of said plunger is out of contact with the other members when printing is not conducted. CONSTITUTION:When printing is not conducted, that is, a printing apparatus is in a waiting state, a plunger 3 receives the attracting force to a core 5 by a magnetic flux generated by a permanent magnet 4, and accordingly the plunger 3 is attracted to the core 5 while it biases a spring 7. Since a lever 6 is hindered by a stopper 9 from advancing before the plunger 3 comes into contact with the core 5 through a spacer 1, an end face 3a of the plunger is maintained out of contact with the other members. On the other hand, when printing is conducted, since an electromagnetic coil 2 is made conductive, the magnetic flux generated by the permanent magnet 4 is erased, thereby releasing the plunger 3 from being attracted to the core 5. At the same time, a wire 8 fixed to an end of the lever 6 is projected by the force of the spring 7.

Abstract: PURPOSE:To smoothly change charge data by inputting charge data and switching time required for charging, and automatically executing switching to the charge data at the switching time. CONSTITUTION:First of all, when a maintenance person inputs switching date and new charge data from an input device 1 by prescribed operation processes, a charge controller 100 writes the input data in a charge data switching table. The device 100 discriminates whether switching data are present or absent and when no data exist, the processing is finished.

When the switching time does not pass, the processing is finished and when it passes, it is discriminated while referring to a trunk state table whether there is any central office trunk under using or not. When there is such a central office trunk, the processing is finished and when such a central office trunk is not existent, the contents in the new charge data area of the switching table are transferred to an old charge data area. Next, dummy bits are set to a switching date area, switching time area and new charge data area, and the contents are cleared.
