Title: Printer
Inventor: OOSHIMA HAJIME
IPC: G03G15/22
Filed: 1983-10-17
Abstract: PURPOSE:To perform fast continuous transfer and improve printing efficiency by selecting photosensitive bodies which are ready to transfer successively with the output of a signal generating means, and operating them in parallel at mutually different timing. CONSTITUTION:When a print command is outputted, a paper feed table 19 operates to start feeding paper 18, which is sent upward and downward selectively through a separation pawl 20. The paper 18 sent upward is reduced in speed along a roller 21 and a conveyance guide 22 to reach a gap between a roller 23 and a photosensitive body 27 to transfer a toner image written with a laser beam, and the paper is sent in the order of a guide 24 and a paper discharge roller 25 and stacked on a tray 26. Paper sent downward by the pawl 26 is handled similarly. The paper 18 is supplied continuously to an upper and a lower photosensitive body 27 by the pawl 20 and guides 22 with a speed reduction latch, so the throughput is doubled as compared with one photosensitive body 27.

Title: Primary low-pass filter
Inventor: MASUDA TOMOAKI
IPC: H03H11/12
Filed: 1987-08-03
Abstract: PURPOSE:To obtain a low-pass filter having a low cut-off frequency by connecting a capacity between the differential amplifying circuit output of an operational amplifier subjected to voltage follower connection and the output terminal of the operational amplifier. CONSTITUTION:When the mutual conductance of a transistor TR Ml and the channel conductance are denoted as gm1 and gds1 and TRs M1 and M2 have the same size and TRs M3 and M4 have the same size, gM1=gm2 and gm3=gm4 are true with respect to mutual conductance, and gds1=gds2 and gds3=gds4 are true with respect to channel conductance, and a gain A1 of the differential amplifier is expressed with a formula I. An output resistance Ro is expressed with a formula II. Consequently, a cut-off frequency f-3dB is equal to gm4/2piCc. The cut-off frequency is determined by the mutual conductance gm4 of the TR M4 and a value CC of a capacity 6. Since the mutual conductance gm of the TR is 10<-3>-10<-4>OMEGA and is proportional to (the drain current)1/2, the low cut-off frequency is attained with a small area.

IPC: B41F13/60
Filed: 1986-08-20
Abstract: PURPOSE:To secure the always same pulled-in state of a hooking needle by constituting a hooking needle operating cam into a groove or projecting stripe cam which is formed coaxial with the axis center of a bending trunk and constituting a switching device from a clutch and a clutch gear which perform connection and disconnection only with a same phase and installing an adjusting mechanism for the cam phase independently from the switching device. CONSTITUTION:A hooking needle operating cam 15 is formed into a groove or top cam which is arranged concentrically with a bending trunk, and a needle cam and a cam follower 14 are always in contact state, and the cam follower 14 can operate smoothly, In particular, when designing is performed with the lcous of the cam 15 with the adjusted timing in storing bending or direct bending, the pulled-in state of the needle call be made same in the both cases. Since the switching between the storing bending and direct bending is performed only in the case with the equal phase in the storing bending and direct bending, the phase of the hooking needle operating cam 15 can be allowed to coincide, and the phase of the cam 15 can be adjusted finely independently of the bending state.

Title: Changing-over room for vacuum switch
Inventor: KAARU SHIYUTEEKUMIYURAA
IPC: H01H33/66
Filed: 1989-07-27
Abstract: PURPOSE: To strengthen the durability of a casing for the switchover chamber of a vacuum switch by forming an elastically deforming section in a closure, joining a contact pin to the inner end thereof and connecting a plastically deforming section to the outer end thereof. CONSTITUTION: A closure is provided which has an elastic section of an extremely low spring constant associated with a plastically deforming section for reducing its contraction stresses caused by its manufacturing process. An especially effective structure of the closure is that a corrugated portion 24 made of an elastic material is joined to a contact pin 3 while a thin ring 25 made of a plastic metal is soldered at the end face of its outer leg 12a on an end face 13 of a ceramic tube 5. The ring 25 is airtightly joined at its flange 27 to the cover 24. The selection of the material and the shape of the thin ring 25 thus reduces contraction stresses of the closure, which strengthens the durability of the casing of a vacuum switch.

Title: Optical coupling device
Inventor: NAKAMICHI MASUMI
IPC: H01L31/12
Filed: 1989-07-25
Abstract: PURPOSE:To allow an optical coupling device to make high-speed responses to a high-speed optical signal by using a material having a small work function for a light receiving element and another material having a wavelength which is sufficient to exceed over the work function of the light receiving element for a light emitting element and housing the elements in a package in a united state. CONSTITUTION:When a light receiving element 11 is irradiated with modulated photons from a light emitting element 10, photo-electrons are emitted and an anode electrode 12 converges the photoelectrons. A material having a small work function is used for the element 11 and another material having a wavelength which is sufficient to exceed over the work function of the element 11 is used for the element 10, so that this optical coupling device can be sensitive to all photons having energy larger than the work function of the element 11. Therefore, the sensitivity at the short-wavelength side is improved and it becomes unnecessary for the light emitting element 11 to have a junction surface. As a result, the problem of junction capacitance is eliminated. The elements 10 and 11 and the electrode 12 are housed in a package 13 in a united state and the inside of the package 13 is set into a vacuum state or filled with a lean inert gas.

Filed: 1986-08-20
Abstract: PURPOSE:To control the progress of the oxidation of an electrode surface thereby to stabilize a laser output in a long term by providing an electric conductive oxide barrier layer on the surface of a cathode electrode. CONSTITUTION:When the surface of a cathode electrode is not oxidized, a high output laser can be stably obtained, but when the oxidation of the surface is advanced, an electron emitting function decreases. The cathode electrode 2' is provided with an electric conductive oxide barrier layer on the surface to relatively reduce the difference between oxygen concentration contained in laser gas and oxygen concentration existing on the surface of the electrode, and oxygen potentials approach. Thus, the progress of the oxidation is controlled. As a result, the life of the electrode is not only remarkably extended, but a laser output is stably obtained for a long period.
