Title: Reference hole boring method for multilayer circuit board and device thereof
Inventor: MURAYAMA TORU
IPC: H05K3/46
Filed: 1988-03-23
Abstract: PURPOSE:To enable a relative position to an inner-layer copper foil pattern to be maintained by an ordinary cutting tool by detecting conduction via a pattern between the tool and a contact electrode, or between contact electrodes each other, when the end of the cutting tool has reached the reference position pattern. CONSTITUTION:An end mill 5 rotates making a center of an axis O' and revolves making a center of an axis O, and a contact electrode 6 rotates making a center of the axis O. And, the end mill 5 is connected to a detector 14 via a slip ring 11, a contact 12, a slip ring 11', a contact 12', and a lead wire 13, and the contact electrode 6 is connected to it via the slip ring 15, a contact 16, and a lead wire 17. And, when the end mill 5 and the contact electrode 6 are turned and lowered, first, both are brought into contact with the outer layer copper foil 2a so as to be conducted however, after both have passed the outer layer copper foil, the conduction vanishes, and when both reach a reference position pattern 4, conduction is caused, and the detector 14 detects this to stop cutting operation. The end of the contact electrode 6 is made elastically movable slightly up and down from the plane with which the end of the end mill 5 is in contact, so that the contact at the time of the exposure of the reference position pattern is ensured, and while watching the reference working mark exposed subsequently, the whole can be penetrated, thus a reference working hole can be bored.
Patent JP-H08116678-A (JP)
Title: Bridge type invertor
Inventor: NAKAMURA MANTARO
IPC: H02M7/48
Filed: 1995-03-02
Abstract: PURPOSE: To reduce loss of not only a main switch bit of a partial resonance switch by generating pulses for controlling first and second main switches and pulses for controlling first to fourth auxiliary switches. CONSTITUTION: When a main switch TR1 is turned OFF and auxiliary switches S2, S4 are turned ON at a time t0, voltage of a capacitor C1 drops. When the voltage of the capacitor C1 reaches zero at a time t1, energy stored in a reactor L1 is discharged to produce a circulation current. Consequently, ZVS is achieved when a main switch TR2 is turned ON at t1. ZVS is achieved for a main switch TR1 at t0. Since an auxiliary switch S4 is a thyristor, it is turned OFF naturally when the current goes zero and since the current of the auxiliary switch S2 is zero at t0 and ZCV is achieved, switching loss is reduced for the main and auxiliary switches.

IPC: H01J61/56
Filed: 1983-04-21
Abstract: PURPOSE:To prevent an accident of burning a stabilizer while lighting a luminous tube when Xe is leaking into an outer tube by a method in case gas inside a luminous tube is leaking into the outer tube, a constant-opening heat-reacting switch, which operates to short a part of a starting device, is provided. CONSTITUTION:When the captioned discharge lamp is connected with an AC power source 23 through a stabilizer 22 for a mercury lamp of the single chalk type for a 200V class AC power source, a heat-reacting switch 9 is closed before lamp starting so that a coil filament 10 is conducted and heated so as to open the heat reacting switch 9 due to said heat. On the other hand, when Xe or the like, which is an enclosure inside a luminous tube, leaks out into an outer tube 1 due to leakage of a luminous tube 3, glow discharge is generated between a contact 18b of a constant-opening type bimetal switch 18, which is arranged separately and facingly, and a holding body extention 21a of the contact 9c of the heat-reacting switch 9 for pulse generation. The bimetal 18a of the constant- opening type bimetal switch 18 is curved and deformed due to heat thereby generated so that said contact 18b contacts the holding body extension 21a while preventing the stabilyser 22 from burning without lighting the luminous tube 3.

Title: Control device for shock absorber
Inventor: SUZUKI YUTAKA
IPC: F16F9/50
Filed: 1990-03-19
Abstract: PURPOSE:To prevent changeover shock in a shock absorber control device for changing over damping force characteristic according to a road surface condition, by quickening the changeover speed of the damping force characteristic compared with the speed at the rate of change in a standard range, when the rate of change of the damping force is over the prescribed standard range. CONSTITUTION:When a road surface condition detecting means M2 detects unevenness of a road surface condition, a damping force characteristic changeover means M3 changes over the damping force characteristic of a shock absorber M1 to the small side. Meanwhile, the rate of change of damping force detecting means M4 detects the rate of change of damping force, and sends it to a changeover speed control means M5. The changeover speed control means M5 sets the changeover speed based on the rate of change of damping force. In this case, when the rate of change of the damping force exceeds the standard range, the changeover speed is set more quickly compared with the speed at rate of change in the standard range. By this constitution, changeover shock can be prevented.

Filed: 1983-04-20
Abstract: PURPOSE:To prevent a developer from attaching to nonimage parts by photosensitiveally charging the nonimage parts of an image bearing body having the nonimage parts not participating in image formation, to the same polarity as that of the developer. CONSTITUTION:A side seal 9 is attached to the border of the opening of a cleaner 7 on the side of a photosensitive body 1 to prevent a developer scraped with the cleaner 7 from falling into an apparatus. This side seal comes into friction contact with the nonimage parts D of the body 1 to charge the insulating layer of the surface of the body 1. A developing sleeve 12 of a3 width does not contact with the nonimage parts (b), but in reversal development, the developer on the end of the sleeve 12, a positive toner in that case, is pulled little by little till attaching an image part and staining occurs. Therefore, high positive voltage is applied to a predestaticizer 10 having a destaticizing width C to positively charge the nonimage parts (b). As a result, the developer does not attach to the nonimage parts, and various kinds of trouble due to the attachment staining of the side seal 9 are prevented.

Abstract: PROBLEM TO BE SOLVED: To provide a steering shaft whereby a large twist load input from a wheel can be absorbed, also even after absorbing twist force, the wheel can be steered by operating a steering wheel, and this twist force can be permanently absorbed over several times. SOLUTION: In a steering shaft 10, an end part of a core wire 12 is held to an adapter 18 of a holding part 16, and by a belleville spring 40, a pressed slider 38 is brought into contact. In a periphery of the core wire 12, a flexible member 28, right/left windings 22B, 22A are provided. When large twist force acts in the steering shaft 10, the core wire 12 tends to move to a side of the slider 38, by elastically deforming the belleville spring 40, moving force of this slider 38 is absorbed. Further, by resetting to the former condition, even after absorbing a load, a wheel can be steered.
