Title: Method and apparatus for bonding inner leads
Inventor: SEKIYA JITSUO
IPC: H01L21/60
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To avoid breaking leads due to warp of a TAB(tape automated bonding) tape. SOLUTION: An inner lead bonding apparatus 10 for bonding pellets 1 to inner leads 8 on a TAB tape 3 comprises retainers 17, 21 having shapes matched to natural warp of the tape 3. The pellets 1 are hot compression welded to the inner leads 8 by a bonding tool 15 with the TAB tape 3 warped by the retainers 17, 21, and hence the bonded inner leads 8 keeping being warped are bridged between the pellets 1 and TAB tape 3. After the tape is released from the retaining force of the retainers, the warp of the tape is kept to result in that no stress caused by the warp of the tape acts on the inner leads and hence no inner lead is broken.

Inventor: KIKUCHI MAKOTO
IPC: G01R33/26
Filed: 1986-06-17
Abstract: PURPOSE:To reduce a spurious signal almost to the level of stationary sensitivity by an inexpensive means by loading an aperture formed of two nonmagnetic bodies with opening on the part of parallel light of two light beams. CONSTITUTION:A lens 2 collimates a light beam from a light source lamp 1 and a circuit polarizing plate 3 consists of two polarizing plates which differ in polarity from each other so that one polarizes light clockwise and the other polarizes the light counterclockwise. Further, an amplifier 6 amplifies an electric signal from a detector 5 while maintaining a necessary SN ratio and an adder 7 adds the signal from the amplifier 6. A signal processor 8 sends a prescribed signal to two RF coils 9 with the signal from the adder 7 and this system is locked on to the optimum point of magneto-optical resonance occurring to two absorption cells 4. The aperture 14 loaded between an absorption cell 4 and a photodetector 5 makes the magneto-optical resonance curve of the clockwise circular polarization system and the magneto-optical resonance curve of the counterclockwise circular polarization system completely symmetrically about an axis and the resonance point of their composition magneto-optical resonance curve is not shifted even by the maneuver of an aircraft, etc.

Title: Amplifier circuit for bs converter
Inventor: NISHIYAMA IKUMASA
IPC: H03F1/30
Filed: 1988-06-08
Abstract: PURPOSE:To attain small size and to reduce the cost with a few component number by using a bias stabilizing transistor(TR) suppressing the fluctuation of a drain current of a high frequency (RF) amplification FET so as to constitute an intermediate frequency (IF) amplifier circuit. CONSTITUTION:An IF signal given to an IF signal input terminal 13 is amplified by a TR Q2 and the result is outputted to an IF signal output terminal 14. A coil L1 exists between a collector of the TR Q2 (point a) and a gate of a FET Q1 and the coil L1 at the side of the FETQ1 is grounded via a capacitor C1. Thus, since the IF signal at the point (a) and the BS signal of the gate of the FET Q1 are insulated in terms of high frequency, the RF amplification by the FET Q1 and the IF amplification by the TR Q2 are implemented independently without any interference. That is, the bias stabilizing TR suppressing the fluctuation of the drain circuit of the RF amplifier FET is employed to constitute the IF amplifier circuit. Thus, number of components is reduced and the BS converter with small size and low cost is obtained.

Abstract: PURPOSE:To inexpensively and surely stabilize the resistance value of the electrical conductive brush of a brush roller by providing a current supply means making a prescribed constant current flow between the brush shaft of the rotating brush roller and a toner recovery means in a fixed time before an image forming device is used. CONSTITUTION:Before the brush roller 14 is actually used, it is driven to be rotated by a motor 18 controlled by a control board 28 and a prescribed position is occupied by a switch 29. When a power source 19 supplying current controlled to be constant is turned on, the constant current is supplied to the brush 17. Then, the current is made to flow to a toner recovery roller 15 through the brush 17 and the brush 17 becomes of a high resistance. When the resistance value thereof is stabilized, the switch 29 is changed over and the power source 19 is turned off. Then, the supply of the constant current to the brush 17 is stopped. Therefore, after the image forming device is actually started to be used, a prescribed bias voltage can be impressed on the rollers 15 and 14 by the power source 19.

Abstract: PURPOSE:To contrive to improve the efficiency of dehydration, while inhibiting the increase of sludge in volume, by prewashing digested night soil sludge with water to reduce the content of alkali components, in advance of pH-adjusting, freeze-thawing and dehydrating said sludge. CONSTITUTION:Digested sludge (a) formed by the aerobic or anaerobic treatment of night soil is washed with washing water (b) pref. in an amount of 2, more pref. 4, or more times the digested sludge at a water-washing site 11. Thereafter, the sludge washed with water is thickened by precipitation-separation at a precipitating site 12 and further thickened to a concentration of about 6-8% in terms of solid matter at a centrifugal thickening site 13. The pH of the conc. sludge is then adjusted using an acid such as sulfuric one or an acidic flocculant such as ferric chloride at a pH-adjusting site 1. Hereon, the increase of sludge in volume caused by the formation of CO2 is eliminated, since alkali components such as bicarbonate are previously removed by the washing with water. Thereafter, the sludge is carried through a freeze-thawing site 2 to a dehydrating site 3 and separated therein into an effluent (c) and dehydrated cake (d).

Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To dynamically generate a group in a shared virtual space. SOLUTION: When one of users comes into contact with a group control field, a participation declaring script is transmitted from that user terminal to center equipment (steps 41 and 42). The center equipment, where the participation declaring script is received, initializes the number of persons to be participated in the group and turns into the state of waiting for the declaration of the other user into the group (steps 43 and 44). Service start conditions in a group data table 13 at present are referred to (step 46) and when these conditions are satisfied, a service content script is transmitted to the user terminal (step 50) but when these conditions are not satisfied, the state of waiting for the declaration of the other user to be participated in the group is started.  In this standby state, the reception of the participation declaring script from the other user is waited or the count of group generation waiting time in the group data table 13 is updated (steps 47 and 48).
