Patent JP-H0371855-A (JP)
Title: Dot printing head
Inventor: SAKAIDA ATSUO
IPC: B41J2/295
Filed: 1989-08-11
Abstract: PURPOSE:To prevent or muffle noise generated between the contact surfaces of a frame and a support member of a printing unit by allowing a damping member consisting of an antioscillation material to be present between the frame and the support member. CONSTITUTION:A stepped part 86 surrounding an introduction hole is formed on the contact surfaces of a support member 50 and the main frame part 2 of a frame 80, and a ring-shaped damping member 87 consisting of an antioscillation material such as rubber or synthetic resin is insetted on the stepped part 86. In addition, the damping member 87 is held in a squashed condition between the support member 50 and the frame 80. Consequently, a motion conversion mechanism of the printing unit is activated and the damping member 87 absorbs and restrains the oscillation of the frame, if such occurs. Thus the noise generated between the contact surfaces of the frame 80 and the support member 50 is prevented or reduced.

Title: Fet nand logic circuit
Inventor: SUYAMA KATSUHIKO
IPC: H03K19/0952
Filed: 1988-08-24
Abstract: PURPOSE:To surely clamp the high level value of an input voltage with a special voltage by providing a first input terminal to connect the gate of a high potential side driving FET and the gate of a low potential side pulldown FET and a second input terminal to connect the gate of a low potential side driving FET and the gate of a high potential side pulldown FET. CONSTITUTION:When an input voltage A is a high level and B is a low level or an input voltage A is a low level and B is a high level, concerning respectively serially connected driving FET Q1 and Q2 and pulldown FET Q5 and Q4, either of them becomes an off condition. Consequently, the gate and the source potential of a load FET Q3 and a source follower FET Q6 are advanced and an output X becomes a high level. At this time, based on a high level input A or B, a flow current flows from either of the gate of a low potential side driving FET Q2 or the gate of a low potential side pulldown FET Q4 to a ground side. Thus, the high level input can be clamped to a forward direction ON voltage VF between gate sources.

Title: Packaging method for semiconductor element
Inventor: WARFIELD TIMOTHY J
IPC: H01L23/02
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To provide a packaging method in which the strength of a cap wafer is sustained, even if the density of dies on an element wafer increases bonding pads can be accessed easily and stress onto the element is minimized. SOLUTION: A semiconductor element on an element wafer 30 is packaged using a cap wafer 10. Cavities 27 are formed by a performing partial etching a plurality of times continuously from the surface of the cap wafer 10 to the inside thereof. The partial etching pattern of the cavity 27 depends on the pattern of dies 32 on the element wafer 30. The cap wafer 10 is then aligned with the element wafer 30 and bonded thereto, using glass frit as an adhesive. Thereafter, the thickness of the cap wafer 10 is decreased from the rear side 127, until the rear surface thereof reaches the cavity 27 formed by partial etching. Finally, the element wafer 30 is diced to produce individual dies 32.

Title: Optical information processor
Inventor: TANIGUCHI HIDEO
IPC: B41J2/45
Filed: 1986-09-03
Abstract: PURPOSE:To prevent an error generated at the time of forming information onto a photosensitive body without raising the cost of a light emitting body, and without complicating an optical information processor, by setting the transmissivity of each transmission part in accordance with an optical output of the corresponding light emitting part. CONSTITUTION:In case when a variance of an optical output (p) of a light emitting part 1a is as shown by a figure (b), and there is no light quantity adjusting means 2, as for an exposure quantity (e) on a photosensitive body 3, a variance is generated as shown by a broken line in a figure (d). Therefore, when a light quantity adjusting means 2 which has set the transmissivity tauof a transmission part 2a in accordance with the optical output (p) of the corresponding light emitting part 1a, as shown in a figure (c) is interposed, the exposure quantity (e) on the photosensitive body 3 is equalized as shown by a full line in the figure (d). In this way, an error at the time of forming the information onto the photosensitive body 3 is prevented, it becomes unnecessary to select and use a light emitting body for scarcely generating a variance of an optical output, and the cost is reduced.

CONSTITUTION: A folk lever 25 and an eccentric pin 20 are rotated by a hydraulic cylinder 26 after a plate end section 5 is fixed to both sides of a fixing lever 9 by the rotation of an eccentric fixing pin 34 via a clamp stay 32. This causes a fixing belt plate 15 to be moved to the elongated direction and the plate end section 5, when moved outside, is clamped between the clamp stay 32 and the fixed surface 36 and thus, extended. The movement of the fixing belt plate 15 to the center of a cylinder enables the compression of the printing plate end section. To what extent the rear plate end section 5 can be extended or compressed depends on the required correction of the printed surface. The clamping of the plate end section centers by a clamp stay 10, also enables the adjustment of the fixing belt plate 15 and the rear printing plate end section 5.
