Title: Ink feed device
Inventor: ITOU YOSHIO
IPC: B41J2/175
Filed: 1981-10-07
Abstract: PURPOSE:To improve an ink jet system recording head so that it is capable of performing stable ink jetting by such an arrangement wherein the ink tank of the head is divided into more than 2 chambers and one of chambers near the head is completely filled up with ink. CONSTITUTION:Since ink jet recording is carried out by the repetition of reciprocating movement of a scanning table 11, ink 12 inside a subtane 13 is largely disturbed by the repetition of acceleration and deceleration of the table 11 and it generates innumerable air bubbles, large and small. Due to this, a partition plate 18 having a narrow passage 30 is almost horizontally arranged in the subtank 13 and ink is caused to flow into the upper chamber 13a of the subtank 13 from a main tank 26. The upper chamber 13a generates air bubbles since ink is disturbed by the reciprocating movement, but the lower chamber 13b interconnected with the narrow passage 30 is filled up with ink, therefore it has no space wherein disturbance is generated and ink inside the chamber remains as gentle flowing condition and it does not generate air bubbles at all. Also, ink inside the upper chamber 13a does not generate downward motion passing through the narrow passage 30, therefore generated air bubbles do not reach the lower chamber 13b, consequently the head performs stable ink jetting.

Title: Manufacture of semiconductor device
Inventor: SHIMADA TOSHIYASU
IPC: H01L23/544
Filed: 1986-07-07
Abstract: PURPOSE:To obtain a distinct imprinting character having excellent visibility by conducting resin seal by using an epoxy resin containing fillers colored to yellow or brown and performing imprinting by employing a laser to a resin surface. CONSTITUTION:The sealing work of a semiconductor device is executed by using silica powder colored to yellow or brown as fillers and by employing an epoxy resin for sealing including carbon powder for coloring the epoxy resin. The appearance of the semiconductor device acquired in this manner does not differ from normal devices at all because the surface is covered with carbon powder and the epoxy resin. The semiconductor device is irradiated with an imprinting character pattern by using a YAG laser. Consequently, carbon powder and the epoxy resin on the surface are removed, and colored silica powder appears in response to the character pattern. The epoxy resin receiving the YAG laser is deteriorated by the heat of the laser, and discolored to yellow or brown, but a color shade in the character pattern is also reduced because silica powder as fillers is also colored to yellow or brown, thus acquiring a distinct imprinting character having excellent recognizability.

Title: Synchromizing clock generating device
Inventor: ISHIZAWA HIROAKI
IPC: G06F1/04
Filed: 1986-07-08
Abstract: PURPOSE:To generate a clock with high synchronizing accuracy and to facilitate polyphase clock and the revision of its output mode by generating four kinds of clocks with the same frequency but different phase so as to generate a biphase clock synchronously with an external phase reference signal. CONSTITUTION:The clock generating circuit 20 generates four kinds of clocks F1-F4 having the same frequency but different phase. A FF 23 latches the clocks F1-F4 in the application timing of an external phase reference signal PS simultaneously. A conversion table LUT 24 receives a latched data as an address and converts the data into the selection information to select any two- kind of clocks having the phase closest to that of the signal PS among the clocks F1-F4. A FF 25 latches the conversion output data of the LUT 24 simultaneously based on a signal DPS being the result of delay given to the signal PS by a required value by a delay line 26. One kind of clocks designated by a selection data D1 or D2 outputted from the FF 25 is selected at any time among the clocks F1-F4 by selectors 27, 28. The selecting mode is set logically so as to be made coincident with the clock designation mode by the selection information of the LUT 24.

Filed: 1982-09-13
Abstract: PURPOSE:To perform transition to a focus detectable area by providing a discriminating means which discriminates the position of a lens system stopped in such a state that focus detection is impossible and controls the lens system to a focusing position. CONSTITUTION:When the lens is in a focus undetectable area on a close-distance focusing side, the output A of a comparing circuit 15 goes up to a high level, the output of an OR gate 18 also goes up, and a switch SW1 turns on to move the lens to a long-distance focusing side. When the lens is in a focus undetectable area on the long-distance focusing side, the output A of the comparing circuit 15 goes up to the high level, the output of the OR gate 18 also goes up, and a switch SW2 turns on to move the lens to the short-distance focusing side. Thus, the lens is moved to the focus detectable area in either case.

Title: Laser light radiation method
Inventor: KAWASUMI HIROMICHI
IPC: H01S3/00
Filed: 1978-12-25
Abstract: PURPOSE:To achieve the improvement in working accuracy such as heat treatment and coating by letting the laser light of a circular pattern enter a pyramidal prism and converting the same to a pattern having a square contour thereby making the temperarure distribution of the radiated portion nearly even. CONSTITUTION:The energy distribution of the laser light L of the circular pattern P1 outputted from a laser oscillator 1 is high at the center and becomes lower toward the periphey. When the pattern P1 enters a pyramidal prism 3, it is divided and inverted to four patterns P2 assuming a fan shape of 90 deg. owing to its optical characteristics. These are then focused by a convex lens 4 to assume a contour of a square shape which radiates the working surface 5a. The energy distribution of this time is highest at the angle parts of the square contour and becomes lower toward the center but, at the working surface 5a radiated, the transfer of heat takes place rapidly from the periphery toward the center and becomes nearly even. In this way, working such as heat treatment and coating may be accomplished with high accuracy.
