Title: Laser recording method
Inventor: FUNATO HIROYOSHI
IPC: G03G13/01
Filed: 1984-12-25
Abstract: PURPOSE:To deflect plural laser beams simultaneously by the same holodisc by providing the holodisc with one or more tracks consisting of circular arrays of plural hologram gratings or hologram lenses. CONSTITUTION:A holodisc 12 is formed to a disc shape, and two tracks of hologram gratings are formed on one surface of its transparent substrate. Each laser beam is diffracted by hologram gratings on the holodisc 12 and reaches a photosensitive body 30A or the like through an optical path. When the holodisc 12 is rotated by a motor 14 in this state, individual diffracted laser beams are deflected synchronously, and the spot of each beam on the photosensitive body scans optically the photosensitive body. Thus, since laser beams which scan plural photosensitive bodies are deflected simultaneously by the single holodisc, it is unnecessary to provide a laser beam scanner for each photosensitive body, and the recorder is simplified.

IPC: B25J9/16
Filed: 1984-12-29
Abstract: PURPOSE:To minimize a delay time and to approach easily a robot locus to a desired route by deciding the timing when an operation is shifted to an acceleration control operated by a speed command to a next command position in accordance with the number of built-in pulses after the deceleration of a feed speed. CONSTITUTION:An acceleration/deceleration circuit 1 starts its deceleration when a residual moving amount from an interpolating circuit 2 is fed back and a deceleration speed corresponding to the feed speed is equal to said amount. Whenever an output pulse Fj is generated from the circuit 1, the circuit 2 executes the pulse distribution and arithmetic based on moving amount data to generate distribution pulses Xp and Yp, drives servo motors 41 and 42 through servo circuits 31 and 32, detects a command pulse remaining amount at deceleration, specifies the start timing of the distribution pulse arithmetic in a next moving route with the aid of the detected remaining amount and a parameter (a) for specifying a built-in amount, and adds a command pulse for adding the feed speed in accordance with the command speed F and the command position to that at deceleration.

Title: Manufacture of lead frame material
Inventor: MUKAI KATSUHIKO
IPC: H01L21/48
Filed: 1984-12-24
Abstract: PURPOSE:To contrive to simplify the manufacturing process and to reduce the residual distortion inside the material by a method wherein an alloy ingot is hot-rolled and cold-rolled, then slit-cut into cold rolled materials before finish rolling, annealed for softening, and finish-rolled in cold to the thickness of the titled material. CONSTITUTION:As the alloy for this material, Ni-Fe alloy, Ni-Co-Fe alloy, and Cu series alloy can be used. The Ni-Fe alloy has the minimum coefficient of thermal expansion in the case of Ni 36%, and so as Ni content of 30-35% is used. For example, a 42% Ni-Fe alloy ingot is hot-forged and then hot- and cold-rolled into an intermediate rolled band plate, and this band plate is slit-cut into the plate width almost equal to the width dimension of the lead frame material. Then, this slit plate is continuously annealed and then cold finish-rolled into a lead frame material without distortion. Thus, the lead frame material of uniform cross-sectional dimension can be produced with less internal distortion.

By this pivoting operation, a paper bail 3 is separated from the printing paper 1 pressed down thereby and at the same time, a cap 13 moves to the printing head 9 side to cover the nozzle part of the printing head 9. At that time, the cap 13 pivots freely around a supporting axis 11 and is energized onto the printing head 9 side with a spring. Therefore, a nozzle part 12 is certainly covered by the cap 13. Then, the nozzle part 12 is prevented from drying and clogging.

Title: Quartz crucible for lifting silicon single crystal
Inventor: TSUJI YOSHIYUKI
IPC: C30B15/10
Filed: 1989-10-27
Abstract: PURPOSE:To provide a quartz crucible substantially not affected by impurities by adding the group V element for forming an n type semiconductor and the group III element for forming a p type semiconductor in a specific ratio. CONSTITUTION:The quartz crucible contains the group V element for forming an n type semiconductor and the group III element for forming a p type semiconductor in a ratio of 1:0.5-5. The group III element such as B and the group V element such as P or As are dopants for forming p type and n type semiconductors, respectively, and have a p, n compensation relation in a silicon single crystal. Since it is expected that the coexistence of the elements cancels the effect of the other element each other, the group III and V elements are added in such amounts as cancelling the effects each other, thereby providing a quartz crucible capable of neglecting the effects of the elements. When the above-mentioned ratio is 1:<0.5, the compensation effect is insufficient, while the ratio of 1:>5 is undesirable because the silicon single crystal causes p-n reversion.

Abstract: PURPOSE:To improve stabilization of sampling time, measuring accuracy and S/N ratio by performing a processing with a first low pass filter for a signal for azimouth adjustment and a processing with a second low pass filter for a signal for head position adjustment. CONSTITUTION:A switching pulse generation circuit 6 generates a pulse based on a signal indicating an input timing of an index burst signal to change over a changeover switch 2 so that a regeneration signal is sent to the side of a first low pass filter 10 when the time at which a burst signal (AB) for azimouth adjustment begins to be regenerated is reached. The circuit 6 generates a pulse so that a signal is sent to the side of a second low pass filter 20 when the time at which an analog waveform signals (C11, C12) for head position adjustment begins to be generated. Thus, when the signal AB is supplied to an input terminal 1, it is sent to the filter 10 excellent in transition characteristic and when the signals C11 and C12 are supplied, it is sent to the filter 20 excellent in attenuation characteristic.

Title: Destaticizing method for image carrier
Inventor: NAKAYAMA SHIGERU
IPC: G03G21/06
Filed: 1986-11-21
Abstract: PURPOSE:To eliminate an unnecessary development and a local fatigue from an image carrier after printing and to obtain a sharp and excellent image by operating a destaticizing means together with the start of the rotation of the image carrier and making the destaticizing means inactive as soon as the image carrier actually stops. CONSTITUTION:When a motor 5 is turned on, a CPU unit 10 outputs a signal shown by a figure (a) from a rotary encoder 6, and simultaneously causes a driving circuit 11 to generate an output and the destaticizing means 12 to operate. After printing has ended to turn off the motor 5, an output shown by a figure (b) is outputted from the rotary encoder 6. As long as the motor 5 rotates, the output is provided. Hence the CPU unit 10 detects that the output from the rotary encoder 6 is not found in 0.2sec through calculation, stops the output from the driving circuit 11, and makes the destaticizing means 12 inactive. Thus, since the destaticizing means 12 is turned off while the image carrier 1 is rotating, fogging and back soil, which are caused by turning off the destaticizing means 12, and the local fatigue which stems from the exposure by the destaticizing means 12 when the image carrier stops its rotation are eliminated.

IPC: C21B5/00
Filed: 1984-12-29
Abstract: PURPOSE:To prevent the rearrangement of fine-grain coke and to utilize effectively said coke by segmenting preliminarily the coke charged into a blast furnace in a laminar state to coarse grains and fine grains and charging the fine-grain coke in an intermediate batch except the first and final batches into each layer. CONSTITUTION:The above-mentioned coke 2 is preliminarily segmented to the coarse grains and fine grains in a method for charging raw material into the blast furnace in which the iron ore 1 and the coke 2 are charged in the layer state into the furnace while adjusting the distribution thereof by a large bell 4 and a movable armor 3 in the furnace top.

The direct contact of the iron ore 1 and the coke 22 is thus prevented and the rearrangement of the coke 22 is prevented. The controllability of the layer thickness ratio between the ore 1 and the coke 2 is thereby improved and the effective utilization of the coke 22 is made pos sible.
