Title: Gas laser device
Inventor: NOZUE YASUHIRO
IPC: H01S3/034
Filed: 1986-06-30
Abstract: PURPOSE:To prevent impurities from sticking to a window and to increase laser output by a method wherein a means is provided at an opening in a chamber for the prevention of adhesion to the window of impurities present in the chamber. CONSTITUTION:A unit of this design is provided with an opening 3c whereat laser is emitted upon charging of a laser material, a window 5 that may close the opening 3c leading to a gas laser unit chamber, and a impurities adhesion preventing means 20 installed on the opening 3c for the purpose of preventing impurities from sticking to the window 5. In an impurities adhesion preventing means 20 of this design, for example, a cylinder 21, with its center axis coinciding with the laser beam optical axis L, is installed on the opening 3c that is positioned within a chamber flange 3b, and a plurality of wall panels 23 are arranged on the inner wall 22 of the cylinder 21. With the unit being constructed as such, impurities travelling afloat from the direction of the chamber inner wall are allowed to adhere to the outer circumference of the cylinder 21 while impurities entering the cylinder 21 after traveling afloat toward the optical axis L are, because their velocity component along the optical axis L is smaller, soon to loose velocity and land on the wall panels 23 without reaching the window 5.

Title: Bender device of electronic musical instrument
Inventor: SUZUKI AKIHIRO
IPC: G10H1/32
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To reduce the height of a bender device itself and to improve the degree of freedom in a mounting place without impairing the operability of this device by changing the sliding of an operating element to the turning of a turning shaft and changing the resistance value of a variable resistor in accordance with the turning angle of the turning shaft. SOLUTION: This bender device has the variable resistor 50 of a turning type and the operating element 51 freely slidably disposed in a guide groove 10a. The resistance value of the variable resistor 50 is changed by turning the turning shaft 50a. The sliding of the operating element 51 is converted to the turning of the turning shaft 50a by intermeshing of the gear part 51a of the operating element 51 and the gear 54 of the turning shaft 50a at the time of changing the pitches of the produced sounds of the electronic musical instrument by the sliding of the operating element 51. The free setting of the sliding width of the operating element 51 to the sliding width easily operative for a player is, therefore, made possible by setting the gear ratio of the gear part 51a and the gear 54.  The need for a large member which partly projects to the surface of the electronic musical instrument and turns is eliminated and the degree of freedom in the mounting place is increased.

IPC: H04N5/335
Filed: 1988-06-21
Abstract: PURPOSE:To suppress a fluorescent lamp flicker by integrating a smear signal from a solid-state image pick up device, reading it and utilizing it as a reference charge for a control signal. CONSTITUTION:At time t1 of a first field, impressed pulse phiV2 and phiV4 of electrodes G2 and G4 of the solid-state image pick up device repeat an H level and an L level, impressed pulses phiV1 and phiV3 of electrodes G1 and G3 repeat an M level and the L level, respectively, and a smear charge is transferred. For an impressed pulse phiH of an electrode G5, the smear charge is added to a horizontal transferring part 5 at the H level. At time t2, the pulse phiH repeats the H level and L level, the added smear charge is transferred, and it is outputted to an output part 6. At time t3, the pulses phiV1 and phiV3 are both made into the H level, and a signal charge is read. In the period of time t4, the signal charge is successively outputted from the output part 6. In a second field, the same action is executed. Thus, a reference signal having a correlation with information, in which the signal charge is integrated in one field, can be obtained with high accuracy.

Title: Manufacture of display unit
Inventor: SHINOHARA MASATO
IPC: H05K3/12
Filed: 1977-12-21
Abstract: PURPOSE: To give variety to display and to reduce cost by using an optical filter for optical display or an offset printing method for designing.  
     CONSTITUTION: The negative of an aluminium plate is coated with photosensitive resin and a photographic film in a desired shape is copied on a smaller scale and made in contact with the negative, thereby forming a pringing negative through exposure and development. Since the negative obtained in this way has resolution of approximate 5 to 10μ, high precision can be obtained as compared with screen printing and electrostatic printing. In addition, the need of an etching process as a negative is nearly eliminated, so that it will be very different in precision with both intaglio printing and anastatic printing. Further, an offset negative is extremely cheap. A negative with mesh dots of approximate 5 to 10μ can therefore be formed with high precision and low cost by offset printing; decreasing this density of mesh dots makes the negative halftone close to transparent and increasing it makes it semitransparent. In this way, the mesh density is varied to give variety to display.

Title: Writing error processing method for magnetic tape device
Inventor: ISHIGURO MASAYUKI
IPC: G11B20/18
Filed: 1985-07-12
Abstract: PURPOSE:To prevent the further retry by comparing an erasion block length with a prescribed length and producing a tape error when the erasion block length is larger than the prescribed length. CONSTITUTION:An MPU 30 analyzes the informed error contents and an error information producing routine is set if an error of a magnetic tape device is detected. Then the working of the tape device is stopped and this abnormal end is reported to a host controller. If a writing error is detected, the contents of a retry count area RC of a RAM 31b are checked to decide whether the retry frequency exceeds the prescribed limited level or not. Then the set recording density is checked if no retry-out state is detected. Then it is decided whether the contents of an IBG length area IC exceed the limit length 6m or not when the recording density is equal to 1,600bpi. While it is decided whether the contents of the area IC exceed the limit length 3.6m or not when the recording density is equal to 6,250bpi. Then an error information producing routine is set if the contents of the area IC exceed the limit length. Thus the working of the tape device is stopped and the abnormal end is reported.
