Title: Vibration motor having no output shaft
Inventor: YAMAGUCHI TADAO
IPC: H04W84/02
Filed: 1990-10-31
Abstract: PURPOSE:To obviate the necessity of high accuracy for each component by securing a shaft to housing and mounting a rotor rotatably on the shaft through a bearing. CONSTITUTION:A stainless steel shaft 2 is press-fitted through a shaft holder Aa in the center of a casing 1 constituting a part of housing and a rotor 5 is mounted on the shaft 2 through an oil retaining bearing 3 and a holder 4 subjected to oil barrier treatment. Since the shaft is fixed and the bearing is made rotatable, coaxial problem of upper and lower bearings can be eliminated perfectly. A single oil retaining bearing causes cost reduction while a ball bearing causes reduction of side pressure loss and current consumption. When a fixed shaft is employed in a battery type oscillation motor, means for isolating between the casing and a bracket 9 can be neglected for the shaft part and thereby the structure is simplified.

Filed: 1985-12-25
Abstract: PURPOSE:To reduce the cost of a device by providing a chopper element in an electric passage from a DC power source to a solenoid for braking and eliminating the need for using two types of high and low power sources. CONSTITUTION:When a brake-ON command is externally given, a chopper element is kept an ON condition during a time T1.

After that, the chopper element repeats intermittent operations at an OFF time T2 and an ON time T3. Accordingly, two types of high and low power sources are not necessary, leading to reduction in the cost of a device.

Title: Plate for screen printing
Inventor: MIURA YUTAKA
IPC: H05K3/34
Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To prevent the screen mesh part from deforming due to a contraction/ stretch extending to a long period of time by a method wherein respective contact parts where respective wires being woven into a mesh-form in a printing pattern forming area, cross, are fastened to each other. SOLUTION: Respective wires 6a, 6b which are woven into a mesh-form in a printing pattern forming area 3, are formed by a molding process wherein e.g. an appropriate pressure is applied from the vertical direction, and the wires 6a, 6b are pressed so that the contact parts where the wire 6a and the wire 6b cross, may bite in to each other. A supporting area 4 which supports the periphery of the printing pattern forming area, is formed in such a manner that the wires 6a, 6b simply cross with each other and are woven into a mesh- form. In a plate for printing which is constituted in such a manner, even when a printing pressure is applied to the screen mesh part 2 at the time of screen printing, the contraction/stretch due to the pressure is absorbed by the supporting area 4, and a deformation is prevented from generating on the printing pattern.  Therefore, the deformation of an electronic circuit pattern which is printtransferred on a substrate is completely eliminated.

Abstract: PURPOSE:To shorten the operation time of a host computer by starting a program performing long connection recording and providing a RAM capable of storing the data related to long connection drawing to a recording apparatus and transmitting all of data from the host computer successively and continuously. CONSTITUTION:When a long connection drawing mode is set and a drawing program is started, drawing data are continuously sent from a host computer to be successively written in the RAM of a plotter. In the case of the data received in the No.1 frame, drawing is executed. When the data are not received in the No.1 frame, recording is carried out by the quantity corresponding to the recording frame concerned of the drawing data and the residual drawing data are stored until final frame recording and only the part corresponding to the recording frame concerned is recorded in each of the corresponding recording frames. Since a data transmitting time is shorter than the drawing time of one frame, the operation time of the host computer for the transmission of data can be shortened.

Title: Shift controlling method for automatic transmission
Inventor: ASADA TOSHIYUKI
IPC: F16H61/04
Filed: 1989-11-13
Abstract: PURPOSE:To lighten a shift shock by making it so as to perform a desired shift gear speed by way of such a shift gear speed which is less in the number of friction engaging means changing an engagement-release state simultaneously in substance, among interposing shift gear speeds, and cumulative variation revolution of each rotating member in a gear train. CONSTITUTION:Among shift gear speeds interposing between the existing shift gear speed and a desired shift gear speed to be set by doing a speed change, an intermediate speed, which is less in cumulative variation revolution of each rotating member and the number of friction engaging means to change an engagement-release state becomes lessened, is selected, thereby making it so as to change into the desired shift gear speed by way of the selected shift speed. In the case of an automatic transmission in illustration, when a jumping shift from the first gear speed to the fifth one is carried out, it is performed by way of the 2.5 and 3.5 speeds as in illustration. With this method, any rotating member remains unchanged in the case where the cumulative variation revolution is directly changed to the first gear speed to the fifth one, therefore the number of these friction engaging means selecting the engagement-release state simultaneously in substance becomes less than two.
