Title: Laser working device
Inventor: ISHIDA SHIYUUICHI
IPC: B23K26/00
Filed: 1984-02-21
Abstract: PURPOSE:To provide a titled device which improves the efficiency of a laser working operation and reduces the size and cost thereof by the constitution consisting in detecting the oscillation occurring in irradiation of a weak laser beam upon ending of penetration working of an object to be worked by the laser beam and detecting the working accuracy of the through-hole. CONSTITUTION:Electric power is supplied via a control part 6 for changeover of a power source from a main power source 7 to a laser oscillator 1 by the operation signal from a microcomputer 17 of a system control part 11 provided to a laser working device and a through-hole 9 is worked in an object 5 to be worked by a laser beam 2 outputted from said oscillator. The power source is changed over to an auxiliary power source 8 upon ending of such penetration working to output a laser beam 2 to the extent of not working the object 5 from the oscillator 1 and to irradiate the same on the hole 9. The oscillation occurring in such irradiation is detected by an oscillator detector 10 provided near the working region and is transmitted to the control part 11. The detection signal is compared with a set value in a relational decision part 15 via a voltage amplifier circuit 12, a full wave rectifier circuit 13 and an integrating circuit 14. Incomplete penetration is decided and the penetration working is resumed if the signal is larger than the set value. Completion of the penetration is decided and the working is stopped when the signal is smaller than the set value.

Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To make a device miniaturize and compact by reducing the moving widths of sliding bodies by engaging engaging parts provided in the respective sliding bodies with projecting parts provided in a disk reproducing part one by one and reducing the size of an up-and-down moving mechanism and its moving range. SOLUTION: An inclined groove necessary for moving a reproducing unit up and down within a specified height range is formed as inclined grooves 16 and 17 divided into first and second sliding bodies 14 and 15 and thus the lengths and the horizontal widths of the inclined grooves 16 and 17 are set short. In other words, the rising walls of the first and second sliding bodies 14 and 15 necessary for forming the grooves 16 and 17 are reduced in size and also the sliding width of each of the sliding bodies 14 and 15 is set narrow. Thus, a magazine 12 is attached/detached from the front side of a casing 11, and even when an area for installing the sliding body of the front side is largely regulated, because of the existence of such sliding bodies 14 and 15, these are easily assembled.

IPC: H03K5/02
Filed: 1993-02-22
Abstract: PURPOSE:To lower power consumption by reducing through current when output node potential changes between the potential which is higher than power source potential and the ground potential. CONSTITUTION:When the output signal phiout of an output node 111a rises from ground potential to boosted voltage Vpp, electric charge is supplied to a node 111a by a first (p) channel MOTr 111c and the fourth (n) channel MOSTr 113b of an electric charge supply circuit 113, the signal rises quickly and a second (p) channel MOSTr 111d becomes non-conductive immediately. Therefore, the time when through current flows in a ground node 20 from the boosting node 11 via a Tr 11d and a second (n) channel MOSTr 112b is short and power consumption is low. At the time of a fall, electric charge is supplied to an anti-output node 111b by Tr 111d and Tr 113a, the signal falls quickly and Tr 111c becomes non-conductive immediately. Therefore, the time when through current flows in the node 20 from the node 11 via Tr 111c and 112a is short and power consumption is low.

Title: Variable power lens system provided with auxiliary lens system
Inventor: FUJII KIYOSHI
IPC: G02B15/14
Filed: 1984-02-22
Abstract: PURPOSE:To convert a focal distance in a short time by a simple mechanism by providing an auxiliary lens system so as to be freely insertable and detachable between a front group and a rear group of a master lens system. CONSTITUTION:A master lens system consists of a front group having a positive refractive power and a rear group having a negative refractive power. An auxiliary lens system having a positive refractive power is provided so as to be freely insertable and detachable on an optical axis of the master lens system between said front group and rear group. The front group of the master lens system has a positive refractive power, therefore, a luminous flux parallel to the optical axis becomes a converged state, when it is emitted from the front group. When the auxiliary lens system is inserted between the front group and the rear group, since the auxiliary lens system has a positive refractive power, an image forming magnification of the auxiliary lens system becomes smaller than ''1'', and accordingly, it has a variable power action for shortening a focal distance of the whole system.

Abstract: PURPOSE:To ensure a sealing surface required by forming the inner diameter of a valve part smaller as a socket is proceeded to the rear side, and by forming the cross section of the valve part into rectangular shape protruded obliquely like a tongue to the center of a tube. CONSTITUTION:The inner diameter of a valve part 15 is made smaller as a socket 1 is proceeded to the rear side, and the cross section of the valve part is formed into almost rectangular shape protruded obliquely like a tongue to the center of a tube. When an inserting port 7 is inserted into the socket 1 for connection, at a time that a protrusion 8 on the front end outer periphery of the inserting port 7 passes the inner circumference of a rubber ring 3, the inner circumferential part of the valve part 15 is bent outside in the diametral direction as shown by a virtual line followed by a continuous line. The connection force can be smaller compared to in a case where the valve part of circular cross section is compressed. Connection can be facilitated while the sealing surface pressure required is ensured.

Title: New gene and new yeast containing the same
Inventor: TAKADA ISATO
IPC: C12N1/16
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To obtain a new gene consisting of a gene regulating the fermentative power of yeast at low temperatures, capable of making hosts sensitive at low temperatures through transferrin into yeast so as to make suitably usable in refrigerating bread dough, thus useful for breeding low-temperature-sensitive bread yeast. SOLUTION: This new gene regulates the fermentative power of yeast at low temperatures, is related to energy-acquiring system or saccharide's membrane permeation system, lies on the left arm of the 11th chromosome of the yeast, and consists of about 5.2kb EcoRI-EcoRI fragment having a restriction enzyme map shown by the formula. This gene is capable of making hosts sensitive at low temperatures through transferring into bread yeast, therefore being suitably usable in refrigerating bread dough and useful for breeding low- temperature-sensitive yeast.  This new gene is obtained, for example, by the following process: the parent strain of yeast is subjected to mutation treatment using e.g. ethyl methanesulfonate, a chromosome DNA is separated from the resultant variant followed by preparing a chromosome DNA library which, in turn, is put to screening with the reversion of low-temperature-sensitive hosts to wild type ones as indicator.

Title: Suction opening structure for water jet driving unit
Inventor: KOBAYASHI YOSHIAKI
IPC: B63H11/00
Filed: 1980-03-14
Abstract: PURPOSE: To prevent bigger floating matters from getting into a suction duct, by mounting to a suction opening grid rods at intervals.  
     CONSTITUTION: Water flow in the rear direction increases as it approaches a rear opening edge 32 of a suction opening 7. Therefore, floating matters got caught by the grid rods are gathered to the rear opening edge 32 of the suction opening 7. Because, however, a protruded part 30 is formed to each lower edge of the grid rods 28 which protrude lower than the rear opening edge 32, the floating matters caught by the grid rods 28 are pushed by the flow in the rear direction and come off from the rods 28. Therefore the floating matters do not accumulate around the grid rods 28, and the suction opening 7 is seldom covered with the floating matters, resulting in better suction performance and lesser resistance against driving. Furthermore, less labor is required to remove the bigger floating matters.
