Title: Solid phase joining method for different kinds of materials
Inventor: SASADA YASUHIRO
IPC: B23K20/12
Filed: 1987-01-30
Abstract: PURPOSE:To prevent a deterioration of the joining performance without using an intermediate material, etc., by heating, etc., one hand before joining the different kinds of materials and providing a temperature difference between both materials in advance to allow the joint surfaces to come into contact with each other and applying the pressure in the contact direction to join both the materials integrally. CONSTITUTION:In the case of joining Zr or Ti 1 to stainless steel 2, respective members 2 ans 1 to be joined are fixed by chucks 4 and 5. The chuck 5 is fitted to a motor 6 for rotating at a high speed which is fixed on a base 7 for sliding. Before joining, the stainless steel 2 having few degree of deformation at the time of joining is heated by using a high-frequency induction heating coil 3 and when the stainless steel 2 attains the set temperature, the base 7 for sliding is moved to the stainless steel 2 side while rotating the Ti1 by the motor 6. Both the materials 1 and 2 are joined integrally by the frictional heat and pressure generated on the joining interface at this time. Since the temperature difference is provided between both the materials 1 and 2 and the degrees of deformation of the joining parts of both the materials at the time of joining are brought close before joining, the joining performance can be prevented from deteriorating.

Title: Detecting apparatus for floating fine particle
Inventor: TANIGUCHI MAKOTO
IPC: G01N21/53
Filed: 1991-02-15
Abstract: PURPOSE:To positively and easily compensate for the temperature characteristic of an output signal due to the temperature characteristic of a light emitting element. CONSTITUTION:The scattering light from a light emitting diode LD because of the floating fine particles such as smoke or dust is received by a photodiode PD thereby to detect the floating particles. The light emitting diode LD intermittently emits light. In this detecting apparatus, there is provided a sample hold circuit 18 which integrates the outputs from a photodetecting part B detecting the waves synchronously with the emitting cycle of the light emitting diode LD. The sample hold circuit 18 has a gain with the temperature characteristic negating the temperature change of the optical output of the light emitting diode LD. Therefore, a large current does not flow in a thermistor R5. The resistance value or constant of the part B never becomes difficult to be selected as a result of tone self heating, and accordingly the temperature compensation can be easily and positively carried out.

Title: Disk device
Inventor: SHIYOUJI MAKOTO
IPC: G11B17/04
Filed: 1984-02-08
Abstract: PURPOSE:To enable the titled device to write (record) or read (reproduce) quickly by continuing on-control of a switch during the time necessary for inserting a driving pin into a driving pin insertion hole. CONSTITUTION:When power is supplied to a power source terminal 22 with a disk 2 inserted to a rotary body 11, a flip-flop 40 is set in response to a power source on-detection signal, a transistor 23 is turned on and a motor 16 is driven. Consequently, the rotary body 11 also rotates and the driving pin 13 is fitted to a hole 2d. When the rotational number of the disk 2 increases and a ready detection signal is generated, the flip-flop is reset. Accordingly, the transistor 23 is turned off, rotation of the motor 16 is stopped, and a current in the light emission element is cut off. Thus, power consumption is reduced. When the rotary body 11 is rotated until the ready detection signal is generated, perfect coupling of the disk 2 and rotary body 11 is obtained. Thus, previous coupling of the disk 2 and rotary body becomes possible, and recording and reproducing can be started quickly.

Abstract: PURPOSE:To supply stably an image of good quality by supplying toner from a toner separate supplying means by a quantity corresponding to consumption in each range detected by a toner consumption detecting means. CONSTITUTION:A toner amount detection sensor is constituted by arraying plural photosensors at right angles to a form conveyance direction, and a light beam from a light emitting element is reflected by an original and detected as reflected light by a photodetecting element, thereby detecting whether there is an image or not from whether the reflected light is detected or not.

Detection results of the image pattern are summed up in the form conveyance direction and the toner supply device 5 supplies toner by deficiency for a range of high image density, i.e. large toner consumption. At this time, a solenoid in the toner supply device 5 at the side of a toner supply shaft 18 is turned on and the driving force of a motor 10 is transmitted to a driving-side coupling joint to rotate the toner supply shaft 18.

Title: Wafer holder
Inventor: MAKIMOTO HIROYUKI
IPC: H01L21/677
Filed: 1998-02-03
Abstract: PROBLEM TO BE SOLVED: To ensure that wafers are held and taken out even if their positions where the wafers are held vary because of deformation of cassettes which have occurred in a wafer processing step and catching of the wafers. SOLUTION: The front end face of a movable pawl support 20 presses the peripheral edge of a wafer W and moves the wafer W to a position where the wafer W abuts on the innermost surface C1 of a cassette C as a hand 1 moves forward. In this state the movable pawl support 20 is moved backward to such a position where a front plate spring 19 does not block an optical path LF from a front light-emitting section 25F to a front light-receiving section 27F and a rear plate spring 19 blocks an optical path LR from a rear light- emitting section 25R to a rear light-receiving section 27R is judged to be a properpositoin at which each wafer W can be held.  Therefore, even if the position where the wafer is held varies because of derogation of the cassette having occurred in a step of processing the wafer and catching of wafer inside the cassette, the wafer can be held and taken out by holding means. This can improve the reliability of the carrying work of a robot.

Next, a gas sensitive body 4 is made by forming a semiconductor 4 made of a-Fe2O3 covering the electrode 5 and the resistor 6. velocity of a rise in temperature of this detector differs by a kind of combustible gas and the value of electric resistance differs by the concentration of gas. Thus, the kind and concentration of gas are measured at the same time and also, in good sensitivity by one detecting element.
