IPC: H01L21/302
Filed: 1986-01-22
Abstract: PURPOSE:To obviate the need of processes such as formation of masks or windows or removal of masks that would be conducted before or after selectively etching a semiconductor wafer, by providing a laser light scanning mechanism for applying laser light onto the surface of the semiconductor wafer. CONSTITUTION:A vapor etching apparatus is provided with a laser optical system 2 mounted such that it guides laser light 3 from a YAG laser generator 1 onto a semiconductor wafer 3 and with a laser scanning system 5 mounted such that it moves a reflection mirror 6 within the laser optical system 2 so as to apply the laser light 3 through a laser transmitting window 7 to any selected position on the semiconductor wafer 4. The laser scanning system 5 makes it possible to heat a very small portion at any desired position on the semiconductor wafer 4 by means of the laser light 3, and the portion heated by the laser can be etched much more quickly than the other portions by vapor- phase etching gas supplied through an air feeding tube 9.

Title: Freeze drying
Inventor: NAGASHIMA SHINYA
IPC: C07C27/00
Filed: 1981-01-30
Abstract: PURPOSE: An aqueous solution contaning mannitol is subjected to drying where the water evaporation is effected at temperature lower than specific one to evaporate a specific amount of water at the beginning, thus producing the objective freeze-dried product used for an injection solution or the like containing mannitol as a diluent.  
     CONSTITUTION: In freeze drying of an aqueous solution of mannitol, the evaporation conditions are adjusted not so as to exceed -22°C in vaporization and at least 1%, preferably at least 5% water is vaporized at the beginning step, thus producing the objective freeze-dried product. The concentration of mannitol in the aqueous solution is preferably 1W10% based on the total water.  
     EFFECT: The freeze (continuous line)-thawing (dotted line) curve in the mannitol aqueous solution has a peak of the amount of unfreezing water at -22°C, which is caused by precipitation of the solute, and so a part of water is removed at a temperature lower than -22°C to reduce the unfreezing water and lower the shock by refreezing.

Abstract: PURPOSE:To reduce the height of a whole device and to miniaturize the device by causing the weight of the moving means of an optical head and the placing table of an information recording medium to be equal and mutually executing a reciprocating motion in a reverse direction while balance in weight is held. CONSTITUTION:When an optical card C is loaded on a placing table 10, a start signal is sent from a card hold detecting means to a motor control circuit and a motor 22 is turned repeatedly and inversely with a prescribed period. According to this turn, a pinion 21 executes the same turn and a carriage 14, which loads the placing table 10 and an optical head 17, is displaced always only by a same distance in the reverse direction at a same speed. In such a case, by almost equalizing the total weight in the loading stand 10 side and the total weight in the carriage 14 side, the both mutually play the role of a balancing weight and a shock in an X-direction generated at the time of inverting operation is canceled. Then, normal record reproducing is maintained. Thus, the height of the whole device reduced and the device is constituted in compact.

Title: Rebound control method of work tool
Inventor: DENISU JIEI HAUSUMAN
IPC: E02F3/84
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To control the rebound of a work tool by detecting a working pressure of an actuator device in a machine having an electric hydraulic system and detecting the rebounding start of a construction member. SOLUTION: An electric signal, which depicts the pressure in the end of a head of an actuator is transmitted to a microprocessor 36 by means of pressure sensors 56, 57, 57 and 59, which are connected to the end of the head. The microprocessor 36 compares a pressure level between peaks with a specified threshold value. When the detected level exceeds the threshold value, a variable force control 66 is adjusted in automatic mode. When the variable force control 66 is turned on, the actuator moves in the vertical direction with a controlled means while the pressure level between peaks remains within the level of the threshold value. This construction makes it possible to exclude rebound as soon as the rebound is generated and keep the surface of work off from a undulated state.

Title: Oscillation circuit
Inventor: SAITOU SHIYOUICHI
IPC: H03K3/354
Filed: 1984-01-27
Abstract: PURPOSE:To prevent the brekage of a semiconductor junction/separation structure and to secure stable oscillation, by discharging a capacity element so that the junctures of said element is not set at a negative potential. CONSTITUTION:When the potentials 16 and 17 of a capacity 18 are less than the threshold levels of elements 31 and 33, switch elements 32 and 34 as well as 12 and 14 are turned off with elements 12 and 13 turned on respectively. Therefore, a point 16 is grounded and the electric charge is supplied to a point 17 from a current source 10 via the element 13. Thus the potential is increased at the point 17. When the potential of the point 17 reaches the threshold level of the element 33, the element 34 is turned on. Thus the reset control is given to an FF19 to invert the output. A delay time is produced in a period when the output of the FF19 is inverted after the element 34 is turned on. During this delay time the capacity 18 performs discharging from the point 17 with the point 16 kept grounded to reduce the potential down to a point near zero. In such a way, the voltage of the capacity 18 is set at zero immediately before the elements 12 and 13 are achned to ON from OFF to avoid a negative potential of the point 16. At the same time, a negative potential is avoided at the point 17 when elements 12 and 13 are changed to ON from OFF.

The medium is loaded after insertion in this way and ejected by the operation of an ejection button. Further, the medium is loaded vertically by the operation of the receiver 10 or the like moving upward and downward.

Filed: 1989-01-25
Abstract: PURPOSE:To make a product to which a tact switch is assembled thinner and improve space factor by performing orthogonal conversion of driving force by means of interaction between a projection and an engaging note. CONSTITUTION:A tact switch 11 is put on the edge of a print board 10, and then, surface mounting is performed by soldering each terminal 19, 20. When the pressure operational force as indicated by an arrow is given to a hooked edge 17a of an operational body 17 projected to the side of a housing 12, the operational body 17 is moved to the left hand side in the drawing for a hemisphere 16a to be pushed out of an engaging hole 17b. A stem 16 descends thereby, and when it descends to a certain point, an inversion spring 15 is inversed for both of fixed contacts 13, 14 to be conducted and turned to the state of switch 'on'. When the pressure operational force is removed in this condition, the stem 16 is lifted up by the elasticity of the inversion spring 15 itself to be separated from the fixed contact 14, it turns to the state of switch 'off', to be restored to an initial state.
