Title: Light source block for semiconductor laser
Inventor: MIWA KATSUMI
IPC: G02B7/00
Filed: 1986-05-07
Abstract: PURPOSE:To decrease a variation amount due to temperature change of the interval between a collimating lens and a semiconductor laser, by specifying a thermal expansion coefficient of a fixing member to which the semiconductor laser and the collimating lens are fixed. CONSTITUTION:A laser fixing plate 3 is formed by an aluminum plate whose thermal expansion coefficient alphaL is 2.3X10<-5>deg<-1>, a laser supporting seat 4 is provided projectingly on its laser fitting surface, and its projection height (l) is set to 15mm. A semiconductor laser 1 is attached to the laser supporting seat 4. A lens supporting base 6 is formed by a steel material whose thermal expansion coefficient alphap is 1.2X10<-5>deg<-1>, a V-groove 7 is formed along a laser optical axis X on the upper face, and it is stuck to a collimating lens 2 on this V-groove 7, and fixed by a band member 8. A reference surface H for crossing the laser optical axis X vertically is assumed in a connecting surface of the laser fixing plate 3 and the lens supporting plate 6, and a distance (p) between this reference surface H and a laser fixing point P is set to 29mm. In this way, a variation amount against a temperature variation of an interval size of the collimating lens and the semiconductor laser can be decreased.

Title: Punching method for coated metallic plate
IPC: B21D28/02
Filed: 1992-03-31
Abstract: PURPOSE:To suppress wear of a die so that its service life is prolonged by applying a room temperature dry type resin lubricant to a punch, and executing punching. CONSTITUTION:Punching is executed by applying a room temperature dry type resin lubricant to a punch. In the case the lubricant becomes dry, it becomes a resin coated film, therefore, the lubricant does not adhere to a coated film part of a coated steel plate. Also, since the lubricant is a room temperature dry type and necessitates no heating, a thermal distortion is not given to the punch at the time of drying, and a shape and dimensions are not varied. At the time of applying the lubricant to the punch, it can be applied uniformly by such methods as soaking the punch into the lubricant, a lubricant spray to the punch, etc.

Title: Semiconductor device and its manufacture
Inventor: ARIMOTO MAMORU
IPC: H01L29/78
Filed: 1994-05-19
Abstract: PURPOSE:To provide a MOS transistor which can optimize the reliability and driving capacity. CONSTITUTION:The gate electrode 7a of a PMOS transistor 16 is of such structure that the a silicon nitride film 5 is made on a polysilicon film 4. So, the height of the gate electrode 7a is higher than that of the gate electrode 7b by the amount of the silicon nitride film 5, and the width of a sidewall spacer 11 a is larger than that of a sidewall spacer 11b. By the ion implantation using each sidewall 11a and 11b as masks, source and drain regions are made. Accordingly, as regards the PMOS transistor 16, since the width of the sidewall spacer 11a is large, offset becomes large, and reliability (control capacity of short channel effect) is raised. On the other hand, as regards an NMOS transistor 15, since the width of the sidewall spacer 1b is small, the width of an n-region 9 becomes small, too, so the driving capacity is raised.

After that, the carbonized coals are loaded into a dry cooling tower 5 and then are quenched to recover underwater a fine coke duct with a grain diameter of 200 μm and classified to set its impregnation moisture to 10-20% in a moisture impregnating tank 6. In addition, several different types of coal duct crushed to the grain diameter of 50 μm or less using the crusher 3 are mixed so that the fluidity is 2-3. Further, a coal heavy oil 2 with a viscosity of 50 cp or less at 80 deg.C is added to the coal dust at an addition rate of 10-30% for the weight of carbon, and this mixture is introduced into a kneader 7.  The fine coke dust and the coal dust are kneaded by a kneader 8 at a mixing ratio of (8:2)-(6:4) to obtain the molded mixed coal of a double structure with an average diameter of 0.5-2 mm which comprises a coal sticking to a coke surface layer. Further, this molding is formed into a column with a diameter of 10-20 mm under pressure using a molding machine 9 and is activated through carbonization at a high temperature at a heading furnace 10.

Title: Microprogram controller
Inventor: TOMONO HARUHIKO
IPC: G06F11/08
Filed: 1978-08-31
Abstract: PURPOSE: To confirm operations easily with high reliability, by intentionally causing a data error to occur to a random bit by hardware.  
     CONSTITUTION: Through CS address assignment line 102, CPU3 finds microaddress μ-A in CS1 to control a read from CS1. Data with a check bit read out from CS1 is latched to EDAC circuit 2 before being transmitted to CPU3. In EDAC circuit 2, the existence of data errors is decided on by using the check bit. With no errors detected, CPU3 performs a process basing upon input data then proceeds to a next operation step. If an one-bit error is detected, clock hold signal CL-H is sent to CPU3 via signal line 101 and data whose error has been corrected are transferred to CPU. Then, CPU3 performs processes basing upon data whose error has been corrected.

Title: Temperature control device
Inventor: ITOU TOSHIO
IPC: G05D23/19
Filed: 1980-08-04
Abstract: PURPOSE:To elevate a copying speed and to effectively utilize electric power, by applying full voltage to a heater immediately after the electric power supply is turned on, and applying to the heater a pulse of duty ratio which is varied depending on whether an exposure lamp is lighted or not in the course of copying. CONSTITUTION:Immediately after an electric power supply 8 is turned on, an output of a temperature detector 3 is lower than that of a reference temperature setting circuit 4, therefore, full voltage is applied to a heater 10 by operating a heater pulse controlling circuit 2 by an output of a comparing circuit 5. When a temperature of the heater 10 rises and an output of the detector 3 coincides with that of the circuit 4, the circuit 5 stops an output of full voltage of the circuit 2. In this case, since an output of an exposure lamp controlling circuit 1 is in a low level, a pulse controlling circuit 7 supplies a pulse, for instance, corresponding to duty ratio 4/5, to a circuit 11, therefore, voltage is applied to the heater only in the pulse period whose duty ratio is 4/5. Subsequently, when an exposure lamp 9 is turned on, an output of the circuit 1 becomes high, the circuit 7 supplies a pulse, for instance, corresponding to duty ratio 2/5, to the circuit 11, and in this period, voltage is applied.

Abstract: PURPOSE:To remarkably improve the non-defective rate of each manufacturing process by a method wherein a substrate of an arbitrary thickness is enabled to use by separating a semiconductor substrate individually before etching and isolating a P-N junction. CONSTITUTION:Electrodes 22 and 23 are provided on both surfaces of the semiconductor substrate 21 having a P-N junction, which is adhered on a quartz plate 24 with wax 25 with the junction outside. Separated individually by means of a diamond cutter, the substrate 21 is etched resulting in adjustment of the P-N junction to a required area and shape. Finally, the substrate is individualized by being removed from the quartz substrate 24. This constitution enables to arbitrarily select the thickness of the semiconductor substrate and reduce the rate of defectives generated at the time of handling; the scribing surface of the P-N junction is removed by later etching, and therefore crystal defects do not generate.
