Title: Photoelectric converter
Inventor: SATO TAMOTSU
IPC: H04N5/335
Filed: 1984-12-26
Abstract: PURPOSE:To improve the controlability of a photoelectric conversion characteristic by providing a driving means which applies a control voltage on a capacitor and/or a transmission gate on a readout means, and performing application of the control voltage on the capacitor through this transmission gate and/or the readout of a stored voltage. CONSTITUTION:A control pulse phi1 is applied on the electrode 7 of the capacitor through a transmission gate 201. A substrate potential Vss of nMOS is set up to an earth potential and the substrate potential VDD of pMOS to a desired positive potential. Therefore, the gate 201 turned and turned OFF at the earth potential when a control signal A is at VDD. Furthermore, because a relationship between an input voltage V1 and an output voltage V2 is alway V1=V2 when the gate 201 is ON regardless of the control signal A or a threshold voltage V1 etc. shown in the figure, the most suitable photoelectric conversion character istic of a photo sensor cell 30 can be selected easily and precisely by setting properly a voltage V1.

Title: Draw forming of crystalline glass
Inventor: WADA MASANORI
IPC: C03B23/047
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To mass-produce at reduced processing cost by heating and then cooling under specified conditions a preform consisting of crystalline glass. SOLUTION: For example, SiO2 -Al2 O3 -Li2 O-based crystalline glass is crystallized by specified heat treatment to effect deposition of β-quartz solid solution or β-spodumene solid solution as the main crystal, thus obtaining crystalline glass having devitrified domains. The resultant crystalline glass is molded into a preform 1 which is, in turn, fed, through a feed mechanism section 3, into a molding oven 4 where the preform 1 is heated to such a temperature as to be softened and deformable and subjected to draw forming by a tensilizing mechanism section 5 into a preform 2.  In this case, the preform 1 is heated to such a temperature as to be short of developing devitrified domains in the crystalline glass followed by heating to such a temperature as to be softened and deformable within a time of virtually not devitrifying the crystalline glass and then cooling within a time of virtually not devitrifying the crystalline glass, thus affording a crystallized glass form having properties such as desired mechanical strength and thermal expansion coefficient.

Title: Transparent laminate
Inventor: MINEO MASATO
IPC: B32B27/30
Filed: 1996-10-16
Abstract: PROBLEM TO BE SOLVED: To prevent warpage of a laminate, to enhance adhesive strength and impact resistant strength and to prevent emulsification of a PC plate by laminating a polyvinyl butyral(PVB) film, a resin layer having higher viscosity than the PVB film, and an intermediate film at the ambient temperature. SOLUTION: The transparent laminate 10 is formed by laminating an intermediate film 51, hot-melt urethane adhesive layer 41 and a PC plate 2 via a resin layer having higher viscosity than that of a PVB film on the PVB film of one or two glass plates at the ambient temperature. The film 51 is constituted to sandwich a resin layer 53 having higher viscosity than that of the PVB film at the ambient temperature between PVB films 52 of both sides. The layer 53 has flexibility at the ambient temperature, and absorbs a difference of expansion coefficients generated at the laminate of the glass plate and PC plate having different linear expansion coefficients at the time of heating. And, the layer 41 shuts off migration of plasticizer and additive contained in the film 52 to the plate 2 to prevent emulsification of the PC plate.

Title: Lsi tester
Inventor: NAKAIZUMI KAZUO
IPC: G01R31/28
Filed: 1996-10-16
Abstract: PROBLEM TO BE SOLVED: To reduce the number of ICs and to miniaturize a test head by incorporating a drive and a comparator that are mounted on a test head in one package for each object to be measured. SOLUTION: A driver 12 and a comparator 13 that are mounted on a test head 2 of an LSI tester are not incorporated in one package for each pin of DUTM (memory to be measured) 9-1 to 9-n, but are incorporated in one package for each of DUTM 9-1 to 9-n, thus the number of Ics such as pin electronics LSI 3-1-3-n can be reduced, a test head 2 is minimized, and a floor area can be reduced. Simultaneously, the distance between the pin electronics LSIs 3-1 to 3-n and the objet to be measured can be shortened, the transmission efficiency of a signal can be improved, and at the same time the I/O switching time of a test for the object to be measured can be reduced, thus a high-frequency measurement is made possible.

Title: Information recording and reproducing device
Inventor: MOTOMIYA YOSHINORI
IPC: G11B11/10
Filed: 1986-11-19
Abstract: PURPOSE:To apparently perform an erasure-write procedure in an actual time without erasing existing information more than needed and preserving record effectively, by holding erasure until a prescribed quantity of information to be recorded is detected, and starting the erasure when holding is canceled. CONSTITUTION:A data 309 transferred from the outside is stored is a buffer 303 in a sequence of an address number via a control part 301. Meanwhile, the information from the control part 301 is sent to a processor 307 via a register 302. Also, the storage address of the information outputted from the buffer is sent to the processor 307 by a control part 305 via a register 306. When the access of an optical head 204 to a recording start position is recognized by the information from a control part 201, the processor 307 calculates an information quantity accumulated in the buffer 303 and compares it with a set value. The erasure is held until the information quantity arrives at the set value, and when it arrives at the set value, the erasure is started.

Title: Impact type dot printer
Inventor: SAKAIDA ATSUO
IPC: B41J2/295
Filed: 1988-10-28
Abstract: PURPOSE:To keep printing quality good by a method wherein predetermined magnitude dynamic voltage plus static voltage are impressed to a piezoelectric element according to a dot printing command, and a printing wire is pressured onto a printing medium. CONSTITUTION:While a transistor TR1 is on, electric charge of a second DC power source E2 is transferred to a piezoelectric element P via the transistor TR1 and a coil L. Voltage VP of the piezoelectric element P rises from magnitude equal to first power source voltage VE1, and reaches magnitude equal to second power source voltage VE2. A printing wire 12 is pressured onto printing paper M via a printing ribbon, and a dot is printed. Printing pressure to be generated between the printing wire 12 and the printing paper M corresponds to a distance of a strobe to be generated to the printing wire 12 by increase of the voltage VP of the piezoelectric element P from the magnitude equal to the first power source voltage VE1 to the magnitude equal to the second power source voltage VE2. Even though either thickness of the printing paper M varies at each printing start time or an initial gap varies by variation of temperature of the piezoelectric element P, a printing pressure dot suitable to the printing paper M is printed thereon, and excellent printing is always performed.

Title: Method for detecting filtering function of precoat type filter
Inventor: YOSHIOKA TAKESHI
IPC: B01D35/143
Filed: 1984-12-28
Abstract: PURPOSE:To prevent the damage of an apparatus by easily knowing that a precoat layer reached to a renewing period or by performing the estimation of the renewing period, by accurately displaying the filtering function of a filter on a meter even in a flow amount equal to or less than a reted flow amount. CONSTITUTION:The display scale on a meter of a flow amount and differential pressure is preset so that a reted flow amount value and the differential pressure limit value in said rated flow amount value are displayed on the same meter in th e same quantity in a superposed state. A time, when displayed flow amount display quantity coincides with differential pressure quantity, is detected as the limit of filtering function to know the renewing period of a precoat layer. For example, the rated flow amount value and the differential pressure limit vlue at that time are displayed on recording paper in the same quantity in a superposed state and, when the flow amount display quantity coincides with the differential pressure display quantity, the limit of filtering function is displayed to perform the renewal of the precoal layer. Therefore, the estimation of filtering function can be easily performed by the difference between display quantities of a flow amount and differential pressure even prior to the limit point thereof.

Filed: 1987-10-29
Abstract: PURPOSE: To interpret a writing utensil exchange status between a pen head and a pen stocker by determining the status of a sensor on the pen head side before and after a writing utensil exchange action. CONSTITUTION: A pen head 16 is equipped with a sensor 17 for detaching the presence of a writing utensil 20. A controller interprets that the pen head 16 has picked up the writing utensil 20 without an error, provided that the sensor 17 is set in the OFF position before a writing utensil exchange action and is set in the ON position after the writing utensil exchange action, when the pen head 16 fetches the writing utensil 20 held by a pen stocker 10. When the writing utensil 20 retained by the pen head 16 is returned to the writing utensil retaining part 14 of the pen stocker 10, the controller interprets that the pen head 16 has returned its writing utensil 20 to the writing utensil retaining part 14 of the pen stocker 10 without an error, provided that the sensor 17 is set in the ON position before the action and is set in the OFF position after the action.  In addition, when the pen head 16 returns the writing utensil 20 to the pen stocker 10, the controller interprets that because of the presence of the writing utensil 20 on both writing utensil retaining part 18 of the pen head 16 and writing utensil retaining part 14 of the pen stocker 10, returning the writing utensil 20 is impossible, provided that the sensor 17 is set in the ON position before and after the action.
