Title: Buffer managing system
Inventor: ETO KEIYA
IPC: G06F12/12
Filed: 1990-09-19
Abstract: PURPOSE:To execute the pool management of an unused buffer area in a state that a real memory is not allocated fixedly by rejecting the real memory as for an unnecessary buffer pool, that is, setting it to a state that it is taken away easily by invalidating a reference/updating bit. CONSTITUTION:The system is provided with a real memory allocating device 1, a real memory rejecting device 2, and a buffer pool managing device 3. In such a state, at the time of opening a buffer area of a fixed state of a real memory, the real memory is set to a state that the real memory allocating device 1 can take away easily the real memory, that is, a state that the correspondence of a logical address - a real address can be detached easily by invalidating only a reference/updating bit on a page table by the real memory rejecting device 2 without opening the real memory, that is, without erasing an entry from the page table. In such a way, an unused buffer area is managed in a state that the real memory is not allocated fixedly.

Title: Aligner
Inventor: TSUTSUI SHINJI
IPC: H01L21/30
Filed: 1987-10-01
Abstract: PURPOSE:To enable the masking effect to be brought about even in a reflection type projection exposure device wherein a masking mechanism can not be located in the conventional irradiating optical system by a method wherein the masking mechanism is displaced together with a mask and a substrate to be exposed. CONSTITUTION:A masking mechanism is fixed to a carriage F on the position below a mask 2. Four each of shielding films 10a-10d are independently driven by respective pulse motors 11a-11d so that the light transmitting the mask 2 may be shielded selectively by these films 10a-10d consequently to expose the oblique lined part 12 only. The pulse motors 11a-11d are drive-controlled by a control mechanism to form a specifically shielded region. Even if this masking mechanism is located on the position immediately above a substrate 3 to be exposed, entirely the same effect can be brought about. Through these procesures, even in an exposure device D wherein the mask 2 is not fixed to an optical system, the exposure range can be selectively limited.

Title: Member made of ti or ti-base alloy excellent in high temperature oxidation resistance
Inventor: SATO HIROSHI
IPC: C23C14/48
Filed: 1989-09-26
Abstract: PURPOSE:To improve oxidation resistance at high temp. without deteriorating the workability of Ti or Ti alloy by implanting the ions of specific metals in the surface of a member composed of Ti or Ti alloy and forming a layer in which the above metallic elements are concentrated. CONSTITUTION:The ions of at least one kind among metallic elements, such as Cr, V, Nb, Ta, Fe, Mn, and W, are implanted in the surface of a member composed of Ti or Ti alloy, by which a dense layer of an alloy with Ti can be formed. Since the diffusion of O2 in TiO2 forming a passivating film on the surface of the member made of Ti or Ti alloy into the inner part of the member made of Ti or Ti alloy can be prevented and, as a result, the growth of a brittle oxide film due to the diffusion of O2 can be prevented even in a high-temp. oxidizing atmosphere, deterioration in oxidation resistance can be prevented while maintaining superior workability inherent in the member made of Ti or Ti alloy.

Title: Method of predicting and controlling temperature of boiler steam
Inventor: NAKAMURA NAOTOMI
IPC: F22B35/00
Filed: 1987-10-05
Abstract: PURPOSE: To accurately perform the prediction control of a steam temperature by obtaining the deviation value between an actual steam temperature and a set temperature value, adding a signal based on the deviation value to a signal from a prediction preceding signal generator and a signal based on the deviation value and creating this signal before a fuel starts to change.

Then, when the fuel is to be changed, the change in the fuel is started by a time delay after a fuel change push button is operated.  However, a prediction preceding signal with the demand of each kind of fuel and a change target value as variables is created when a push button PB is operated in advance and is outputted as the command signal of an operation terminal at a point when at least a fuel change is started, thus accurately performing the prediction control of the steam temperature of a boiler corresponding to complex conditions without any time delay.

Filed: 1991-09-03
Abstract: PURPOSE:To prevent the deviation of an attracting position and failure in transfer and to obtain a high quality image by providing a stepping motor and adjusting the carrying speed of a carrying belt. CONSTITUTION:The stepping motor 70 rotates only by prescribed degrees when a pulse is inputted to the motor 70 from a control part 9 via a motor driver 10 (including a speed controller). Its speed can be varied and controlled easily and accurately by changing the frequency of the applied pulse train. A resist roller pair 12 is driven by the stepping motor 70 via gears 71a-71d. Driving shafts 12a and 12b are supported by bearings 81 and 82 attached to side plates 80. The bearing 82 is pressurized in the direction of the other bearing 81 by a spring 72. Even when a normal transfer material is used, the speed at which the material is carried by the resist roller pair 12 is delicately changed by the variations in the diameters of the resist roller pair 12 and variation in the pressurizing force of the spring 72; however, the carrying speed is finely adjusted by changing the frequency of the pulse train applied to the stepping motor 70 and it can be matched with the carrying speed of the carry belt.

Title: Logical verification result comparator
Inventor: NARUTOMI NOBUHIDE
IPC: G06F11/26
Filed: 1992-08-27
Abstract: PURPOSE:To perform confirming work of logical verification results easily in a short time by comparing the signal value of an expected value pattern with the signal value of logical verification result at every period of a comparison value parameter. CONSTITUTION:A logical verification unit 3 receives an input pattern l and circuit connection information 2 and verifies the logic. A comparison information reading section 8 in a logical verification result comparator 7 reads in period or strobe point from comparison parameters 5. A logical verification result reading section 9 then reads in comparison objects, i.e., a signal and an ivent, from logical verification results 4 and an expected value pattern reading section 10 reads in an expected value pattern 6. A signal value comparing section 11 compares a logical verification result 4 at a strobe point for every period read in from the comparison parameter with the signal value of expected value pattern 6. If the comparison result is 'mismatch', an over strobe point/over period detecting section 15 makes a decision of 'over strobe point' or 'over period'.
